The St. Clair Region Conservation Authority has issued a flood outlook, as 10 to 15 mm of rain is expected to tonight, through to tomorrow.
“High water levels on Lake Huron, St. Clair River and Lake St. Clair, in addition to a wet spring, has resulted in elevated water levels across the watershed,” SCRCA officials stated.
“A low pressure system is anticipated to bring 10 to 15 mm of rain starting tonight through tomorrow. With water levels high across the region, particularly in Wallaceburg, this amount of rain may exacerbate current conditions and result in minor flooding into natural floodplain areas, agricultural fields and parks.”
Officials say a strong Wind Warning was issued for southern Lake Huron due to high winds forecasted into Thursday, there are record high water levels reached on Lake St. Clair and sustained high water levels in Wallaceburg.
Soils already saturated from rain and prolonged high water levels could contribute to ponding, increased runoff into watercourses, and possible increased erosion and seepage issues, SCRCA officials say.
“High amounts of rainfall in a short period of time can lead to increased runoff and flash flooding, particularly in urban areas,” SCRCA officials stated.
“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.
This message will remain in effect until Friday, June 21, 2019 unless otherwise updated.
