UPDATE:  All warnings have been cancelled for tornadoes and thunderstorms as of 2:30 p.m. Saturday, but the entire southeast Minnesota and northern Iowa region is under a Tornado Watch until 10 p.m. Saturday.

A Flash Flood Watch remains in effect until 1 a.m. Sunday because of thunderstorms over southern Minnesota and northern Iowa, which may intensify at times through the rest of Saturday. 

The National Weather Service advises that many of them will bring torrential rain. Combined with heavy rain that has already hit parts of the region, the risk for flash flooding and rapid rises on area creeks and rivers is higher than normal. Those with interest along rivers or near drainage systems should pay attention to rainfall rates this evening. If you encounter flooding, move to higher ground and NEVER drive through high water.

The Flash Flood Watch continues for the following counties: 

  • Iowa--Allamakee, Chickasaw, Clayton, Fayette, Floyd, Howard, Mitchell, and Winneshiek
  • Minnesota--Dodge, Fillmore, and Mower
  • Wisconsin--Crawford and Grant

Heavy rain expected Saturday evening combined with recent heavy rain could cause localized flash flooding.  Waterways could return to flood levels.

A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued. Flooding is harder to spot at night as well, so use extra caution if you have travel plans this Saturday night.
