Highlights:
- 5-15mm of rain, risk of thunderstorm anticipated in next 24hrs
- Strong winds, increased wave action and possible erosion
- Water levels rising
- Minor flooding possible
Variable amounts of rain have fallen across the region today, ranging between 10-40mm, with a risk of thunderstorm bringing an additional 5-15mm in the coming 24 hours. Water levels are rising and may elevate into natural floodplain areas, parks and farm fields. Soils may become saturated and could contribute to ponding, increased runoff into watercourses, and possible increased erosion and seepage issues. High amounts of rainfall in a short period of time can lead to increased runoff and flash flooding, particularly in urban areas.
Winds are anticipated to be from a southerly direction early Sunday morning, becoming southwesterly/westerly throughout the day and into the evening. Wind gusts are forecasted upwards of 65km/h, subsiding through Monday and switching to a northerly direction overnight into Tuesday. These winds are anticipated to cause backflow in Wallaceburg, resulting in elevated water levels and possible breaching of the bank. Residents along the Lake St. Clair shoreline may also experience wind-driven high water levels and wave action, with a potential for erosion.
River banks are expected to be slippery, with possible erosion. Residents are reminded to avoid watercourses and flooded areas due to slippery banks and cold, swift moving water, as well as shorelines during high-wind and wave action events. 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 Tuesday, March 31, 2020 unless otherwise updated.
