Environment Canada has issued a severe thunderstorm watch for much of southern Ontario, advising of the possibility of strong winds, large hail and heavy rain.

The watch covers areas as far south as Windsor and stretches up past the Algonquin Park area.

Some eastern portions of the province, including the City of Ottawa, are not covered by the advisory.

“Conditions are favourable for the development of severe thunderstorms this afternoon into this evening,” the weather agency said.

“Some of these thunderstorms may be capable of producing strong wind gusts up to 90 km/h, large hail up to 2 cm and heavy rain up to 50 mm within one hour.”

The watch comes after a strong storm system moved through parts of southern Ontario Saturday evening, bringing with it heavy rain, strong winds and lots of lightning. One person died on a golf course during the storm in Erin, Ont.

A heat warning is also in effect for a large portion of southern Ontario, stretching from the Windsor area up to Barrie and the northern York Region.

Hot and humid conditions are expected to continue for those areas possibly into Monday, with temperatures around 30 C and humidex values up to 42.

Bosacki said it’s expected to cool down Monday night.
