Message:

There is a Strong Wind Warning in effect for Western Lake Erie. Currently, winds are gentle to moderate across the region and generally from the south. Forecasts are predicting that winds will rise through the afternoon but stay from a south or southwest direction. Sustained winds speeds could climb above 30 km/hr late this afternoon, and most forecasts are suggesting they will climb above 35 km/hr early this evening. Some forecasts suggest sustained wind speeds could climb above 40 km/hr. Winds are expected to drop off overnight. Wave forecasts are generally calling for waves around 1.5 m in height with the 2 m waves on the open lake. There is also rain and the risk of thunderstorms in the forecast for this evening and overnight.

Due to high lake levels, there is a 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.

There is also a risk of flooding along Erie Shore Drive in Chatham-Kent from early this evening into the overnight period. The lower end of the predicted wind speeds are in the range where flooding just begins along Erie Shore Drive. If winds stay down in this range, little flooding would be expected. However, the upper end of the predicted wind speeds are well into the range that have previously caused flooding along this road and should the strong winds last for any significant length of time there could be flooding in the area. Residents and workers in the area should be prepared for the possibility of flooding. There could also be impacts to other low-lying shoreline areas that have seen flooding over the last few years.

Currently, winds are not predicted be from a direction to cause issues for the Lake St. Clair shoreline in the LTVCA jurisdiction.

People should take extra caution and avoid the shoreline should conditions get rough. The waves can be strong and the shoreline 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.

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

This message will be in effect until September 9, 2021.
