The 2012 Atlantic hurricane season has been a very active Atlantic hurricane season in the annual cycle of tropical cyclone formation that has so far seen 19 tropical storms, 10 hurricanes, and 1 major hurricane, exceeding the predicted maximum number of tropical storms and hurricanes, but so far has not exceeded the predicted number of major hurricanes. The season officially began on Friday, June 1, 2012 (2012-06-01), and ends on Friday, November 30, 2012 (2012-11-30). These dates conventionally delimit the period of each year when most tropical cyclones develop in the Atlantic basin.[1]

The season experienced an early burst of activity when Tropical Storm Alberto and Tropical Storm Beryl both developed several days before the official start of the season, an occurrence not seen since the 1908 Atlantic hurricane season.[2] When Tropical Storm Debby formed on June 23, it was the first time that four storms formed before July since record keeping began in 1851. The record pace stopped in July, with no tropical cyclones forming in July. This quiet streak quickly ended with Ernesto on August 1.[3] Eight named storms then formed in August, tying the record of most named storms for the month set in 2004. Several storms have affected land, including destructive hurricanes Isaac, which caused extensive damage along the Gulf Coast and especially in the state of Louisiana; and Sandy, which is currently active and the strongest storm of the season. Tropical Storms Beryl and Joyce, Hurricane Kirk, Hurricane Leslie, Hurricane Michael, and Tropical Storm Tony became the second earliest second, tenth, eleventh, twelfth, thirteenth, and nineteenth named storms, respectively. Hurricane Nadine became the 5th longest-lasting tropical cyclone on record. With the formation of Tropical Storm Tony, this season marked the first known occurrence of three hurricane seasons in a row with nineteen storms. Despite the presence of above-average sea surface temperature anomalies in the equatorial Pacific, the season is currently tied with 1887, 1995, 2010, and 2011 for the third most active Atlantic hurricane season in recorded history.

Forecasts of hurricane activity are issued before each hurricane season by noted hurricane experts Philip J. Klotzbach, William M. Gray, and their associates at Colorado State University; and separately by NOAA forecasters. CSU's December 2011 discussion was notable in that the forecasting team announced it would no longer attempt quantitative forecasting nearly six months out, noting "...forecasts of the last 20 years have not shown real-time forecast skill." They will, however, release a quantitative forecast for 2012 in April.[17]

Klotzbach's team (formerly led by Gray) defined the average number of storms per season (1981 to 2010) as 12.1 tropical storms, 6.4 hurricanes, 2.7 major hurricanes (storms reaching at least Category 3 strength in the Saffir-Simpson Hurricane Scale) and ACE Index 96.1.[4] NOAA defines a season as above-normal, near-normal or below-normal by a combination of the number of named storms, the number reaching hurricane strength, the number reaching major hurricane strength and ACE Index.[18]

Pre-season forecasts

On December 7, 2011, Tropical Storm Risk (TSR), a public consortium consisting of experts on insurance, risk management, and seasonal climate forecasting at University College London, issued an extended-range forecast predicting an above-average hurricane season. In its report, TSR noted that tropical cyclone activity could be about 49% above the 1950–2010 average, with 14.1 (±4.2) tropical storms, 6.7 (±3.0) hurricanes, and 3.3 (±1.6) major hurricanes anticipated, and a cumulative ACE index of 117 (±58).[5] Later that month on December 21, Weather Services International (WSI) issued an extended-range forecast predicting a near average hurricane season. In its forecast, WSI noted that a cooler North Atlantic Oscillation not seen in a decade, combined with weakening La Niña, would result in a near-average season with 12 named storms, 7 hurricanes, and 3 major hurricanes. They also predicted a near-average probability of a hurricane landfall on the United States coastline, with a slightly elevated chance on the Gulf Coast and a slightly reduced chance along the East Coast.[6] On April 4, 2012, Colorado State University (CSU) issued their updated forecast for the season, calling for a below-normal season due to an increased chance for the development of an El Niño during the season.[7] On April 12, 2012, Tropical Storm Risk (TSR) issued their update forecast for the season, slightly revising down their predictions as well.[8]

