DUNDEE, Mich. (AP) — Heavy rains earlier in the week and runoff from melting snow caused flooding in parts of southern Michigan including Monroe and Lenawee counties.

Water from the River Raisin in downtown Dundee, about 40 miles southwest of Detroit, left several buildings including the post office flooded.

The Monroe Evening News reports that a bridge there was closed to traffic because of flooding. Dundee village officials say they are making sandbags available to residents.

The National Weather Service has issued a flood warning for the River Raisin, which could crest Friday or Saturday.

Flooding also was reported in Blissfield, about 55 miles southwest of Detroit. The Daily Telegram of Adrian reports the Michigan Department of Transportation closed a bridge over the River Raisin in Blissfield. And downtown Adrian saw flooding-related road closings.
