Strong Winds May Cause More Erosion Problems Along Lake Huron Shoreline
Northwest winds will strengthen across Lake Huron today (Friday May 8, 2020) and persist into this weekend. Maximum wind speeds of 35 km/hr, with gusts of up to 60 km/hr are in the forecast and are expected to peak Saturday afternoon.
The strong winds, combined with seasonally record-high water levels on Lake Huron, will result in waves reaching far up the shoreline and bluff areas. While waves are expected to be less severe than those experienced during recent wind events; current forecasts are for a longer duration event. Continued widespread erosion of both beaches and the lakeshore bluff is expected and there is a risk of flooding in some low-lying coastal areas. Significant erosion was observed after the April 20th event and an increased risk of bank failures can be expected with any subsequent high wave events.
Residents are reminded to stay well back from breaking waves, and to stay away from top-of-bluff areas during and after the storm, in case there has been any movement of the lake bank. It is important to remember that there may be a delay between erosion at the toe (bottom) of the bluff and subsequent bluff failure.
This message will remain in effect until 12:00 p.m. on Sunday May 10, 2020, unless local conditions warrant further updates. Maitland Conservation will continue to monitor conditions and will provide an update if required.