On May 24, 2012, NOAA released their forecast for the season, predicting a near-normal season (nine to 15 named storms, four to eight hurricanes, and one to three major hurricanes of Category 3 strength or higher on the Saffir-Simpson Hurricane Scale). NOAA based its forecast on higher wind shear, cooler temperatures in the Main Development Region of the Eastern Atlantic, and the continuance of the "high activity" era (i.e. Atlantic multidecadal oscillation warm phase) which began in 1995. Gerry Bell, lead seasonal forecaster at NOAA's Climate Prediction Center, added the main uncertainty in the outlook was how much below or above the 2012 season would be, and whether the high end of the predicted range is reached dependent on whether El Niño develops or stays in its current Neutral phase.[12] That same day, the United Kingdom Met Office (UKMO) issued a forecast of a below-average season. They predicted 10 named storms with a 70% chance that the number would be between 7 and 13. However, they do not issue forecasts on the number of hurricanes and major hurricanes. They also predicted an ACE index of 90 with a 70% chance that the index would be in the range 28 to 152.[11] On May 30, 2012, the Florida State University for Ocean-Atmospheric Prediction Studies (FSU COAPS) issued its annual Atlantic hurricane season forecast. The organization predicted 13 named storms, including 7 hurricanes, and an ACE index of 122.[13]

Mid-season outlooks

On June 1, 2012, Klotzbach's team issued their first updated forecast for the 2012 season, predicting 13 named storms, 5 hurricanes, and 2 major hurricanes. The university said there were large amounts of uncertainty concerning the phase of the ENSO as well as in Atlantic basin conditions. The organization also said the chance of a major hurricane hitting the U.S. coast was 48%, compared to an average of 52% over the past 100 years. The chance of a major hurricane hitting the Florida peninsula and the U.S. East Coast is 28%, compared to an average of 31% over the past 100 years.[14] On June 6, Tropical Storm Risk issued their June update for Atlantic hurricane activity for the 2012 season, predicting 14 named storms, 6 hurricanes, 3 major hurricanes, and an ACE index of 100. The agency noted that they anticipated the trade wind predictor to have a small suppressing effect on activity, and sea surface temperatures would provide a neutral effect. They continue with their forecast of a near-average chance of U.S. landfall activity using the 1950–2011 long term norm, but a slightly below-average chance of U.S. landfall activity using the recent 2002–2011 10-year norm.[15]

On August 9, 2012, NOAA revised its predictions saying more named storms are likely in this Atlantic hurricane season, as 3 tropical cyclones formed in the first week of August, even though a weak El Niño had formed. The agency now predicts between 12 and 17 named storms from the period that started on June 1 and will end on November 30. NOAA's original May prediction was between nine and 15 named storms.[16]

Tropical Storm Alberto

Tropical storm (SSHWS)
 
DurationMay 19 – May 22
Peak intensity60 mph (95 km/h) (1-min);
995 mbar (hPa)

During the early morning hours of May 19, a non-tropical area of low pressure became stationary just offshore of South Carolina while producing organized shower and thunderstorm activity.[19] It quickly gained tropical characteristics over the warm sea surface temperatures of the Gulf Stream, and by 2100 UTC that afternoon, the National Hurricane Center initiated advisories on Tropical Storm Alberto, the first named storm to form during May in the Atlantic basin since Arthur in 2008, and the earliest tropical storm since Ana in April 2003.[20] Combined with Aletta's preseason development in the Eastern Pacific, this became the first occurrence where tropical cyclones reached tropical storm status in both the Atlantic and Eastern Pacific basins (east of the 140°W) before the official start date of their respective hurricane seasons.[21]

At 2250 UTC on May 19, a ship near Alberto reported winds of 60 mph (95 km/h), indicating the storm was stronger than previously assessed.[22] Little strengthening occurred over the next few hours, and in fact, slight weakening occurred that night as southeasterly shear and dry air entrainment began to impact the system, leaving the center exposed to the east of the circulation.[23][24] After remaining a minimal tropical storm for about 24 hours, the storm weakened to a tropical depression early on May 22 as it moved northeastward out to sea.[25] Late on May 22, the NHC discontinued advisories on Alberto after the system failed to maintain convection and dissipated; at this time the cyclone was located roughly 170 miles (270 km) south-southeast of Cape Hatteras, North Carolina.[26] While the storm was active, Alberto produced 3 to 5 ft (0.91 to 1.52 m) waves, prompting several ocean rescues.[27]

Tropical Storm Beryl

Tropical storm (SSHWS)
 
DurationMay 26 – May 30
Peak intensity70 mph (110 km/h) (1-min);
992 mbar (hPa)
Main article: Tropical Storm Beryl (2012)

