Leedey, Oklahoma 2017 fatalities
This tornado reportedly left more intense damage than the previous event did in Woodward. Many structures were swept away, leaving no debris or grass in some areas. Yards at some residences were stripped of their lawns and all vegetation, and several inches of topsoil were removed as well. The F5 rating is widely accepted, though the tornado was very slow-moving, which may have exacerbated the level of destruction to some extent.
Rated F5/EF5, or mentioned as a possible F5/EF5 by tornado expert Thomas P. Grazulis
1985 38 yrs ago
Niles, Ohio–Wheatland, Pennsylvania 2005 fatalities
1985 United States-Canadian tornado outbreak – This tornado caused F5 damage along much of its path through Niles and Wheatland. A shopping center in Niles was obliterated, sustaining F5 damage and several deaths. Metal girders at the center twisted and buckled.Well-built homes were swept away, and 75,000-pound (34,020 kg) petroleum storage tanks were ripped from their anchors and thrown hundreds of feet. Pavement was scoured from a parking lot, and a steel-frame trucking plant was obliterated and partially swept away with the beams severely mangled. Routing slips from the plant were found wedged into the remaining asphalt of parking lot. An airplane wing was carried 10 miles from where it originated.
Official F5/EF5; undisputed
2013 10 yrs ago
El Reno, Oklahoma 2015 fatalities
2013 El Reno tornado – Largest tornado on record at 2.6 miles (4.2 km) wide. Was initially rated EF5 based solely on mobile Doppler radar measurements, which recorded winds up to 295 mph (470 km/h). However, the most significant structural damage was rated EF3, as the tornado did not strike any buildings when the EF5 winds were recorded. Rating was eventually downgraded to EF3 because of this, though the practicality of the downgrade has been disputed by some meteorologists.
Officially ranked below F5/EF5, but rating is disputed; event may have been F5/EF5
