Toronto about to be hit with 'significant rainfall' as multi-day storm moves in

Environment Canada is warning that some parts of the city could see up to 75mm of rain and that thunderstorms and flooding are a possibility.

According to Environment Canada, some areas of the city could see up to 75mm of rain by early Thursday morning, with most of the city expecting 50 to 60 mm during this time.

Thunderstorms have also been forecasted, beginning on Tuesday evening and continuing until “at least” Wednesday night.

The heavy downpours could cause flash flooding and water pooling, says Environment Canada, adding that “localized flooding in low-lying areas is possible.”

According to Environment Canada, the rainfall will be brought on by a cold front and a moisture-laden low-pressure system coming from the American Mid-west. This front is seeing most of western Ontario under significant rainfall warnings. ​
