Tornado watches and thunderstorm warnings were issued across Nebraska Saturday, but no tornadoes were reported. Heavy rain falling onto already saturated ground prompted flood warnings.

Most counties have received three to five inches of rain since storms first rolled through Thursday. Some communities in Dawson and Gosper counties reported receiving seven inches. Residents were filling sandbags to hold back rising floodwaters.

Flooding was also reported along Cottonwood Creek in Cheyenne County, where water was crossing U.S. Highway 30 east of Sidney.
