Hurricane Ida is a hurricane that has made landfall on Port Fourchon, Louisiana, and is the second most intense to strike the state on record, behind only Hurricane Katrina, and the joint strongest by maximum winds, along with the 1856 Last Island hurricane and Hurricane Laura. The ninth named storm, fourth hurricane and second major hurricane of the 2021 Atlantic hurricane season, Ida originated from a tropical wave first monitored by the National Hurricane Center (NHC) on August 23, moving into the Caribbean Sea and developing into a tropical storm on August 26, 2021. On August 27, 2021, Ida became a Category 1 hurricane and initiated rapid intensification on the next day, becoming a Category 2 hurricane at 18:00 UTC on August 28. Ida further intensified into a Category 3 hurricane by 06:00 UTC on August 29, and within an hour, became the first Category 4 hurricane of the season, after a period of explosive intensification in highly favorable conditions.

It made landfall on the exact anniversary that Hurricane Katrina did, in almost the same area. Katrina is the only hurricane to have made a Louisiana landfall with a lower central pressure. [1]

The state of Louisiana said this would be the biggest test on its levees since Katrina.

On August 23, the National Hurricane Center (NHC) first noted the potential for tropical cyclone development in the southwestern Caribbean Sea,[2] related to a tropical wave that entered the eastern Caribbean Sea on the same day.[3] By August 25, the NHC assessed a high likelihood of development as the wave moved westward through the Caribbean.[4] On the next day, the system's convection, or thunderstorms, became more organized to the south of Jamaica.[5] At 15:00 UTC on August 26, the NHC classified the system as Tropical Depression Nine, about 115 mi (180 km) south-southwest of Negril, Jamaica. The classification was due to the organization of the convection and the storm's circulation center. Upon its development, the depression was moving northwestward, steered by a ridge located over the western Atlantic Ocean. Favorable factors in the system's further development included warm waters of the northwestern Caribbean Sea, low wind shear, and a moist environment.[6] Late on August 26, a Hurricane Hunters flight indicated that the depression intensified into Tropical Storm Ida.[7] Initially, the storm had an asymmetric structure, with its strongest winds and deepest convection located east of the center. This was due to some southwesterly wind shear, which gradually lessened.[8] As Ida moved toward northwestern Cuba, its structure improved, with more outflow, increased rainbands, and the organization of the convection into a central dense overcast (CDO).[9] Ida then rapidly intensified, with its winds increasing by 35 mph (55 km/h) in just over 11 hours. Late on August 27, the NHC upgraded Ida to Category 1 hurricane status, based on observations made by the Hurricane Hunters.[10] Around the same time, the hurricane made landfall on Cuba's Isla de la Juventud.[11] Ida later made a second landfall in Pinar del Río, Cuba, at 23:20 UTC on the same day.[12]

With the cross-country Hurricane Nora in the East Pacific moving more northwesterly than previously predicted, environmental conditions became even more favorable for Ida, as it traversed north-westwards towards a warm-water eddy, caused by the Loop Current situated near the center of the Gulf of Mexico.[14] Ida subsequently underwent rapid intensification and strengthened into a Category 2 hurricane at 18:00 UTC on August 28,[15] and then into a Category 3 major hurricane by 06:00 UTC on August 29. Shortly after being upgraded to a major hurricane, the Hurricane Hunters recorded a rapid rate of deepening, with the system's minimum central pressure dropping from 955 mbar (28.20 inHg) to 948 mbar (27.99 inHg) in an hour.[16] By 07:00 UTC, Ida had further intensified into a Category 4 hurricane, with the storm's sustained winds reaching 130 mph (210 km/h).[17] As Ida neared the Louisiana coast, it further strengthened into a very powerful Category 4 hurricane, with 1-minute sustained wind speeds of 150 mph (240 km/h) and a minimum central barometric pressure of 933 mbar (27.55 inHg).[18] Satellite imagery showed Ida as a very well structured system, with slightly uneven cloud cover with more of the convection being in the southern quadrant as opposed to other quadrants. A clear, symmetrical eye was also apparent, with a robust center surrounding it. At 16:55 UTC, Ida made landfall near Port Fourchon, Louisiana, at wind speeds of 150 mph (240km/h) and pressure of 930 mbar (27.46 inHg) on August 29,[19] tying the 1856 Last Island hurricane and Hurricane Laura as the strongest on record in Louisiana, as measured by maximum sustained wind, and trailing only Hurricane Katrina, as measured by central pressure at landfall.[20][21]

