- Strong southwesterly wind gusts between 40-60 km/h
- Possible storm surge, minor flooding
- Risk of thunderstorms
Winds from a southerly or westerly direction have the ability to create a backwater effect, slowing the flow of water out of the Sydenham River and elevating water levels in the Wallaceburg area. Residents along the Lake St. Clair shoreline may experience increased wave action with a potential for erosion, and quickly rising and falling water levels due to the wind. Minor flooding is possible in natural floodplain areas.
This event is also forecasted to bring a risk of thunderstorms and with 5–15 mm of rain across the region between this evening and tomorrow night, however localized precipitation amounts may vary. High amounts of rainfall in a short period of time can lead to increased runoff and flash flooding, particularly in urban areas.
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 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.
