|Note: By a large majority, F0 & F1 tornadoes occur more often than F2 to F5 tornadoes.
F0 Tornado Damage - Minor tornado damage; damage to chimneys, a few downed trees and power lines, large signs blown over, damaged porches and screen houses, and damaged lighter-weight outbuildings. Tornado wind speeds of 73 mph or less.
F1 Tornado Damage - Moderate tornado damage; mobile homes moved off foundations or overturned, roof surfaces peeled off buildings, cars blown off roads, several large trees downed and some power outages. Tornado wind speeds of 74 mph to 112 mph.
F2 to F5 Tornado Damage - Major tornado damage (up to complete destruction); mobile homes completely demolished, numerous large trees snapped off or totally uprooted, small debris objects (lawn mowers, smaller sections of roofs) become airborne missiles. Increasingly larger areas of power outages. Structural damage to sturdy buildings becomes a concern, beginning with roof and wall failures. In the worst situations, well-constructed walls fail or are even removed. Large debris objects (cars, larger sections of roofs) become airborne missiles causing further structural failures. Trees debarked. Tornado wind speeds 113 mph or greater, but in worse case situations 260 mph or greater.
