Part of the tornado outbreaks of 2020 |
A widespread and deadly tornado outbreak affected the Southeastern United States on Easter Sunday and Monday, April 12–13, 2020. Several tornadoes were responsible for prompting tornado emergencies, including the first one to be issued by the National Weather Service in Charleston, South Carolina.[7] A large squall line formed and tracked through the mid-Atlantic on April 13, prompting more tornado warnings and watches. A total of 15 watches were produced during the course of the event, two of which were designated Particularly Dangerous Situations.
Throughout the two-day outbreak, a total of 141 tornadoes touched down across 10 states, inflicting widespread and locally catastrophic damage. The outbreak ranks 4th for producing the most tornadoes in a 24-hour period, with 132 tornadoes occurring between 14:40 UTC April 12–13; that tally is surpassed only by the Tornado outbreak of March 31 – April 1, 2023 with 134, the 1974 Super Outbreak with 148 and the 2011 Super Outbreak with 219. The strongest tornado of the outbreak occurred in Southern Mississippi, and was given a high-end EF4 damage rating after producing estimated winds of 190 mph (310 km/h), reaching a width of 2.25 mi (3.62 km), and causing eight deaths. With a total of 32 tornado-related fatalities, the Easter outbreak was the deadliest tornado outbreak since April 27–30, 2014. To assist with recovery efforts, governors of five states declared a state of emergency. Relief efforts were complicated by social distancing requirements amid the COVID-19 pandemic.