On May 23, an elongated low pressure area developed over the northwestern Caribbean Sea, with disorganized thunderstorms, and began moving northeastwards.[28] The low became better-defined over the Florida Keys,[29] and the cloud pattern organized.[30] After continuing to the northeast, the system developed a well-defined circulation with associated convection, located beneath an upper-level low. Based on the observations, the National Hurricane Center initiated advisories on Subtropical Storm Beryl at 0300 UTC on May 26 when the system was located about 305 mi (490 km) east of Charleston, South Carolina.[31]

Little change in strength occurred until May 27, when Beryl transitioned into a fully tropical storm and reached its peak intensity, with winds of 70 mph (110 km/h).[32] After making landfall in Jacksonville Beach, Florida, Beryl weakened to a tropical depression as it tracked over land.[33] The storm then slowly turned to the northeast,[34] tracking over Georgia and South Carolina before becoming post-tropical on May 30.[35] Beryl would soon become an extratropical cyclone, as it accelerated to the northeast.[35] Beryl's landfall in Jacksonville Beach, Florida, was the strongest landfall in the United States for any pre-season Atlantic tropical cyclone on record.[2]

Hurricane Chris

Category 1 hurricane (SSHWS)
 
DurationJune 19 – June 22
Peak intensity75 mph (120 km/h) (1-min);
987 mbar (hPa)

On June 17, a low pressure area developed from a stalled out frontal boundary near Bermuda.[36] Atop warm sea surface temperatures and light wind shear, the low pressure gradually acquired tropical characteristics the following day,[37] and during the afternoon hours of June 19, after sustaining deep thunderstorm activity for a sufficient amount of time, the National Hurricane Center began writing advisories on Tropical Storm Chris.[38] Despite being at a high latitude over cooler water (22°C / 71.6°F), it strengthened into the first hurricane of the season on June 21.[39] After encountering cooler waters, it weakened back to a tropical storm just six hours later.[40] Early on June 22 Chris began transitioning into a post-tropical cyclone as it interacted with a larger extratropical low to its south.[41] The final advisory on Chris was issued at on June 22 after completing its post-tropical transition, as it was absorbed by a larger non-tropical low.[42]

Tropical Storm Debby

Tropical storm (SSHWS)
 
DurationJune 23 – June 27
Peak intensity60 mph (95 km/h) (1-min);
990 mbar (hPa)
Main article: Tropical Storm Debby (2012)

A tropical disturbance developed into Tropical Storm Debby on the afternoon of June 23 in the Gulf of Mexico, becoming the earliest fourth storm on record in the Atlantic basin; this beat the previous record set by 2005's Hurricane Dennis, which formed on July 5.[43] Debby moved sluggishly throughout June 24 and into June 25, at times becoming stationary.[44] Debby did not intensify as much as originally anticipated due to high vertical wind shear caused by an upper-level low on its western side that limited convective activity atop the center of circulation.[45] At 2100 UTC June 26, Debby made landfall at Steinhatchee, Florida with winds of 40 mph (65 km/h). Shortly after landfall, Debby weakened to a tropical depression and lost most of its central convection.[46] Debby maintained tropical depression status while crossing Florida, while still being sheared from the southwest.[47] As it exited Florida during the afternoon hours of June 27, Debby was declared post-tropical due to lack of convection near its then elongated center, although it had regained tropical storm strength.[48] Over the next few days the remnants of Debby continued to move northeast until they dissipated on June 30.[49]

Hurricane Ernesto

Category 1 hurricane (SSHWS)
 
DurationAugust 1 – August 10
Peak intensity85 mph (140 km/h) (1-min);
980 mbar (hPa)
Main article: Hurricane Ernesto (2012)

A tropical wave exited the west coast of Africa on July 26 and developed into Tropical Depression Five late on August 1, while located about 810 mi (1305 km) east of the Lesser Antilles. Initially disorganized from wind shear,[50] the depression moved west-northwestward due to an anticyclone to its north.[51] Late on August 2, a Hurricane Hunters flight resulted in an upgrade to Tropical Storm Ernesto at 2100 UTC on August 2.[52] The next day, the storm moved over or very near Saint Lucia. By August 3, Ernesto entered the Caribbean Sea, with anticipation of further strengthening as a hurricane by the next several days.[53] As Ernesto approached the western Caribbean on August 5, wind shear and dry air briefly halted strengthening; deep convection diminished and the storm had an overall ragged appearance.[54] Nonetheless, Ernesto regained deep convection and became a hurricane on August 6.[55] Early on August 3, Ernesto made landfall in Costa Maya, Quintana Roo with winds of 85 mph (140 km/h).[56] After weakening to a tropical storm and moving into the Bay of Campeche, the storm struck Coatzacoalcos, Mexico on August 9.[57] The system weakened inland across Mexico and dissipated on August 10.[58] The remnants of Ernesto later contributed to the development of Tropical Storm Hector in the Eastern Pacific.[59]

