Alert Details
Environment Canada has issued an orange rainfall warning for West Vancouver Island. This severe weather alert is in response to a prolonged atmospheric river event that is expected to bring significant precipitation and potential hazards to the region.
Affected Areas
The primary geographic region affected by this warning is West Vancouver Island. Residents in this area should prepare for hazardous conditions including localized flooding and potential infrastructure damage.
Expected Conditions
Total rainfall amounts are expected to reach between 150 to 250 mm, with localized areas potentially seeing up to 300 mm. Because freezing levels are forecasted to remain high—between 2,000 and 3,000 metres—heavy rain combined with mountain snowmelt is expected to significantly enhance the response of river systems.
Potential impacts include:
- Extensive water pooling on roads and possible washouts.
- Increased risk of landslides in vulnerable areas, such as steep slopes, deforested regions, or recent burn scars.
- Rapidly rising water levels in rivers and streams that can sweep away vehicles and damage infrastructure.
Timeline
The atmospheric river is expected to remain over the South Coast of B.C. through Friday.
- Sunday to Wednesday morning: Initial heavy rainfall period.
- Wednesday morning: Rain is expected to briefly ease.
- Wednesday afternoon to Friday: Periods of moderate to heavy rain will continue.
- Thursday night to Friday morning: The heaviest rainfall of the latter half of the week is anticipated.
What You Should Do
Residents are urged to monitor ongoing alerts and forecasts from Environment Canada. Localized flooding is likely, and some roads may become impassable; avoid driving through fast-moving water. To report severe weather, you can email BCstorm@ec.gc.ca or post reports on X using the hashtag #BCStorm.
