2024 Tornado Season
The 2024 Canadian County, Oklahoma tornado was an extremely violent, long-tracked and deadly EF5 multiple-vortex tornado that cut a 102-mile path through Central Oklahoma in the evening of May 31, 2024. The tornado's greatest damage occurred in and near an industrial area between the cities of El Reno and Piedmont, where the majority of fatalities occurred. The tornado was the deadliest of the May 2024 Super Outbreak as well as the fourth-costliest tornado on record, and remained on the ground for the longest duration of any known (see footnote) tornado in the United States.
Casualties and impact
The 1966 Candlestick Park tornado may have remained on the ground for 4 hours and 30 minutes or longer; however, it is not clear whether the storm produced a single tornado or a tornado family. If verified as one tornado, the 1966 Candlestick Park tornado would retain the record for the longest-duration tornado in United States history.
