Mackinac County Flood History

Lakeshore Flood — Oct 21, 2019

Strong northerly to easterly winds resulted in another round of substantial coastal flooding and beach erosion, this time on both Lake Michigan and Lake Huron, for the 21st into the 22nd.

Flash Flood — Sep 24, 2010

Two days of heavy rain produced localized flooding in Eastern Upper Michigan. Rainfall amounts of 2 to 5 inches were common, most of which fell on the night of the 23rd. Raber picked up 4.75 inches of rain, Cedarville 4.10 inches, and St Ignace 3.40 inches.

Flash Flood — Aug 2, 2004

Numerous thunderstorms developed in a warm, moist, and unstable atmosphere ahead of a cold front. A number of storms became severe, mainly in Northeast Lower Michigan. A cluster of storms that moved through Eastern Upper Michigan in the morning produced locally heavy rain and some flooding.

Flash Flood — Apr 12, 2001

A combination of runoff from snowmelt and rainfall resulted in minor flooding primarily along the Pine River in the Upper Peninsula. Heavy rainfall was responsible for high water on the Manistee, Au Sable, Boardman, and Thunder Bay Rivers. No damage was reported though flood waters did rise onto some private property. Primarily, the water rose into yards and did not damage any structures.

Flash Flood — Jul 31, 1999

Bow echo moved east across much of eastern upper and northern lower Michigan ahead of a cold front moving over the upper Midwest. Numerous reports of straight line wind damage were associated with the bow. Storms with heavy rain ahead of bow caused some flooding across Mackinac county.