In St. Lucia, a weather station on the island reported a wind gust of 63 mph (101 km/h).[60] In Mexico, the storm killed 2 people because of heavy rains.[61]

Tropical Storm Florence

Tropical storm (SSHWS)
 
DurationAugust 4 – August 6
Peak intensity60 mph (95 km/h) (1-min);
1000 mbar (hPa)

Late on August 1, a vigorous tropical wave emerged off the coast of Africa. The wave developed a mid-level spin, and on August 3, the National Hurricane Center began to monitor the wave.[62] The wave slowly organized, and on August 4, the storm became Tropical Depression Six.[63] The next day it strengthened into Tropical Storm Florence.[64] Environmental conditions were favorable at first, which allowed Florence to strengthen into a moderate tropical storm.[65] As the system progressed west-northwest, it encountered drier and more stable air, which caused Florence to weaken.[66] These unfavorable conditions finally took its toll on Florence when it weakened early on August 6 into a tropical depression, with the system almost void of thunderstorms and a vortex spinning in its center.[67] Later that day on August 6, Florence weakened into a post-tropical cyclone and the final advisory was issued by the National Hurricane Center.[68] After becoming post-tropical, the remains of Florence were still monitored by the National Hurricane Center as they continued to track west-northwestward while producing intermittent convection, although it never re-developed.[69]

Tropical Storm Helene

Main article: Tropical Storm Helene (2012)
Tropical storm (SSHWS)
 
DurationAugust 9 – August 19
Peak intensity45 mph (75 km/h) (1-min);
1004 mbar (hPa)

The National Hurricane Center began tracking a rapidly-moving tropical wave near Cape Verde on August 6.[70] The circulation began to organize on August 7, although thunderstorm activity was still disorganized.[71] Nonetheless, convection organized enough that Tropical Depression Seven formed on August 9.[72] However, minimal strengthening occurred and the depression instead degenerated into an open tropical wave on August 11.[73] The remnants were monitored for possible redevelopment, though on August 14, the system moved inland over Central America and was no longer expected to regenerate.[74]

After emerging into the Bay of Campeche, it redeveloped on August 17, though due to intensification, it was immediately re-classified as Tropical Storm Helene.[75] Helene moved northwest and made landfall near Tampico, Mexico on the following day.[76] Later that day, the storm was downgraded to a tropical depression, before dissipating early on August 19.[77] The remnant tropical wave produced heavy rainfall in Trinidad and Tobago, causing flooding and mudslides in Diego Martin on island of Trinidad. Two fatalities occurred and two other people were listed as missing.[78] Losses in Trinidad and Tobago reportedly exceeded 109 million TT$ ($17 million USD).[79]

Hurricane Gordon

Category 2 hurricane (SSHWS)
 
DurationAugust 15 – August 20
Peak intensity110 mph (175 km/h) (1-min);
965 mbar (hPa)

A tropical wave exited the coast of western Africa and entered the Atlantic Ocean on August 10.[80] After passing over Cape Verde, it traveled in a general west-northwest direction, over colder waters, during which its development had been impeded and its shower and thunderstorm activity remained minimal.[81] As the low pressure system turned to a more northerly direction, it reentered warmer waters. The environment was favorable for cyclone genesis, and the system attained a deeper convection and better defined circulation.[82] On August 15, Tropical Depression Eight formed about 630 miles (1,000 km) east-southeast of Bermuda,[83] and strengthened to Tropical Storm Gordon in about 12 hours.[84]

