A storm system that cut into the Upper Midwest on Thursday dumped torrential rainfall over parts of the region. The amount of rain that has fallen has not only set numerous records, but it has also resulted in serious flooding in Minnesota and Wisconsin.

The governors of Minnesota and Wisconsin declared emergencies for a large areas of their states on Thursday due to the severity of the flooding.

Southern Minnesota has been hit the hardest by the flooding. Upwards of 10 inches of rain has inundated parts of southwestern Minnesota over the past two days.

Minneapolis has received more than 3.0 inches of rain over the past two days, exceeding the normal monthly rainfall of 2.69 inches.

A record rainfall of 1.77 inches of rain was set at the Twin Cities International Airport on Thursday. The old daily rainfall record was 1.20 inches set in 1977.

Rochester, Minn., shattered the old daily record rainfall of 1.41 inches of rain set in 1985 when 4.10 inches fell on Thursday.

Small streams and rivers have been overflowing their banks onto surrounding land and roadways.

Rises along major rivers will occur over the next couple of weeks as flood waters trickle downstream.

Many roads and highways have been shut down, including a 7-mile stretch of U.S. 52 near Pine Island, Minn. The Minnesota Department of Transportation said that a culvert collapsed on the highway. This means that some lanes of the highway may be closed for a week.

Some large sink holes have developed along area roads, including Lemond Road in Owatonna, Minn.

Some communities have been deluged by so much rain that levees and dams are being stressed and tested.

Water was sloshing over a levee that was eroding with the excessive amount of floodwater pouring down on the Yellowstone Medicine River in Porter, Minn., on Thursday. The community was sandbagging as houses and some businesses were threatened by the water spilling over.

Sandbagging was occurring in Richland and Austin, Minn., as well.

Evacuations of homes and long-term care facilities have been necessitated in some areas of Minnesota and Wisconsin, where rising water was an imminent threat.

The flooding rainfall has come at the worst time for farmers as the fall harvest has barely begun.

Soybean crops in low-lying areas will not be able to withstand the standing water.

Fortunately, the weather will continue to dry out today.

Cool winds will whip in behind the storm, which will be moving into Canada. A few showers will be leftover around the Great Lakes region.

The next chance for rain will arrive with a fast-moving storm system dropping down from Canada on Saturday. Due to the anticipated quick movement of the storm, it should not contribute to more trouble for the region.
