A low pressure system over Iowa will continue to track eastward. This will bring heavy rain at times overnight and tomorrow to Northeast Michigan. Additionally, strong winds out of the east are expected Monday. The heaviest rainfall will be overnight and Monday morning, steady rain is still expected in the afternoon, then lighter showers in the evening.
The National Weather Service has issued a Flood Watch for most of Northern Michigan. Heavy rainfall will cause river levels to rise, and flooding is a significant concern for the counties shaded in dark green. The Flood Watch remains in effect through Monday evening.
Additionally, strong winds out of the east on Monday have prompted Lakeshore Flood Warnings to be issued from Alpena to Saginaw Bay. Shoreline erosion is likely for the counties shaded in bright green due to high waves, heavy rainfall and blustery winds. These warnings are in effect through Monday evening.
A Lakeshore Flood Advisory is in effect for Presque Isle County, where impacts due to lakeshore flooding are expected to be less in these areas, shaded in pale green.
Rainfall amounts will generally range from 1.5-3 inches across Northeast Michigan with locally lower amounts north, and locally heavier amounts south.
- Areas south of M-72 are expected to get the heaviest rainfall amounts, totaling 2.5-3.5 inches, Sunday evening through Monday night.
- Alpena will likely get close to 2 inches of rainfall.
