The St. Clair Region Conservation Authority has issued an updated flood watch across the region.
SCRCA officials say upwards of 50 mm of rain has been received over the past 24 hours and an additional 15-20 mm of precipitation is anticipated through to Friday morning.
“High amounts of precipitation were received over the last 12 hours, ranging between 15-50 mm of rain, with an additional 15-20 mm anticipated over the next day,” SCRCA officials said in a media release.
“Water levels elevated from rainfall earlier in the week are expected to rise further, with the potential for localized flooding in floodplain areas, parks and farm fields.”
The Sydenham River in Wallaceburg is also being impacted, SCRCA officials say.
“Winds from a westerly direction are also anticipated to cause a backwater effect in the Wallaceburg area, slowing the flow of water out of the Sydenham River and contributing to elevated water levels,” SCRCA officials stated.
Soils are expected to be saturated from the rain and could contribute to ponding, increased runoff into watercourses, and possible increased erosion and seepage issues, SCRCA officials stated.
“High amounts of rainfall in a short period of time can lead to increased runoff and flash flooding, particularly in urban areas.”
Environment Canada has issued a Gale Warning for southern Lake Huron, as high winds of 65 km/h (35 knots) from a northwesterly direction are expected this evening, with waves building to 3 metres this afternoon, SCRCA officials say.
“The Lake Huron shoreline can anticipate sustained wind action and possible erosion, particularly the Old Lakeshore Road area of Brights Grove,” SCRCA officials stated.
“Strong winds of 55 km/h (30 knots) from a southwesterly becoming westerly direction may impact Lake St. Clair. Residents along this shoreline may experience wind-driven high water levels and wave action, with a potential for erosion.”
The following roads will be closed due to high water levels:
– Stanley Line east of Kimball Road.
– Pretty Road north of McCallum Line.
– Waterworks Road between Moore Line and Courtright Line.
River banks are expected to be slippery, with possible minor erosion, SCRCA officials stated.
“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 Saturday, November 2, 2019 unless otherwise updated.
