Strong winds today will result in continued erosion along the Lake Huron shoreline.
A cold front continues to move across southern Ontario today (Friday, April 30, 2021) and will bring strong sustained winds and waves to the Lake Huron shoreline. As winds pick up this morning, waves will continue to build through the day. Wind speeds over water will be steady at close to 45km/hr from a northwesterly direction. Gusts approaching 70km/hr are expected through today and into this evening. Winds are forecast to diminish tonight.
Lake Huron is nearly 30 cm lower than during major storm events last fall, therefore flooding impacts are expected to be less significant than those experienced in 2020 wind events. Continued erosion of the lakeshore bluff and beach areas is possible. Residents and municipal officials 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.
Maitland Conservation will continue to monitor watershed conditions and will provide an update if required.
