Heavy rainfall expected in SE Minnesota; flash flood watch in effect


The threat of flash flooding remains even though the heavy rain forecast for southern Minnesota has shifted farther south, the National Weather Service notes.

Rainfall totals, which were forecast at several inches in southeastern Minnesota, have shifted downward to around 2 inches in the southeastern corner of the state and less than an inch in the metro area.

The heaviest of the rain is expected along and south of a line from Albert Lea, Minnesota, to south of Eau Claire, Wisconsin, where totals could be in excess of 2 inches, the National Weather Service says.

The northland is expected to remain dry Thursday, the weather service tweeted.

Flash flooding possible

Flooding could be seen in the southeastern part of the state, where the weather service has issued a flash flood watch until late Thursday.

The Minnesota Department of Transportation has also issued a travel advisory for Thursday ahead of the potential flooding in southern Minnesota, reminding motorists that roads may be closed or restricted without warning due to flash flooding.

Drivers are also reminded not to drive around barricades and if flash flooding occurs, abandon your vehicle and get to higher ground.

Check MnDOT's website for road conditions and updates.

The Centers for Disease Control and Prevention says half of all flood-related drownings occur when a vehicle is driven into hazardous flood waters, which has officials reminding people to "turn around, don't drown" if they come across a flooded roadway.

Six inches of water will reach the bottom of most passenger cars, which can cause the loss of control and possible stalling, MnDOT notes. A foot of water will float many vehicles, while 2 feet can carry most away – including SUVs and pick-up trucks.

The forecast is also prompting some outdoor events to reschedule, including Thursday's Songs on the Lawn concert in Mankato, the Mankato Free Press reports.

Rochester's Thursdays on First and Third is also canceled due to the weather, ABC 6 reports. The RedBall Project was supposed to be inflated at Thursday's event.
