The day after a powerful winter storm led to school cancellations, power outages and traffic nightmares on Vancouver Island, Environment Canada is warning British Columbians that the weather is about to get worse before it gets better.

The agency has issued a winter storm warning for B.C.’s South Coast including Greater Victoria, east and inland Vancouver Island and the Southern Gulf Islands. The advisory was first issued as a storm watch, but was upgraded to an official warning later in the day. 

A Pacific warm front was expected to arrive late Wednesday, bringing five to 15 centimetres of snow with a “good chance” of freezing rain, followed by significant rainfall on Thursday.

That could create slick, icy conditions on roadways making travel difficult in some areas, according to Environment Canada.

Flooding is also a concern in low-lying areas, the agency said.

“If you see freezing rain, most of that will be through inland Vancouver Island, and then there’s a transition to milder conditions,” said CTV Vancouver Island Meteorologist Astrid Braunschmidt. “It’s going to be a bit of a wintry mess, a mix, until Thursday.”

Classes and flights were cancelled up and down the island Monday after the first round of the storm blanketed cities with heavy snowfall.

Power lines were affected in multiple areas, and BC Hydro said “pocket” power outages would continue to be experienced in some areas of Duncan and on Cortes Island throughout the day Tuesday.

All planned power outages were cancelled for the remainder of the week so crews could be better prepared for any fallout from the latest storm.
