A severe storm system dumped four inches of rain on River Falls Wednesday afternoon, and more storms are coming through Wisconsin later in the day, with a chance of tornadoes and large hail added to the mix.
The National Weather Service updated its forecast for south-central Wisconsin at noon, but no severe weather watches or warnings had been issued as of 2 p.m.
Flash flood warnings are in effect in Pierce and St. Croix Counties, while Columbia County officials are looking at a rising Wisconsin River, expected to crest on Saturday at 18.5 feet, over 3 feet higher than the river currently is at.
"Because of the snow melt from the north and the predicted storms over the next couple of days, the Wisconsin River is expected to continue rising," said Kathy Johnson, emergency management coordinator for Columbia County.
Sandbags and sand is available at the highway department shop in Wyocena, and people living in low-lying areas near the river are asked to take appropriate actions if the river starts flooding.
In the Madison area, showers and thunderstorms are expected late Wednesday afternoon into Wednesday night, with the rain winding down on Thursday.
