Metro Vancouver Faces Storm Surge Warning and Potential Floods
Environment Canada has issued a storm surge warning for British Columbia, alerting residents to the risk of flooding in several regions. The weather is expected to turn significantly wetter, windier, and colder over the coming days.
After a relatively dry fall, temperatures are dropping, signaling the return of the typical B.C. rainfall as the area moves into late autumn and early winter. This shift is being accompanied by a strong coastal storm.
Expected Impacts
Higher-than-usual water levels are forecast for the Vancouver Island coastline. These conditions, paired with powerful winds and waves, could lead to a storm surge.
“Elevated ocean water levels accompanied by significant winds and waves are expected, possibly exceeding highest astronomical tide.” — Environment Canada
Rainfall and Wind Forecasts
- Metro Vancouver communities such as Ladner and Tsawwassen may receive 20–30 mm of rain.
- The North Shore, Port Coquitlam, and Port Moody could see between 40–70 mm of rainfall.
- Strong southeast winds are expected during the afternoon frontal system, aligning with high tide and increasing the risk of flooding.
“The timing of the peak southeast winds with high tide will result in potential storm surge with water level higher than the astronomical tide.” — Environment Canada
Residents across coastal and low-lying areas of B.C. are advised to monitor weather alerts and prepare for possible flooding due to the combination of high tides and heavy precipitation.
