Special weather statement issued for the Sea to Sky and Howe Sound

Nov 24, 2021
Affected Communities: 
District of Squamish, Electoral Area C, Electoral Area D, Resort Municipality of Whistler, Village of Pemberton

Howe Sound and Lower Mainland

Another round of heavy rain is on the way for Howe Sound and the Lower Mainland (total rainfall 50 to 80 mm) starting tonight and through to Thursday. Expect strong southeast winds near the water on Thursday.

Remarks: This storm will be shorter lived and less intense than the event over November 13-15, 2021. However, it will still bring moderate to heavy rain and strong winds. Additionally, freezing levels will rise above mountain tops on Thursday. This may worsen recent flooding and impact vulnerable landscapes and infrastructure. Localized flooding in low-lying areas is possible. Heavy downpours can cause flash floods and water pooling on roads.

Don't approach washouts near rivers, creeks and culverts.


Whistler and the Sea to Sky

Expect potentially heavy snowfall followed by rain for Whistler and the Sea to Sky Highway north of Brandywine.

Total snowfall: up to 15 cm
Total rainfall: up to 20 mm.
Timespan: Tonight through Thursday.

Remarks: The next storm system is set to arrive on the B.C. south coast tonight. The Sea to Sky corridor north of Squamish may see heavy wet snow of up to 15 cm through Thursday, before freezing level rises during the day Thursday. The wet snow will then change to moderate to heavy rain before ending Thursday night. This may impact the already vulnerable landscapes and infrastructure.

There are some uncertainties on the forecasted snowfall and rainfall amounts, and when the snow will change over to rain. Please continue to monitor local forecasts and alerts for the latest information.

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.
