Scattered showers have been moving through Northeast Michigan due to a low pressure system located near Detroit. Patchy showers will likely end by midday Tuesday.

Isaias has briefly restrengthened to a Category 1 Hurricane. After making landfall near Wilmington, N.C. it will likely become a tropical storm as winds drop below hurricane strength. This will bring flooding up the East Coast as Isaias continues to travel northward. Tropical Storm Warnings are in effect from coastal South Carolina to Maine.
