Conservation officials are warning of high water levels and possible flash flooding on roads due to torrential rainfall.
The Lower Thames Valley and St. Clair Region conservation authorities both issued watershed conditions statements on Tuesday ahead of significant rainfall overnight.
According to Environment Canada, 40-80mm of rain is expected from the remnants of Hurricane Beryl before tapering off on Thursday.
There is a potential for torrential downpours with rainfall rates of 20-40mm per hour. As a result, water levels are expected to rise rapidly and produce localized runoff. High amounts of rainfall in a short period of time could lead to pooling on roads and flash flooding.
Localized flooding could also be seen around the Lower Thames watershed.
Local residents are encouraged to avoid watercourses and flooded areas, as they can become dangerous due to slippery banks and cold, swift-moving water.