Current storm information

As of 11:00 a.m. CDT (16:00 UTC) August 29, Hurricane Ida is located within 20 nautical miles of 28°54′N 90°06′W / 28.9°N 90.1°W / 28.9; -90.1 (Ida), about 60 mi (95 km) southeast of Houma and 70 mi (115 km) south of New Orleans. Maximum sustained winds are 130 knots (150 mph; 240 km/h), with gusts up to 150 knots (175 mph; 280 km/h). The minimum barometric pressure is 933 mbar (27.55 inHg), and the system is moving northwest at 11 knots (13 mph; 20 km/h). Hurricane-force winds extend outward up to 40 miles (65 km) from the center. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center of Ida.

Preparations

Caribbean

Hurricane Ida over western Cuba late on August 27

On August 28, 800 individuals, including teachers and students monitoring turtles on the Guanahacabibes Peninsula, were evacuated due to Ida, according to the head of civil defense in the area.[22] La Palma also sheltered 6,281 people from the storm.[23]

United States

Tornado watches and warnings were issued for parts of Louisiana, Alabama, and Mississippi on August 29. The SPC issued a 5% tornado risk the same day for the 3 states, which included an overall slight risk.[24][25] Over 16 feet of storm surge was anticipated for Louisiana, with an additional 6-9 feet for Mississippi, 3-5 feet for Alabama, and 1-3 feet for Florida.[26] A high risk for flash flooding was issued on August 29, encompassing much of New Orleans and surrounding areas.[27] A widespread area of 15-20 inches of rainfall was forecasted the day Ida made landfall.[28]

Louisiana

On August 27, the preseason game for the Arizona Cardinals and New Orleans Saints, originally supposed to be held the next day at Caesars Superdome, was cancelled due to the storm’s forecast of being a major hurricane at the time of its landfall. Before this, the game’s start was moved to Noon CDT from the originally scheduled 7 PM CDT.[29][30][31] Governor John Bel Edwards declared a state of emergency in response to the storm.[32] On August 28, 2021, New Orleans mayor LaToya Cantrell issued a mandatory evacuation for all parts of the city which are outside of its flood protections area.[33] Also on August 28, President Joe Biden signed an emergency declaration for Louisiana ahead of the storm.[34]

In a briefing that was held on August 28, one day prior to landfall, Edwards anticipated Ida to be one of the strongest hurricanes to affect the state since the 1850s.[35] The Governor also mentioned the Levee system in New Orleans, saying Ida "will be the most severe test of that system". This comes after the 2005 levee failures in Greater New Orleans due to Katrina.[36]

Mississippi

In Mississippi, at least 15 school districts and universities were ordered to close on Monday, August 30, 2021, along with a dozen casinos ahead of the impact of the storm.[37] Entergy Mississippi expected significant damage to the system in the Jackson metropolitan area.[38]

Impact

South America

The precursor to Ida triggered flooding in Western Venezuela on August 24, killing 20 people.[39]

Caribbean

In Cuba, numerous palm trees were downed on Isla de la Juventud due to hurricane-force winds that struck the island. La Fe alone recorded 43 knots (50 mph; 80km/h) winds and gusts up to 62 knots (71 mph; 114km/h) on August 27.[40][41] Many houses were also destroyed by strong winds and branches of trees were snapped in La Coloma, Pinar del Río.[42] Los Palacios and Consolación del Sur also lost electricity, according to a local newspaper in the province.[43] Despite the hurricane, many hospital workers continued to work under the rage of the storm.[44]
