The flooding issues continue across Metro Detroit with more coastal flooding possible from Wednesday - Thursday afternoon. Strong northeasterly winds will set up, pushing the "already high" water levels towards the shore. This will create a prolonged situation of coastal flooding from Luna Pier to Sanilac.
Additional Coastal Flooding
There's also some river flooding taking place along the St. Clair River. St. Clair County's Emergency Management reported numerous buildings & roads being flooded in Algonac and Harsens Island along the St. Clair River. The river levels are expected to remain high enough to cause significant flooding into Friday. The high river levels are the result of the high water levels in the Great Lakes due to recent heavy rainfall and persistent strong north and east winds. The waters should start to slowly recede on Friday with winds becoming northwest and the ending of the rain.
Heavy Rain Returns
Our problematic easterly winds will be the result of a strong area of low pressure forming and moving towards Michigan. This will bring another round of heavy rain from Wednesday night into Thursday and some of the storms could be heavy with gusty winds. Since the ground is already saturated - it won't take much rain to cause some urban flooding. The good news is that the rain is expected to fall over 36 hours as oppose to 3. This is the opposite scenario of what happened last week around Dearborn.
