F1 Tornado

A Picture of an F1 Tornado Funnel

An F1 tornado is the second weakest tornado on the retired Fujita Scale. An F1 will have wind speeds between 73 and 112 mph (117 and 118 km/h). F1 tornadoes can cause moderate damage. On the Enhanced Fujita Scale, the tornado damage scale that replaced the Fujita Scale, an F1 tornado is now an EF1 tornado. An EF1 tornado has wind speeds between 86 and 110 mph (138 and 177 km/h).

A F1 tornado is weak, but has winds as strong as the weakest hurricane. It has wind speeds strong enough to tear off roofing surfaces. Mobile homes can be blown off their foundations and sometimes turned over. Motor vehicles in motion can be blown off the road. Small barns, detached garages and storage sheds could be destroyed.
