A violent tornado outbreak from April 25 – 28, 2011, affected the Southern and Eastern United States leaving catastrophic destruction in its wake, especially across the state of Alabama. The outbreak produced destructive tornadoes in Alabama, Arkansas, Georgia, Mississippi, North Carolina, Tennessee, and Virginia and affected several other areas throughout the Southern and Eastern United States. Widespread and destructive tornadoes occurred on each day of the outbreak so far.[3]

As of 8:05 a.m. EDT on April 29, 2011, over 300 people had been reported to have been killed as a result of the outbreak (the exact number is unknown, and various sources differ on the exact count); all except five of the deaths (it is not stated whether these are included in the total) occurred on April 27.[1][2] 210 of the deaths occurred in the state of Alabama alone.[1] April 27 was the deadliest tornado day in the United States since the Super Outbreak of April 3–4, 1974, and the second deadliest tornado day since modern tornado forecasting began in the 1950s.[4] More than 300 tornadoes have been reported over four days, including 211 in 16 states on April 27.[5]

Meteorological synopsis

This animation of satellite images from April 26 through the morning of April 28 shows the development of the weather system which spawned the tornadoes.

April 25

A large area of possible severe storms for April 25–27 was forecast as the NOAA-NWS-NCEP Storm Prediction Center (SPC) issued a moderate risk of severe weather for three consecutive days, centered over Arkansas through Tennessee. By the late-afternoon hours of April 25, several tornadoes had been reported across a few states, including two which caused significant damage in Oklahoma and Texas. At 3:25 pm CDT (2025 UTC), the SPC issued a Particularly dangerous situation (PDS) tornado watch for much of Arkansas and parts of Missouri, Oklahoma, Texas and Louisiana.[6] Tornadoes were scattered that day until early evening, when an intense tornadic cell tracked near the Little Rock metropolitan area and a tornado emergency was declared for Vilonia, Arkansas. Initial reports indicate that a tornado either 3 miles (4.8 km)[7] or 0.5 miles (0.80 km)[8] wide caused significant damage in the town.[7][9] Reports indicate four people were killed.[9]

In addition to the tornadoes, severe flooding is ongoing across a large area from the Red River valley to the Great Lakes.

April 26

A high risk of severe weather was issued for April 26 for portions of Louisiana, Arkansas, Oklahoma and Texas along and near the Interstate 30 corridor as conditions became even more favorable for extreme weather.[10] A large PDS tornado watch with very high tornado probabilities was issued that afternoon for that same area.[11] Widespread tornado warnings were issued in this area later that evening, and tornadoes caused damage.[12]

Tornado watches were also issued for the Lower Great Lakes in the afternoon hours, and supercells began to track across southern Michigan in the early evening.[12] Several counties in Michigan were placed under tornado warnings, including Kent, Montcalm, Ionia, Kalamazoo, Calhoun, Barry, Eaton, Midland, and Bay counties. A tornado was later confirmed in Allegan County. A possible funnel had been spotted in Kalamazoo County, and seven people were injured by a lightning strike in Kalamazoo.[13] Further east, severe thunderstorms caused scattered wind damage and large hail across Pennsylvania and New York.[14] 2 Inch diameter hail was reported in Lock Haven, Pennsylvania.[14] An isolated supercell moved across Central New York much of the afternoon, producing golf ball sized hail in Syracuse and spawned a very brief EF1 tornado in Verona Mills, causing primarily tree damage.

April 27

These houses in Ringgold, Georgia were completely destroyed by an EF4 tornado.

For the second day in a row, the SPC issued a high risk of severe weather for the Southern United States. Conditions for tornadoes became increasingly favorable for a major outbreak. During the afternoon, a tornado emergency was declared for Neshoba County, Mississippi as a large tornado was reported on the ground by storm spotters.

