A low pressure system tracking towards Ontario is expected to bring a cold front with strong northwest winds and lake effect snow to the Lake Huron shoreline Sunday night.

The Maitland Valley, and Ausable Bayfield Conservation Authorities have issued a flood watch for coastal areas. Grey Sauble Conservation has issued a watershed conditions statement.

Winds of 35-50 km/hr will begin early Sunday morning and shift from the south to northwest into the afternoon. Peak gusts of 70-100 km/hr are forecasted for Sunday night into Monday morning. Gusts of 40-60 km/hr will likely continue until Tuesday morning.

These strong, sustained northwest winds will produce significant wave heights. Combined with seasonally near record-high water levels on Lake Huron, wave action will reach far up the shoreline and bluff areas. Continued widespread erosion of both beaches and the lakeshore bluff is expected and flooding is expected in low-lying coastal areas.

Residents and municipal officials are reminded to stay well back from breaking waves. In addition, people should stay away from top-of-bluff areas during and after the storm in case there has been any movement of the lake bank.
