Environment Canada warns of up to 80 mm rain Friday on B.C.’s South Coast. Heavy downpours may trigger flooding and dangerous water levels.
B.C.’s South Coast Faces Torrential Rain Friday
Environment Canada has issued a rainfall warning for Metro Vancouver, Howe Sound, and the Sunshine Coast. The alert predicts up to 80 millimetres of rain in 24 hours, with the heaviest precipitation in higher elevations.
Unseasonable Weather System Driving the Storm
According to Christy Climenhaga, scientist with Environment and Climate Change Canada, the downpour will be caused by an unusual, moisture-laden Pacific frontal system. She said this amount of rainfall is rare for August and will arrive in a short period of time.
When the Heaviest Rain Will Hit
Rain is expected to intensify Friday afternoon, delivering 50–80 mm in most areas and up to 80 mm at higher altitudes. Environment Canada warns of possible flash flooding and roadway pooling during peak hours.
Communities Under the Rainfall Warning
Areas affected include Bowen Island, Coquitlam, Gibsons, Maple Ridge, North Vancouver, Squamish, and West Vancouver. Residents in elevated terrain are likely to experience the highest rainfall totals.
Flood and Streamflow Risks
The B.C. River Forecast Centre has issued a high streamflow advisory for the South Coast, including Howe Sound, Sea to Sky, and Pemberton regions. Rivers, creeks, and low-lying areas may see rapidly rising water levels, posing hazards to campers and drivers.
Safety Advice for Outdoor Activities
Squamish Search and Rescue is urging caution. Spokesperson Christy Allan warns that heavy rain and low cloud can hinder rescue operations, and river levels may surge unexpectedly. She recommends delaying outdoor trips and calling for help early if trouble arises.
Storm Expected to Ease by Late Friday
Environment Canada expects rainfall to taper off late Friday along the Sunshine Coast and after midnight in Metro Vancouver. Officials advise residents to monitor weather alerts and plan travel or outdoor activities accordingly.
