The rain in the region is part of a larger storm system that wreaked havoc yesterday in southern Ontario.

A tornado touched down in the community of Ayr, about 115 kilometres southwest of Toronto.

Western University’s Northern Tornadoes Project confirmed the twister touched down around 11 a.m. Saturday, bringing with it winds that reached 165 kilometres an hour.

The project’s executive director, David Sills, says his teams are still assessing how big the storm was.

“We’ve got trees down in every direction possible,” Sills added, but he admitted, “This one was on the weak side.”

Southern and southwestern Ontario are not the only parts of the province dealing with powerful winds and stormy weather.

Environment Canada has a heavy rainfall warning active in the North Bay area.

Up to 25 millimetres of rain is expected in the region throughout Sunday, with winds gusting up to 60 kilometres an hour throughout the day.
