Mississauga residents are being alerted to the possibility of localized flash flooding and other dangers near rivers and streams in the wake of severe thunderstorms that passed through the region last night (Aug. 21).

Credit Valley Conservation (CVC) officials issued a Flood Outlook Statement last night that remains in effect throughout today (Aug. 22).

Parts of Brampton were flooded last night after receiving more than 100 mm of rain.

CVC officials said Mississauga was looking at more than 50 mm of rain Sunday night and overnight into Monday.

“While no flooding is expected in the Credit River and its major tributaries, there is a possibility of localized flash floods and water pooling on roads and in flood-prone and low-lying urban areas,” the CVC said in its statement, noting that torrential rains last night could impact water levels and lead to other dangerous conditions around watercourses. “Streams and other waterways could become hazardous due to slippery and unstable banks, and from high water levels and fast-moving water.”

The CVC added that streams, rivers and shorelines could be hazardous, especially near culverts, bridges and dams.

“People are warned to stay away from all watercourses and to keep children and pets away.”

A Flood Outlook Statement is issued as an early notice of the potential for flooding based on weather forecasts of heavy rain, snow melt in the winter/spring, high winds and other conditions that could lead to high runoff, ice jams, shoreline flooding or erosion.

Environment Canada issued a severe thunderstorm warning last night (Aug. 21) for Mississauga, Brampton and Halton as a line of strong thunderstorms tracked across southern Ontario.

Based on the statement from CVC, City of Mississauga officials are also urging people to stay away from watercourses today.
