A look at some of the roughly 11 tornadoes that touched down in central Iowa Saturday

Dark clouds that loomed over central Iowa Saturday ended up producing around 11 tornadoes, according to the National Weather Service.

These tornadoes were very weak, according to officials. They hit a few trees and old rural buildings, but caused no structural damage to buildings in active use. No injuries or deaths have been reported. The National Weather Service will not be conducting a survey or report on the storms.

Isolated non-severe thunderstorms are possible Sunday, mostly south of Interstate 80, according to a hazardous weather outlook.
