Heavy Rain and Strong Winds beginning Friday Night

A system will move into Southern Ontario late Friday evening. The system will bring heavy rain to the province overnight into Saturday morning. As the system moves out of the area, wind speeds will increase before easing Sunday morning.

Rain will begin across the region Friday evening, becoming heavy at times, and continuing until Saturday afternoon when it will begin to taper off.

Across most of the region, 20 to 30 mm is expected for areas such as Windsor, Sarnia, Chatham, London, Hamilton, Niagara Falls, Kitchener, Orangeville, Toronto, Oshawa, Peterborough, Belleville and Kingston.

Other areas such as Goderich, Kincardine, Tobermory, Owen Sound, Barrie, Parry Sound, Bancroft, Cornwall and Ottawa can expect 10 to 20 mm.

Wind speeds will begin to increase Saturday afternoon and will peak late in the evening.

The strongest wind gusts are expected in areas such as Niagara Falls, Simcoe and St. Catharines. These areas can expect maximum wind gusts of 100 to 110 km/h, locally stronger.

All other areas can expect maximum wind gusts of 90 to 100 km/h, locally stronger.

Residents are encouraged to secure outdoor objects, and monitor for wind damage. Power outages are also possible.

Temperatures will be above seasonal with this system as well, with temperatures in the mid-teens expected across the region.
