Message:

Environment Canada’s Marine Forecast has issued a Strong Wind Warning for Lake Erie due to predicted strong winds later today. Although the various forecasts differ slightly, they are generally calling for winds from the north or northwest approaching 30 km/hr with gusts exceeding 40 km/hr. Winds would be stronger over the open water. The most likely times for these wind peaks appear to be early this evening, but not all forecasts are in agreement. These winds could be expected to raise static water levels (i.e. before waves) in the area of Lighthouse Cove. Waves could reach 0.5 m on Lake St. Clair. Any waves will add on to the already record high water levels. In addition to the winds, Environment Canada has issued a Special Weather Statement due to the potential for 25 to 50 mm of rainfall today as a system with embedded thunderstorms passes through the region.

Due to the high lake levels on Lake St. Clair and predicted wind and wave action, there is a risk of additional flooding today in the community of Lighthouse Cove, most likely to occur in the early evening. There is also an increased risk of shoreline erosion and damage to shoreline protection works in the areas. On Lake Erie, the winds are forecasted to be offshore so there is less risk. The rainfall predicted for today would aggravate the flooding situation and could impact shoreline communities on both lakes. The groundwater table is high due to the lake levels and the ground can’t absorb any more water. Local watercourses in these areas are already full of lake water and can’t take any more. Any water from upstream making its way downstream into these areas could cause additional flooding. Residents in these areas should be prepared, pay attention to changing weather forecasts and local conditions.

People should take extra caution and avoid the shoreline and any waterways with elevated water levels. The waves on the lakes can be strong, and the shoreline and the banks of waterways can be slippery. There could also be hazardous debris within the waves and water which could be thrown onto the shoreline. Standing water can also present unseen hazards. Children and animals should be kept away from the water.

Officials will continue to monitor the situation and update this advisory if necessary.

This message will be in effect until June 21st, 2019.
