Up to 75 mm planned for Greater Victoria; heaviest Sunday afternoon through early Monday
A weather system bringing “large amounts of rain” has hit southeastern Vancouver Island and the South Gulf Islands, and is expected to continue until Monday. Temperatures are forecast to be unusually warm on Sunday, with a maximum of 15 C.
A warning of rainfall, triggered by an “atmospheric river,” took effect late Saturday afternoon, predicting up to 75 mm of rain. Heavy rains could cause lightning floods and pooling of water on roads, Environment Canada said.
The rain warning includes Greater Victoria, Goldstream to Mill Bay, Duncan to Nanaimo, and Nanoose Bay to Fanny Bay.
Rainfall on the west coast is forecast to shed between 100 and 150 mm of rain by Monday morning. Port Renfrew can wait up to 150 mm while Tofino and Ucluelet could see up to 75 mm.
As the warm front approached Saturday, constant rain developed in the afternoon. The temperature is forecast to rise to 11 C on Sunday morning and hit 15 C by noon on Sunday.
Environment Canada has forecast that the rain will be strongest on Sunday afternoon until early Monday morning ahead of a cold front that is related to this system. Temperatures are expected to drop to 6 to 8 C by mid-week.
Alert is in place for the Malahat Highway from Goldstream to Mill Bay.
On the west coast, residents are warned river levels will rise and river flows will increase as a result of the heavy rainfall.
