The National Weather Service has issued a lakeshore flood advisory for Ottawa, Mason, Oceana and Muskegon counties from late Friday night to 7 p.m. Saturday.
Southwest winds and large waves will increase Friday night and Saturday. These will cause beach and dune erosion, and cause flooding along the Lake Michigan shoreline through Saturday. Areas north of Holland are most at risk.
— Winds out of the southwest at 25-35 mph.
— Waves of 6-9 feet.
— Beach and bluff erosion is expected, particularly between Port Sheldon and Stony Lake, including Grand Haven, Muskegon and Whitehall.
— Lakeshore flooding is also expected in low-lying areas and along river mouths.
— A lakeshore flood advisory indicates that onshore winds will generate flooding of low areas along the lakeshore.