Gordon turned to the east and was expected to undergo extratropical transition upon passing over the Azores, where vertical shear was expected to increase.[85] Wind shear remained relatively absent, and after developing more convection around its center, Gordon was upgraded to a hurricane on August 18.[86] After peaking as a strong Category 2 hurricane, a weakening trend then occurred. On August 20, Gordon drifted over Santa Maria Island, hours before becoming extratropical.[87] Although Gordon passed directly over the easternmost islands in the Azores, little damage took place. Several homes had broken doors and windows and streets were covered with fallen trees. Some areas temporarily lost power when the storm moved over, though electricity was restored hours later.[88] Torrential rains also triggered localized flooding.[89]

Hurricane Isaac

Category 1 hurricane (SSHWS)
 
DurationAugust 21 – September 1
Peak intensity80 mph (130 km/h) (1-min);
968 mbar (hPa)
Main article: Hurricane Isaac (2012)

A tropical wave entered the Atlantic from the west coast of Africa by August 16 [90][91] and developed into Tropical Depression Nine on August 21. Located east of the Leeward Islands,[31] the depression intensified into Tropical Storm Isaac six hours later.[92] Further strengthening was slow however, due to dry air entering the northeast quadrant of the storm[93] as it was passing just south of Guadeloupe.[94] After an eye developed early on August 25,[95] shortly before Isaac made landfall near Jacmel, Haiti.[96] The storm disorganized over Haiti and emerged into the Windward Passage later that day,[97] soon followed by another landfall near the eastern tip of Cuba.[98] By early on August 26, Isaac entered the Straits of Florida,[99] though dry air prevented significant re-organization until Isaac reached the Gulf of Mexico.[100] At 1620 UTC on August 28, Isaac was upgraded to a Category 1 hurricane.[101] Later that day, Isaac made landfall near the mouth of the Mississippi River with winds of 80 mph (130 km/h).[102] The eye briefly moved offshore,[103] before another landfall in Louisiana near Port Fourchon on August 29.[104] Isaac weakened to a tropical storm later on August 29,[105] before being downgraded to a tropical depression late on the following day.[106] The depression continued in northerly direction, before transitioning into an extratropical cyclone over Missouri on September 1.[107]

Tropical Storm Joyce

Tropical storm (SSHWS)
 
DurationAugust 22 – August 24
Peak intensity40 mph (65 km/h) (1-min);
1006 mbar (hPa)

Early on August 20 the NHC reported that a Tropical Wave located between Africa and the Cape Verde islands was producing disorganized showers and thunderstorms.[108] Two days later it became sufficiently organized to be designated as Tropical Depression Ten, nearly 900 miles WSW of Cape Verde,[109] and on August 23 strengthened into Tropical Storm Joyce.[110] However, strong wind shear to the south of the storm's center of circulation inhibited further development; with most of the storm's convectional activity remaining displaced to the north, Joyce soon weakened to a tropical depression.[111] Joyce continued to weaken and the system fell below the threshold of a tropical depression, with its circulation no longer being closed. This prompted the NHC to issue the final advisory on Joyce at 11 am AST on August 24.[112]

Hurricane Kirk

Category 2 hurricane (SSHWS)
 
DurationAugust 28 – September 2
Peak intensity105 mph (165 km/h) (1-min);
970 mbar (hPa)

During the evening hours of August 22 the National Hurricane Center began monitoring a large tropical wave and associated, disorganized shower and thunderstorm activity.[113] Little change in organization occurred until late on August 25, when showers and thunderstorms associated with a newly-formed low pressure area increased. Wind shear increased atop the disturbance the following day however, and by 1200 UTC on August 27, the NHC had dropped the chances of tropical development down to 30%.[114] These unfavorable conditions were short-lived however, as deep convective activity once again increased over the low-level center. At 2100 UTC on August 28, the National Hurricane Center initiated advisories on newly-formed Tropical Depression Eleven.[115] At the subsequent advisory, the depression was upgraded to Tropical Storm Kirk, and the intensity forecast was increased significantly, as wind shear was not expected to be as much of an inhibitor as originally anticipated.[116] Slow intensification occurred over the following two days, and Kirk became the sixth hurricane of the 2012 Atlantic hurricane season at 1500 UTC on August 30,[117] before further intensifying into a Category 2 late that night.[118] After reaching its peak intensity with winds of 105 mph, the cyclone entered cooler waters and gradually weakened; the storm fell below hurricane status early on September 1, and became a post-tropical cyclone the next day while remaining far from land.[119]

Hurricane Leslie

Category 1 hurricane (SSHWS)
 
