EF5 drought
Since 2013, the United States has experienced a record lack of tornadoes that have been rated EF5 on the Enhanced Fujita Scale by the National Weather Service.[1] This period, dubbed the EF5 drought or EF5 gap by some media outlets,[2] is the longest drought of EF5 tornadoes in recorded history.[3] The drought began following the 2013 Moore EF5 tornado; no EF5 tornadoes have been recorded worldwide since then.[4] Several tornadoes since May 2013 have subsequently been rated as high-end EF4; many of these ratings have attracted significant controversy, notably following the 2014 Mayflower–Vilonia, Arkansas EF4 tornado.[5] The drought has led to questioning whether the Enhanced Fujita scale is an effective way to rate tornadoes,[6] and a 2025 study found that the drought has had a 0.3% chance of running for as long as it has.[6] As of February 2025, the drought of officially-rated EF5 tornadoes is ongoing, spanning over 4,000 days.[2]
