Up to 8 inches of rain fell overnight in parts of southeast Minnesota, leading flash flooding and power outages. 

According to the National Weather Service, Olmsted, Dodge  and Fillmorecounties were hit the hardest as thunderstorms repeatedly developed over the same areas. Rainfall totals of 4-7 inches are widespread, with up to 8 inches in and around the Rochester area. 


"At 637 AM CDT, local law enforcement reported flash flooding occurring across much of western Olmsted and northern Dodge Counties where 4 to locally 8 inches of rain fell overnight," the flash flood warning issued by the La Crosse office of the National Weather Service (NWS) said. 

Flooding was reported in Rochester, Dodge Center, Mnatorville, Kasson, Byron, Oronoco, West Concord, Wasioja, Douglas, Rock Dell, Concord, Eden, Rochester Airport, and Oxbow Park.

"If flooding is observed, be prepared to seek higher ground, and remember to NEVER drive through flood waters. You never know just how deep the water really is," the NWS added.

The flash flood warning expires at 9 a.m., but it's also left some residents without power. 

"Rochester is experiencing flooding and power outages," Rochester Police Department said in a Facebook post. 

Olmsted County Emergency Management reported numerous flooded roads, with Rochester police urging people to avoid Hwy. 63 southbound from Hwy. 52 south to the Rochester Airport because of water over the roads.
