Metro Vancouver Faces Storm Surge Warning and Potential Flooding
Environment Canada has issued a storm surge warning for British Columbia, signaling wetter, windier, and colder conditions ahead.
Weather Outlook for Metro Vancouver
The region, including Metro Vancouver, will soon experience increased rainfall after a relatively dry fall. This shift toward late fall and early winter brings typical B.C. rainfall and a storm system that could cause flooding.
Storm Surge Details
Higher than normal ocean water levels are expected along the Vancouver Island coastline. Environment Canada states:
“Elevated ocean water levels accompanied by significant winds and waves are expected, possibly exceeding highest astronomical tide.”
Affected Areas and Expected Precipitation
- Metro Vancouver areas such as Ladner and Tsawwassen may see 20 to 30 mm of precipitation.
- The North Shore, Port Coquitlam, and Port Moody could experience 40 to 70 mm of rainfall.
Additional Weather Factors
An incoming frontal system will bring strong southeast winds in the afternoon. The alignment of peak southeast winds with high tide may cause water levels higher than usual astronomical tides, increasing the risk of a storm surge.
“The timing of the peak southeast winds with high tide will result in potential storm surge with water level higher than the astronomical tide.”
Summary
Residents in and around B.C. should prepare for possible flooding and challenging weather conditions in the coming days.
