Stormy weather kicks into B.C. with heavy alpine snow and an atmospheric river

British Columbia is entering an active weather pattern through mid-December, with above-normal precipitation expected across the province, including the South Coast.

Over the next five days, B.C. will see increased rainfall, significant alpine snow accumulation, and an atmospheric river event Sunday into Monday.

Above seasonal temperatures will dominate across most of the province through next week, but arctic air will spread into northern and northeastern areas, and attempt to spread south as we progress through mid-December.

Rounds of rain, snow, and wind to impact B.C. through the weekend and early next week

A low pressure system over the Gulf of Alaska will usher multiple weather systems onto B.C.’s coast, bringing waves of rain, snow, and gusty winds through the weekend into early next week.

After a wet Thursday, southern coastal areas will see increased rainfall beginning overnight Thursday into early Friday.

Widespread snow will impact the southern interior, with freezing levels near 1200 metres. Snow will spread into the interior and Rockies by Friday afternoon. Coastal ski resorts like Whistler Blackcomb, Sun Peaks, and SilverStar could receive 10-20 cm of snow.

Fresh snowfall will benefit the ski areas, but road conditions may pose travel challenges.

Precipitation will ease Saturday night before picking up again early Sunday as a surge of moisture delivers steady rain to the coast and additional snow to the coastal mountains.

Freezing levels will range from 1000-1200 metres along the coast and dip below 1000 metres in interior mountain ranges such as the Cariboo, Selkirk, and Purcell regions.

Risk of localized flooding early next week

This storm pattern could bring heavy rainfall Monday into Tuesday, increasing the risk of localized flooding and pooling on roads.

Travelers should prepare for challenging conditions, as passes will see accumulating snow and gusty winds reaching up to 60 km/h.
