Night Time Tornado
Night Time TornadoesFrom 1950 to 2005, a mere 27.3% of tornadoes were nocturnal, yet 39.3% of tornado fatalities and 42.1% of killer tornado events occurred at night. Tornadoes during the overnight period (local midnight to sunrise) are 2.5 times as likely to kill as those occurring during the daytime hours. It is argued that a core reason why the national tornado fatality toll has not continued to decrease in the past few decades is due to the vulnerability to these nocturnal events. -

F5 Tornado
F5 TornadoPrior to 1950, assessments of F5 tornadoes are mostly based on the works of Thomas Grazulis. Between 1880 and 1950, the NCDC accepted 38 of his classifications as F5s. In addition to the accepted ones, he rated a further 25 during the same period.[8][9] From 1950–1970 tornadoes were assessed retrospectively, primarily using information recorded in government databases, and newspaper photographs and descriptions. Beginning in 1971, tornadoes were rated by the NWS using on-site damage surveys.[10]
