There was a lot of straight-line wind action that did damage to homes, uprooted trees and downed power lines during the powerful storm that swept Michigan on Thursday night and Friday morning. But the National Weather Service says there were also several weak tornadoes spinning up along the storm’s leading edge.

The weather service additionally issued severe thunderstorm warnings for Benzie, Manistee, Van Buren, Allegan, Ottawa, Mason, Muskegon and Oceana counties. Gusts up to 70 mph and golf ball-size hail were expected in those areas.
