Storm parade to send in multiple coastal systems to B.C. with rain, snow

Must read

After this week’s windstorm that led to significant power outages, and even shaking the ground with a 108 km/h gust in Victoria, more foul weather is on the way as an active pattern sets up in coastal B.C. over the next eight to 10 days.

Models are indicating that coastal B.C. will be the wettest part of the country for the next eight to 10 days. We are tracking more than three low-pressure systems as the jet stream aligns with coastal sections of B.C.

This week and beyond:

An onshore flow that is from the west or northwest over the short and long range will bring a new system to coastal B.C. every other day. Heavy amounts of moisture will be associated with these waves of moisture over the next 10 days.

Freezing levels will be dropping, so heavy amounts of alpine snow will be expected to start off the ski season, and snow will also be expected across parts of the mountain passes.

That will bring copious amounts of rain along coastal B.C., and some for the Rockies, too, but lesser totals.

  • Vancouver: 175 mm

  • Victoria: 146 mm

  • Kelowna: 25 mm

With the rain that has fallen, and the forecast amount over the next two weeks, that will most likely push some places in B.C. to above their normal amount of precipitation.

The active storm track over the next couple of weeks can be highlighted as the jet stream brings continuous systems to the B.C. coast due to a high-pressure system situated well southwest of the province over the Pacific Ocean.
