There were several reports of small hail. Up to 161,000 Consumers Energy customers lost power, including over 51,000 in Kent Co. According to PowerOutages.us there were over 1/4 million customers without power in the Great Lakes Region. We’re still at 140,000 without power at 9:09 pm Saturday.
This picture was taken by my daughter #2 Thurs. evening at Grand Haven. The high water level has moderate waves crashing over the breakwater. The windward side of the breakwaters can develop dangerous currents on breezy days. The wind pushes the water toward the pier (it’s actually a breakwater…piers allow water to go underneath them…breakwaters do not). With a south or southwest wind, like we have this PM, the south sides of the piers/breakwaters may have dangerous currents pushing you out toward the middle of the lake.
There was also an Air Quality Alert Saturday for Berrien, Cass, Van Buren, Allegan, Ottawa, Kent and Muskegon Counties. That has expired.