At around 5:10 p.m. CDT, a very large and exceptionally destructive tornado struck Tuscaloosa, Alabama.[15] About 40 minutes later, a tornado from the same parent supercell, possibly the same tornado, struck the northern suburbs of Birmingham, Alabama. A tornado emergency was issued for both cities. A debris ball was observed by the Birmingham NEXRAD[2], indicating that the tornado was causing extreme damage. Photos from the damage path showed total devastation. According to Tuscaloosa's emergency manager, interviewed on The Weather Channel at about 7:30 a.m. EDT on April 28, at least 32 people have been killed in Tuscaloosa. Search and rescue still continues in the city, so this death toll may rise further.[16]

A statewide review by emergency management officials has recorded 162 fatalities in Alabama.[16] Damage and power outages in the Huntsville area are so widespread that little information from the area has yet been reported. Severe tornado damage, including at least seven deaths, has also been reported in Ringgold, Georgia. A tornado alert was issued for Southern Ontario, and three tornadoes may have touched down.[17][18]

The Storm Prediction Center shows 180 tornadoes were reported in the preceding 24 hours.[19]

April 28

Tornado watches were issued for the Atlantic Seaboard from Pennsylvania to Florida, but tornadoes were predicted to weaken and become more isolated.[20] Even so, dozens of people were killed across the region and tornadoes were reported in Pennsylvania,[21] New York, Virginia,[22] North Carolina,[23] South Carolina,[24] and Georgia.[25] A tornado is suspected in Maryland.[26] Although tornado watches were issued, no tornadoes were spotted in New Jersey[27] or Washington, D.C.[22] In the wake of the tornadoes and severe thunderstorms, widespread flooding hit the Midwest, South, and Eastern Seaboard, with extensive flood and flash flood warnings issued.[28]

Southern Ontario did not see any additional tornadoes. However, heavy winds with gusts of over 80 mph in the aftermath of the storm caused one death and several injuries from falling trees and flying debris.[29] The storm surge along the Great Lakes was among the highest ever seen, causing severe damage to several boats.[29] Environment Canada issued wind warnings for most of Southwestern Ontario, with snow expected in the wake of the storm.[18] Possible unconfirmed tornadoes were reported southwest of Kitchener, Ontario.[30]

Most significant tornadoes

Vilonia tornado

The first killer tornado of the outbreak was a large EF2 that struck the small town of Vilonia, Arkansas (Faulkner County) around 7:30 pm CDT on April 25. A tornado warning was issued for the town roughly 30 minutes prior to the tornado's arrival and the relatively low loss of life is attributed to this lead time.[44] A tornado emergency was declared at 7:24 pm CDT for Vilonia shortly before the tornado struck.[45] Four people are known to have been killed in the town and many more injured. Numerous structures were also damaged or destroyed.[46] One mobile home was completely destroyed and debris from the home was scattered a significant distance from where it stood. Several other homes were reportedly leveled by the tornado. Within five minutes of the storm, local fire fighters arrived in the town and began search and rescue efforts.[44] Following the tornado, 85 members of the National Guard were deployed to assist in search and rescue, debris clearing, security and traffic control.[47]

Tuscaloosa/Birmingham tornado

A large wedge tornado tracked across Tuscaloosa County, Alabama, including the southern and eastern portions of Tuscaloosa around 5:10 p.m. CDT and continued northeast.[15] Debris from the tornado was reported to be falling from the sky across Birmingham over 20 miles away in Jefferson County. A skycam operated by local Fox affiliate WBRC (channel 6) captured video of the tornado as it struck Tuscaloosa.[48] Several stores and restaurants in a business district at the intersection of McFarland Boulevard and 15th Street, near the DCH Regional Medical Center, were destroyed by the tornado; buildings were also reported destroyed on 35th Street, between Interstate 359 and Martin Luther King Jr. Boulevard. As the tornado traveled east to 35th Street and Kauloosa Avenue, the Tuscaloosa Environmental Services and Cintas facilities suffered severe damage. Numerous homes in the Rosedale and Forest Lake neighborhoods, as well as a P&P Grocery store in Rosedale, were devastated.[49] The University of Alabama suspended its operations, cancelled its softball and rowing competitions, cancelled its final exams period, and postponed its commencement until August 6.[50]

