Rainfall Warning up to 150 mm Sunday to Monday

Environment Canada has issued a Rainfall Warning for Howe Sound. 

A Snowfall Warning is also in effect for Sea to Sky - Squamish to Whistler for Saturday night, with accumulation of up to 15 cm ahead of the rain event.

A significant atmospheric river event will bring copious amounts of rain and near record temperatures to the B.C. south coast beginning late this afternoon. As the warm front approaches, steady rain will develop late this afternoon.

Rainfall up to 150 mm for Howe Sound is expected for Sunday and Monday. Warm temperatures will accompany the rain.

Rising freezing levels with melting snow giving rise to increased river flows and localised flooding.

The rain will be heaviest Sunday afternoon and Sunday night ahead of the cold front. The heavy rain will ease on Monday as the cold front pushes the precipitation out of the region.

This could result in possible washouts, debris flow and pooling water as rising freezing levels will also melt snow at higher elevations. Local river levels will rise and river flows will increase as a result of the heavy rain.

Near record temperatures will also accompany this system.

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.
