A Lakeshore Flood Advisory is in effect today until 8 p.m. tonight, Thursday, for portions of Mason, Oceana, Muskegon, Allegan, Ottawa and Van Buren counties, according to an alert from the National Oceanic and Atmospheric Administration (NOAA).

The combination of high water levels, northwest winds gusting up to 40 mph and waves of 5 to 10 feet high could lead to flooding along the lakeshore and possible beach erosion. The highest waves are expected to be south of Grand Haven, states the NOAA website.

There are also hazardous swimming conditions for beaches from St. Joseph to Manistee, with “particularly dangerous conditions” at Stearns Park in Ludington, Mears State Park in Pentwater, Muskegon State Park, Holland State Park and North Beach in South Haven, NOAA states.

“Life threatening waves and currents are expected at the beaches. Swimming is not advised, especially since water temperatures are in the 50s. Avoid walking on piers as the high waves could sweep you off,” NOAA states.
