Update: Environment Canada has toned down a forecast that initially warned of an “incredible series of storms” hitting B.C.’s South Coast until Thursday.
The weather agency said a rainfall warning is still in effect for the northern sections of Metro Vancouver, mainly on the North Shore Mountains, which can expect up to 50 millimetres of rain.
The downpour is expected to ease off around midday Tuesday.
Heavy rain could still cause flash flooding and pooling water on roads, and residents are warned to watch for washouts near rivers, creeks and culverts.
Previous story: Environment Canada says B.C.’s South Coast is in for a soaking wet week that could lead to flash floods and washouts in some areas.
The weather agency issued rainfall warnings early Monday morning about an “incredible series of storms” set to hit Metro Vancouver, the Fraser Valley, Vancouver Island, and the Sunshine Coast.
“A subtropically-influenced airstream will bombard the mountains of Vancouver Island and the Lower Mainland from today through Thursday morning,” it said in a release.
“High rainfall rates and a prolonged period of rainy weather will create an extraordinary 3 to 4 day rain event.”
From 25 to 100 millimetres of rain are expected to hit by Tuesday morning alone, and drivers are warned to watch out for flash flooding and pooling water on roads.
The warm air is also expected to drive the freezing level up to 2,500 metres and potentially cause snow-melt that will send more water into drainage basins, creeks, and rivers.
Residents are urged to watch for potential washouts near rivers and culverts.
