Carver County has already been hammered and more rain is coming.

Heavy thunderstorms are dropping significant amounts of rain in parts of Minnesota on Saturday, with southeastern Carver County already receiving in excess of four inches. 

A flash flood warning has been issued for the southeast portion of Carver County, where the National Weather Service says an additional 2-3 inches of rain could still fall.

The NWS is forecasting slow-moving thunderstorms to develop throughout the day with 2-4 inches of rain per hour in the strongest storms.
