UPDATE: Rainfall Warning Ended

Update: Environment Canada lifted the rainfall warning just before 10am Monday.


After freezing rain blanketed the region on Saturday, southwestern Ontario is in for heavy rainfall on Sunday.

Environment Canada has issued rainfall warnings for much of the area, including London-Middlesex, Elgin, Oxford, Chatham-Kent, Windsor-Essex, Sarnia-Lambton, Huron, and Perth.

Forecasters say another dose of freezing rain on Sunday morning will be followed by significant rainfall throughout the rest of the day and into Sunday night.

“The rain may fall heavily at times with amounts likely in the 20 to 30 mm range,” the warning says. “Some additional rainfall is likely overnight into Monday, albeit lighter. Total rainfall amounts for the weekend may be in the 30 to 40 mm range with localized amounts of 50 to 60 mm possible.”

The freezing rain warnings have ended in Windsor-Essex, Chatham-Kent, London-Middlesex, Elgin and Sarnia-Lambton.

Environment Canada has scaled back its initial predictions regarding accumulation.

“The ice buildup won’t likely be as severe as earlier expected – perhaps up to 10 mm. However, strong winds gusting to 70 km/h in combination with the ice accumulation will likely still result in many power outages due to fallen trees limbs and power lines,” Environment Canada says.

As of 10pm Sunday, the rainfall warning for Chatham-Kent and Windsor-Essex had expired.
