Highlights:
- 5-10 mm rain tonight, upwards of 25 mm tomorrow
- Rain expected later in the week
- Water levels elevated
- Fast flowing water and slippery stream banks
- Potential road closures
A wet spring, coupled with elevated water levels in the St. Clair River and Lake St. Clair, has resulted in the Sydenham River remaining high throughout the watershed, particularly in Wallaceburg. The current forecast is calling for approximately 5 to 10 mm of rain tonight with an additional 10 to 25 mm overnight into tomorrow morning.
This amount of rainfall has the potential to elevate water levels over banks and into natural floodplain areas, agricultural fields and parks. Meteorologists are forecasting an additional 20 to 25 mm later in the week, which may increase flooding in the area. High intensity rainfall is possible, especially during thunderstorms. High amounts of rainfall in a short period of time can lead to increased runoff and flash flooding, particularly in urban areas. Soils already saturated from previous rain events could contribute to ponding and increased runoff into watercourses.
River banks 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.
