The forecast suggests sustained wind speeds from the southwest could exceed 40 km/h late Saturday with winds predicted to peak overnight reaching up to 50 km/h with gusts over 65 km/h. Winds are predicted to stay strong throughout Sunday before dropping off and switching more westerly late Sunday afternoon.
Wave forecasts predict wave heights of up to three meters on the open waters of Lake Erie and waves up to two meters could be seen in near-shore areas, the LTVCA said.
“In addition to concerns about waves overtopping shoreline protections and flooding from wave spray, there is a risk of freezing wave spray,” the LTVCA said. “Until temperatures rise back above freezing Sunday afternoon, any standing water or spray coming over the shoreline could freeze across the ground or onto structures.

“Any water making it to the roadway could lead to slippery conditions on the road, the LTVCA added. “Residents in the area should monitor local conditions and be prepared.
Due to high lake levels and wave conditions, there is some risk that wave action could damage shoreline protection works and cause erosion all along the Lake Erie shoreline in Chatham-Kent and Elgin County, including along the high bluff areas.
Winds are not predicted to cause issues along the Lake St. Clair shoreline in the LTVCA jurisdiction.
People should take extra deposit and avoid the shoreline should conditions get rough, the LTVCA said. The waves can be strong and the shoreline icy and slippery. There could also be hazardous debris within the waves and water which could be thrown onto the shore. Standing water can also present unseen hazards. Children and animals should be kept away from the water.