DurationAugust 30 – September 11
Peak intensity75 mph (120 km/h) (1-min);
968 mbar (hPa)
Main article: Hurricane Leslie (2012)

A tropical wave moved off the west coast of Africa on August 27 and entered the Atlantic Ocean.[120] Tracking generally westward and initially remained disorganized, though it began to develop deep convection around the center by early on August 30.[121] Later that day, the National Hurricane Center initiated advisories on Tropical Depression Twelve, which was located about 1,185 miles (1,905 km) east of the Windward Islands.[122] Due to warm sea surface temperatures,[123] the depression quickly intensified into Tropical Storm Leslie on August 30.[124] Although the storm significantly organized throughout August 30 and early on August 31,[125][126] wind shear began increasing thereafter, displacing convection from the center.[127] Despite disorganization, an eye-like feature appeared on satellite imagery early on September 1.[128] After re-organizing, Leslie was upgraded to a hurricane on September 5.[129] On September 11, Leslie made landfall over Marystown, Newfoundland and Labrador, Canada with winds of 70 mph (110 km/h) as it became extratropical.[130]

Hurricane Michael

Category 3 hurricane (SSHWS)
 
DurationSeptember 3 – September 11
Peak intensity115 mph (185 km/h) (1-min);
964 mbar (hPa)

On September 2, the National Hurricane Center noted a surface trough interacting with an upper level low northwest of the Cape Verde Islands, and began monitoring it for development.[131] It gradually became better organized and developed a surface circulation later that day.[132] On September 3, it finally developed enough organization to be declared a tropical depression,[133] strengthening to Tropical Storm Michael the next day.[134] Within its first 24 hours of tropical storm status, the system maintained little change in its strength.[135] However, the system became better organized, and strengthened enough to become classified as a hurricane on September 5.[136] Rapid intensification continued, and in two hours, Michael reached Category 2 intensity.[137] Four hours later, Michael became the first -- and so far the only -- major hurricane of 2012 in the Atlantic basin.[138]

Later that day, after holding Category 3 status for 12 hours, Michael dropped to a strong Category 2 and began to slowly weaken.[139] After− maintaining this intensity for over 48 hours, the system finally succumbed to high wind shear from nearby Tropical Storm Leslie and became a convectionless vortex by September 11, when it was declared a post-tropical cyclone by the National Hurricane Center.[140]

Hurricane Nadine

Category 1 hurricane (SSHWS)
 
DurationSeptember 11 – October 4
Peak intensity90 mph (150 km/h) (1-min);
978 mbar (hPa)
Main article: Hurricane Nadine (2012)

A large tropical wave moved off the west coast of Africa between September 7 and September 8.[141] Although dry air became a possible inhibitor for development,[142] Dvorak intensity estimates from the Satellite Analysis Branch (SAB) resulted in the National Hurricane Center initiating advisories on Tropical Depression Fourteen at 1500 UTC on September 11.[143] After an increase in deep convection, the depression was upgraded to Tropical Storm Nadine early on the following day.[144] Nadine continued to intensify while moving west-northwest and then northwest around the southwestern periphery of the subtropical ridge. However, late on September 13, moderate wind shear[145] displaced the low-level and mid-level center of the storm. However, the storm quickly re-organized and became a hurricane early on September 15.[146]

Nadine strengthened slightly further to 80 mph (130 km/h)[147] before weakening back to a tropical storm on September 17.[148] The storm continued to move eastward toward the Azores, but remained offshore. Nonetheless, Flores Island reported a wind gust of 46 mph (74 km/h).[149] After convection weakened, an upper-level low developed, and the wind field became larger than average, Nadine transitioned into a subtropical cyclone on September 21.[150] After no increase in convection, Nadine was declared to be a post-tropical cyclone early on the following day.[151] Later on September 22, thunderstorm activity blossomed near Nadine's center and persisted, leading to NHC redesignating the system a tropical storm on September 23. Nadine drifted westward thereafter, to the south of the Azores. On September 28, Nadine became a hurricane for the second time.[152] Due to wind shear the following day, Nadine weakened back into a tropical storm, but briefly restrengthened into a hurricane for the third time hours later. It reached its peak intensity of 90 mph on September 30,[153] holding on to its strength for 18 hours until it again started to weaken due to increasing wind shear and cooler waters. Nadine weakened to a minimal tropical storm on October 3, when it briefly reentered warm waters, thus dropping its pressure. On October 4, Nadine was picked up by the jet stream and eventually merged with a non-tropical system just before midday, prompting the NHC to discontinue advisories at that time.[154]

