Flooding hits parts of Midwest, with evacuations in Michigan

People living along two mid-Michigan lakes and parts of a river were evacuated Tuesday following several days of heavy rain that produced flooding and put pressure on dams in the area.

Two Midland-area schools were opened for evacuees and more than 50 roads have been closed. The evacuations in Michigan followed days of heavy rains in parts of the Midwest that also brought flooding to Chicago and other parts of Illinois, as well as Ohio and other states.

“We were laying in bed when I heard sirens,” Jon St. Croix told the Midland Daily News. “A fire truck was driving around, broadcasting that (we needed) to evacuate. It’s a scary thing — you’re sleeping and awake to sirens.”

St. Croix, 62, his wife and a next-door neighbor were among more than a dozen people sheltering in one of the schools. Their home was not flooded, but St. Croix said he had seen flooding in the area.

Volunteers at the schools said about 120 vehicles were in the parking lots and about 30 people had been staying on cots inside, according to WNEM-TV.
