Thunderstorms and strong winds possible in southern Ontario

Some active weather is possible in southern Ontario.

Environment Canada has issued a thunderstorm outlook for Tuesday which said that storms may occur.

The weather agency said all of southern Ontario and portions of northeastern Ontario could see isolated thunderstorms.

They may occur during the afternoon and evening.

Up to 20 mm of rain may fall locally, with a peak hourly amount of less than 15 mm.

Meanwhile, Environment Canada has also issued a significant weather outlook for Thursday for strong winds in part of the region.

That includes western portions of the Greater Toronto Area, Hamilton, Niagara Region, London, and Windsor.

“A low pressure system moving through southern Ontario is expected to bring strong wind gusts near 80 km/h Thursday afternoon,” forecasters said.

Loose objects could be tossed around.