Tropical Storm Oscar

Tropical storm (SSHWS)
 
DurationOctober 3 – October 5
Peak intensity50 mph (85 km/h) (1-min);
997 mbar (hPa)

On September 30, a broad low pressure area formed a couple hundred miles west of the Cape Verde islands.[155] This low gradually became better organized as conditions were favorable for development,[156] and the NHC gave it a high chance of tropical cyclone formation (50% or more) on October 1.[157] The low developed into Tropical Depression Fifteen on October 3, with the NHC noting that the system had multiple swirls rotating around a common center. However, Fifteen was expected to strengthen only into a 45 mph tropical storm before being absorbed by a large extratropical low in 72 hours.[158]

On October 3, the cloud pattern of Fifteen morphed into a large cluster of cold-topped convection that had been steadily increasing in intensity and coverage.[159] An ASCAT scatterometer pass at 0030 UTC that day revealed several 40 mph wind barbs, and TAFB gave the system a Dvorak T-number of 2.5, equivalent to minimal tropical storm strength. On this basis, Fifteen was upgraded to Tropical Storm Oscar that day.[160] On October 4, the NHC reported that Oscar had strengthened despite hostile conditions, citing a 1300 UTC ASCAT pass that indicated that the strongest winds in Oscar had increased to 45 mph, but did not expect it to strengthen any further.[161] Late on the 4th, an ASCAT pass revealed that Oscar had strengthened a little more, to a 50 mph storm.[162] On October 5, visible satellite images and ASCAT data revealed that Oscar no longer had a closed circulation, and the convection that was left was confined to a small area and linear. On this basis, the NHC discontinued advisories on Oscar.[163]

Tropical Storm Patty

Tropical storm (SSHWS)
 
DurationOctober 11 – October 13
Peak intensity45 mph (75 km/h) (1-min);
1005 mbar (hPa)

A small area of low pressure formed northeast of The Bahamas in early October. Initially, the system slowly developed, but strong wind shear quickly prevented further intensification. After being situated in a hostile environment for about a day or so, the wind shear finally abated, allowing the system to deep convection and a well-defined circulation to develop. As a result, the National Hurricane Center initiated advisories on Tropical Depression Sixteen at 1500 UTC on October 11.[164] Later that day, Dvorak estimates from the TAFB and the SAB indicated winds of 50 mph (85 km/h), thus the National Hurricane Center upgraded the depression to Tropical Storm Patty.[165] Early on October 12, Patty strengthened to reach its maximum sustained wind speed of 45 mph (75 km/h).[166] However, strong wind shear soon weakened Patty, and by late on October 12, it was downgraded to a tropical depression.[167] Despite a burst in deep convection early on October 13,[168] Patty succumbed to wind shear as the circulation became elongated and appeared to no longer be closed. Thus, the National Hurricane Center discontinued advisories at 1500 UTC on October 13.[169]

Hurricane Rafael

Category 1 hurricane (SSHWS)
 
DurationOctober 12 – October 17
Peak intensity90 mph (150 km/h) (1-min);
969 mbar (hPa)
Main article: Hurricane Rafael

A tropical wave emerged into the Atlantic from the coast of Africa on October 5.[170] Convection slowly became more concentrated over the next four days as the system tracked westward.[171][172] After the system entered the Caribbean Sea, passing near Saint Lucia on October 12,[173] shortly before a Hurricane Hunters flight confirmed a closed circulation. Because tropical storm force winds were reported, the National Hurricane Center initiated advisories on Tropical Storm Rafael, while was located about 125 mi (200 km) west-southwest of Dominica. Initially, most of the deep convection was located to the east and southeast of the center, due to southwesterly wind shear from an upper-level low near Puerto Rico.[174] On the morning of October 13, Rafael was observed to be moving north-westward followed by a slight left turn caused by a rebuilding mid–level ridge. On October 15, Rafael strengthened into a Category 1 hurricane with winds of 85 mph (140 km/h) as it was moving northeast.[175] The storm continued to slowly intensify as it began to pass east of Bermuda, reaching its peak winds of 90 mph (150 km/h) early on October 16.[176] Soon after, it began to weaken very slowly as it entered an environment of very strong vertical wind shear and cooler sea surface temperatures. During the afternoon hours of October 17, Rafael transitioned into an extratropical cyclone, but remained powerful.[177]

