- Risk of thunderstorm, upwards of 25 mm of rain
- Strong winds
- Possible storm surge and potential flooding
This system is anticipated to bring strong south/southwesterly winds over Lake St. Clair and Lake Huron starting early Wednesday morning before switching to westerly Thursday morning. Winds are anticipated to increase over the course of Wednesday, with gusts upwards of 55 km/h over Lakes St. Clair and Huron. Winds are anticipated to build overnight into early Thursday, gusting upwards of 65 km/h before subsiding Thursday evening.
Waves on Lake St. Clair are anticipated to build to one metre, with Lake Huron expecting up to one and one half metre by early Wednesday morning. Residents along these shorelines may experience wind-driven high water levels and wave action, with a potential for erosion. Winds from a southerly or westerly direction may cause a backwater effect in the Wallaceburg area, slowing the flow of water out of the Sydenham River and contributing to elevated water levels.
River banks and shorelines are expected to be slippery, with possible minor erosion. Residents are reminded to avoid watercourses and flooded areas due to slippery banks and cold, swift moving water. Children and pets should be kept away from the water.
The Conservation Authority continues to monitor watershed conditions and will issue advisories to municipalities and media should flood issues arise.
Municipal emergency response staff and road superintendents should monitor local conditions closely.
This message will remain in effect until Thursday, June 11, 2020, unless otherwise updated.
