Metro Vancouver Faces Storm Surge Warning and Potential Floods
Environment Canada has issued a storm surge warning for British Columbia, signaling the arrival of wetter, windier, and colder weather with possible flooding in some areas. After a relatively dry fall, rain is expected to increase as temperatures drop, marking the transition to late fall and early winter conditions.
Storm Surge Details
The Vancouver Island coastline will experience higher than normal water levels. Environment Canada explains:
“Elevated ocean water levels accompanied by significant winds and waves are expected, possibly exceeding highest astronomical tide.”
This phenomenon is identified as a storm surge, which may cause flooding in low-lying coastal zones.
Affected Areas and Rainfall Forecast
- Metro Vancouver neighborhoods such as Ladner and Tsawwassen could receive 20 to 30 mm of precipitation.
- The North Shore, Port Coquitlam, and Port Moody may experience heavier rainfall in the range of 40 to 70 mm.
Additional Weather Patterns
An additional frontal system will arrive in the afternoon, bringing strong southeast winds. Environment Canada warns:
“The timing of the peak southeast winds with high tide will result in potential storm surge with water level higher than the astronomical tide.”
Residents in and around British Columbia are advised to remain vigilant due to these forecasted conditions.