A tropical wave was moving westward through the eastern Caribbean Sea on October 19.[178] It had an extended low pressure area, and conditions were expected to gradually become more favorable for development.[179] On October 20, the system became better organized, and the National Hurricane Center (NHC) assessed a high potential for it to become a tropical cyclone within 48 hours.[180] By the next day, the associated convection, or thunderstorms, had become minimal, although barometric pressure in the area remained low, which favored development.[181] The thunderstorms gradually increased, while the system slowed and became nearly stationary over the western Caribbean.[182][183] At 1500 UTC on October 22, the NHC initiated advisories on Tropical Depression Eighteen about 320 mi (515 km) south of Kingston, Jamaica. This was based on surface observations and satellite imagery, which indicated the system had developed enough organized convection to be classified.[31]

When the tropical depression formed, it was in an area of weak steering currents, located south of a ridge that extended eastward from the Gulf of Mexico. The system was in an area conducive for strengthening;[31] this included low wind shear and warm sea surface temperatures, and there was a possibility for rapid deepening. A Hurricane Hunters flight observed winds of 40 mph (64 km/h) in a rainband, which prompted the NHC to upgrade the depression to Tropical Storm Sandy.[184] Outflow increased, while the convection organized further due to a moist atmosphere. Due to the favorable conditions, the NHC noted: "remaining nearly stationary over the warm waters of southwestern Caribbean Sea is never a good sign for this time of year. These environmental parameters are generally conducive for rapid intensification to occur."[185]

Current storm information

As of 7 p.m. EDT (2300 UTC) October 29, Post-Tropical Cyclone Sandy is located within 20 nautical miles of 38°48′N 74°24′W / 38.8°N 74.4°W / 38.8; -74.4 (Sandy), about 30 mi (50 km) east-northeast of Cape May, New Jersey and about 20 mi (35 km) south of Atlantic City, New Jersey. Maximum sustained winds are 75 knots (85 mph, 140 km/h), with stronger gusts. Minimum central pressure is 946 mbar (hPa; 27.93 InHg), and the system is moving west-northwest at 24 kt (28 mph, 44 km/h).

Tropical Storm Tony

Tropical storm (SSHWS)
 
DurationOctober 22 – October 25
Peak intensity50 mph (85 km/h) (1-min);
1000 mbar (hPa)

During the evening hours of October 19, the National Hurricane Center began monitoring a tropical wave interacting with a cold-core upper-level low across the Central Atlantic.[186] Moving northwestward, the disturbance was initially embedded within an environment characterized by strong wind shear and abnormally dry air. However, a decrease in wind shear the following day led to a subsequent organization in the overall cloud pattern of the system. On October 20, the disturbance, now depicted with a well-defined area of low pressure and deep convection, the NHC noted that it now had a high chance of tropical cyclone formation within 48 hours.[187] Following satellite intensity estimates from SAB and TAFB that afternoon, the NHC deemed the low sufficiently well-organized to declare it as a tropical depression, but noted that dissipation was expected by Day 5.[188] Slow organized continued the following day as Tropical Depression Nineteen moved northward in the response of an upper-level low to its west, and a multitude of data led to the upgrade of the tropical depression to Tropical Storm Tony at 0300 UTC on October 24.[189] While slow organization occurred for the remainder of that day, a subsequent increase in wind shear during the pre-dawn hours of October 25 exposed the low-level center from the deepest convection. At 2100 UTC on October 25, the storm was designated post-tropical, at which time it was located southwest of the Azores Islands.[190]

The table on the right shows the ACE for each storm in the season. Broadly speaking, the ACE is a measure of the power of a hurricane multiplied by the length of time it existed, so storms that last a long time, (like Nadine) as well as particularly strong hurricanes (like Michael), have high ACEs. ACE is calculated for only full advisories on specifically tropical systems reaching or exceeding wind speeds of 34 knots (39 mph, 63 km/h), or tropical storm strength. Accordingly, tropical depressions are not included here. The ACE also does not include advisories where a storm is declared to be subtropical, so ACE is not shown when Tropical Storm Beryl or Hurricane Nadine were subtropical, for example. Later, the NHC reexamines the data, and produces a final report on each storm, which can lead to the ACE for a storm being revised either upward or downward. Until the final reports are issued, ACEs are, therefore, provisional.
