Prepare for a wet and chilly Downtown Squamish Holiday Parade this Saturday, folks.
Active weather has returned, with a series of frontal systems set to push onshore today (Dec. 1) through the weekend, according to Squamish meteorologist Jason Ross.
A frontal system will bring showers to the coast and flurries for the alpine today, with the freezing near 500 metres.
Another front will move across the area this evening into Saturday morning, with rain for the coast and heavy snowfall in the mountains, with 20 to 30 centimetres of snowfall total for the Sea to Sky before the freezing level rises to nearly 1,000 metres by Saturday afternoon, Ross said.
Environment Canada has issued a snowfall warning for tonight for the Sea to Sky Highway between Squamish and Whistler.
"Rapidly accumulating snow will make travel difficult," reads the alert. "Visibility may be suddenly reduced at times in heavy snow. Weather in the mountains can change suddenly, resulting in hazardous driving conditions."
The overnight low on Dec. 1 will be 0 C.
Weatherhood predicts possible flurries or rain on Saturday afternoon. Sunset Dec. 2 will be at 4:16 p.m.
The holiday parade will jingle through town at 5 p.m.
The overnight low on Saturday will be 1 C.
The pattern will begin to shift on Sunday morning as the first of two atmospheric rivers starts to move into southwestern B.C., Ross said.
Sunday will see a high of 5 C and a low at night down to 1 C.
The second atmospheric river Monday into Tuesday is expected to be an even stronger event with freezing levels pushing to 2,200 to 2,500m with heavy rainfall, and potential river flooding with windy conditions, Ross said.
