Environment and Climate Change Canada has issued a significant rainfall warning for parts of British Columbia's South Coast, with substantial precipitation expected to drench the region throughout the weekend.
Affected Areas and Rainfall Projections
The weather alert covers multiple regions across Metro Vancouver, including West Vancouver, North Vancouver, the Tri-Cities area, Pitt Meadows, and Maple Ridge. According to meteorological forecasts, these northern sections of Metro Vancouver could receive between 50 to 70 millimetres of rain starting Saturday and continuing into Sunday.
Howe Sound and the Sea to Sky Highway from Squamish to Whistler are also under the rainfall warning, while Vancouver Island faces even more substantial precipitation. Environment Canada has specifically warned that West Vancouver Island, north of Tofino, could see between 80 to 100 millimetres of rainfall.
Timeline and Weather System Movement
The precipitation pattern will begin with light rain or drizzle before intensifying to periods of heavy rain later on Saturday. The system is expected to ease early Sunday morning as it moves through the region.
Environment and Climate Change Canada emphasizes that water will likely pool on roads and in low-lying areas, creating potential flooding concerns. The agency also warns that visibility may be suddenly reduced at times, creating hazardous conditions for motorists and pedestrians alike.
Travel Advisories and Safety Recommendations
Weather experts are cautioning drivers that conditions in mountainous regions can change rapidly, resulting in potentially dangerous driving situations. Authorities are advising motorists to allow extra time for travel and exercise additional caution when navigating affected areas.
The rainfall warning comes as part of a broader weather system affecting much of B.C.'s South Coast, with residents advised to monitor weather updates and prepare for potentially challenging conditions throughout the weekend period.
