Flood watch issued

The St. Clair Region Conservation Authority (SCRCA)has issued a flood watch across the region, as 5-15mm of rain and a risk of thunderstorm is anticipated in the next 24 hours.

SCRCA officials upgraded a previous water safety bulletin issued on Friday.

“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,” SCRCA officials said in a media release issued just after 9:30 p.m. on Saturday, March 28, 2020.

“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.”

SCRCA officials say 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,” SCRCA officials stated.

“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, SCRCA officials say.

“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,” SCRCA officials stated.

“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, SCRCA officials added.

This flood watch will remain in effect until Tuesday, March 31, 2020 unless otherwise updated.