Television cameras, including a skycam operated by ABC affiliate WBMA-LP/WCFT/WJSU (channels 58, 33 and 40; branded as "ABC 33/40"), captured the mile-wide tornado as it moved east-northeast across the western and northern suburbs of Birmingham around 6:00 p.m. CDT.[51] Initial reports indicate significant structural damage and a mile to 1½ mile wide damage path.

The supercell that produced the Tuscaloosa/Birmingham tornado may have had potentially record-breaking longevity as that particular storm traveled more than 280 miles across five states from Mississippi to North Carolina, with damage reported from multiple tornadoes spawned by the storm.[citation needed] Unofficial surveys have categorized the damage from the tornado that hit Tuscaloosa and the northwestern suburbs of Birmingham as EF4 and possibly EF5. The overall death toll is uncertain but initial reports from Tuscaloosa and Birmingham indicate at least 36 people were dead and over 600 injured in the Tuscaloosa area and at least 10 people confirmed dead from Concord and Pleasant Grove.[52] The number of fatalities is highly uncertain due to ongoing search and rescue efforts and is subject to revision following surveys on the track of the tornado from the National Weather Service.

Smithville tornado

A violent tornado struck Smithville, Mississippi, at 2:44 PM CDT on April 27. The damage path was less than three miles long, but was half a mile wide, and did extreme damage in Smithville. While initial reports indicated more widespread damage, the NWS damage survey reported EF5 damage, with 18 homes, a post office, a police station, and what was listed as the "water system" completely destroyed, with 52 homes and 7 businesses damaged to varying degrees. The homes were well-built, of recent construction, but the storm was violent enough that all appliances and plumbing fixtures in the damage path were "shredded or missing." 14 people were killed, and 40 injured. Information is still preliminary.[53]

This was the first confirmed EF5 tornado anywhere in the world since the Parkersburg, Iowa, tornado on May 25, 2008.

Non-tornadic events

Minor thunderstorms were reported as far north as Northern Ontario on the evening of April 26. Heavy rains and minor flooding were also reported in Northern Ontario from April 26-28. [54] [55] [56] [57] Windstorms were also reported in Southern Ontario which resulted in some injuries, including one death. [58] [59] [60]

Aftermath

Alabama Governor Robert J. Bentley declared a state of emergency in the state of Alabama, due to storm damage from severe thunderstorms earlier on April 27, as well as the forthcoming severe weather later that day.[61] In addition, state of emergency declarations were also placed in Arkansas, Kentucky, Mississippi, Missouri, Tennessee and Oklahoma, because of the flooding and tornadoes.[62] Following the tornado outbreak on the evening of April 27, President Barack Obama granted a federal emergency declaration for the state of Alabama, giving federal assistance, including search and rescue assets to the affected region.[63] More than 2,000 National Guard troops have been deployed to Alabama, assisting local and state first responders in search and rescue efforts.[64] It was announced on April 28, 2011 that Obama would be visiting the affected areas of Alabama on the 29th.[65]

Browns Ferry Nuclear Plant

Browns Ferry Nuclear Plant in Alabama was adversely affected by the outbreak forcing the plant to shut down[66]

The Chattanooga Times Free Press reported that the Tennessee Valley Authority had lost the ability to transmit power from its Browns Ferry Nuclear Plant. The loss of ability to transmit power from the plant had forced it to perform a cold shutdown while being run with diesel generators. Chief Operating Officer Bill McCollum of TVA stated that it could be weeks before the plant is up and running again.[66] The Nuclear Regulatory Commission stated at a press conference "The plants' conditions are stable and are being placed in a cooled-down condition."[67]
