Disaster declarations were declared for Macomb, Oakland and Wayne Counties because of severe flood damage, the governor said Wednesday.
"The flooding that continues to impact Southeastern Michigan is a disaster in every sense of the word," Gov. Rick Snyder said in a statement Wednesday.
At least two deaths were associated with heavy rains that pounded much of the lower peninsula this week. More than 4.5 inches of rain fell on parts of Detroit, flooding area homes and highways.
Snyder's office said authorities were working around the clock to deal with damage to personal property and infrastructure. The declaration means communities are eligible for state support to deal with the flooding.
"By taking this action, the state can fully coordinate and maximize efforts to support its local partners," the governor said.
The weather system responsible for Michigan flooding has moved east, dropping as much as 9 inches of rain on some areas.
