Thanks - Looks like the I-94 cooridoor was hit from Detroit to Kalamazoo.
From West to East along I-94. Wayne County - Detroit
Washtenaw - Ann Arbor/Ypsilanti
Jackson seems unfazed.
Calhoun - Battle Creek/Albion/Marshall
Kalamazoo - Kalamazoo and Portage

The Rest: St Joseph is South of Kalamazoo in West MI.(Three Rivers)
Ingham is split on power. Okemos is fine, Lansing is hit bad.
Part of Lansing is also in Eaton County.
Ionia is between Lansing and Grand Rapids.
And Genesee County is centered by Flint(60 miles from Detroit, 40 miles from Lansing).

I should mention that Eaton borders Calhoun as well.
