Michigan
The derecho was not nearly as strong in Michigan as it was in Wisconsin. Many trees blew over and caused damage to homes and buildings as it moved into Manistee and Ludington. The storm spawned tornadoes as it moved into central Lower Michigan and two people were injured—one from an overturned mobile home and another from an overturned camper.
The derecho moved through Lower Michigan throughout the afternoon and evening before dissipating in northern Ohio around 1:30 a.m. EDT on July 5. A total of 1 million acres (4,000 km²) of forest were damaged or destroyed, and the storm caused a total of $30M damage (1977 dollars).
