Event narrative

Large trees were reported down in Lexington.

Wider weather episode

An early fall deepening low pressure system tracking along a frontal boundary delivered strong winds and heavy rain to southeast Michigan. Most areas saw rainfall totals of 2 to 5 inches, with locally 6 inches. Fortunately, just minor river flooding and flooding in low lying areas was reported, with the exception of Wayne county where localized flooding in Hamtramck stranded cars. More impactful, was the high winds along the shorelines of southern Lake Huron and Saginaw Bay, as north-northeast winds gusting between 40-60 mph were noted across Bay, St. Clair, Sanilac, and Huron Counties. Although downed trees and power lines were reported in Bangor Township in Bay County, the saturated ground likely contributed to trees falling with wind speeds under 55 mph. The persistent northeast winds over Saginaw Bay also caused elevated water levels and high waves which lead to lakeshore flooding and erosion along the shoreline, but no major structural damage was reported.
