Rainfall Warning

Issued at 04:32 Saturday 27 November 2021

Heavy rain this weekend.

Total Rainfall: 100 to 130 mm.

Locations: West Vancouver Island.

Timespan: Now to Sunday afternoon.

Remarks: Another front will approach the south coast on today. Rain has begun and will intensify during the day. Heavy rain will start to ease late Sunday morning. Total rainfall amounts exceeding 100 mm are expected through the period with southwestern regions receiving even higher amounts. Port Renfrew may see up to 130 mm.

Strong warming will accompany this system causing freezing levels to rise well above the mountain tops today. Snowmelt will contribute to runoff, increasing the risk of flooding and possibly impacting vulnerable landscapes and infrastructure.


Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #BCStorm.
