Heavy rain expected in Toronto Thursday

Environment Canada has issued a rainfall warning for Toronto, where between 25 and 50 millimetres of rain is expected to fall between Thursday and Friday.

Two weather systems, one from Alberta, the other up from Texas, are expected to meet over the Great Lakes region early Thursday, turning out heavy rain and strong winds.

Rain — possibly preceded by snow, freezing rain or ice pellets — will hit Toronto by midday as the storm moves east from the Windsor-Sarnia area towards Kingston.

The rain will continue until Friday, and there is also a chance of thunderstorms. Additionally, the warm, wet weather may lead to “significant snow melt”, according to the weather service.

A new layer of snow fell on Toronto earlier this week and, with temperatures expected to hit 3 C on Thursday, there is fresh concern the city could experience some flooding.
