Heavy Rainfall warning for Howe Sound Saturday through Sunday

Environment Canada has issued a Rainfall Warning for Howe Sound. A warning for strong southeast winds near the water on Thursday is also in effect for Howe Sound.

Another front will approach the south coast on Saturday. Rain will begin near noon on Saturday for most areas, but the heaviest rain will be Saturday night as the front nears. Rain will start to ease Sunday afternoon.

Rainfall amounts for this event will vary from about 60 mm from Vancouver to 80 mm in the Fraser Valley to 100 mm closer to the mountains. Squamish may see up to 120 mm. Gibsons will also receive 60 to 80 mm of rain.

For the Sea to Sky highway, precipitation will start as light snow north of Brandywine on Saturday and transition to heavy rain Saturday afternoon. Rainfall amounts of 50 mm are expected by Sunday evening.

Strong warming will accompany this system causing snow levels to rise well above the mountain tops on Saturday. 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. Watch for possible washouts near rivers, creeks and culverts.

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