The tornado that swept through Lake City this week had peak wind speeds of up to 145 mph, according to the National Weather Service, which estimated the strength of the tornado after reviewing damage in the area.
It was the most powerful of more than two dozen suspected tornados that struck the state that day — the third-highest number of tornados in a single day since the weather service began tracking that information in 1980.
The Lake City tornado took shape about 2 1/2 miles west of town at about 3:54 p.m. on Wednesday and continued east for about 10 miles. It ended about 2 1/2 miles west of Lohrville.
No one was injured, but the tornado caused widespread damage to trees and tore part of the metal roof from a shed that holds school buses on the west side of town. Parts of it were flung nearly a quarter mile.
More significant damage happened east of town, where the tornado destroyed at least one house.
About 1,400 MidAmerican Energy customers were without electricity in the area after the tornado. Power was restored to almost all of them by the next morning.
