Potent lows bring heavy rain, snow to B.C., avalanche risk raised

Another soggy weekend is in store for B.C. with back-to-back Pacific lows moving onshore with heavy rain for the coastal sections and copious snowfall for the alpine regions. The next bout will begin Saturday afternoon. Some areas in western Vancouver Island may see 100+ mm of rain through Monday, while some of the mountain passes may receive 30+ cm of snow. The amount of snowfall expected has prompted a special avalanche warning for parts of the coastal mountains. For a deeper look, see below.

WEATHER HIGHLIGHTS

  • Light rain lingers Saturday morning, next low moves in late afternoon

  • Rounds of rainfall, alpine snow persists to Monday

  • Rainy at the coasts, but very heavy snow in the mountains, avalanche warnings in effect

SATURDAY/SUNDAY: COASTAL RAIN, HEAVY SNOW IN THE MOUNTAINS

A Pacific front will continue to bring light rain Saturday morning for the Lower Mainland and coastal Vancouver Island. Heavier rainfall will develop in the late afternoon, with the next system moving onshore, continuing into the evening hours. Another round of rain will trek in with yet another low on Sunday.

Because freezing levels won't be near sea level, unlike what transpired earlier this week, lower elevations of the coastal region will see rain. Amounts will vary in the coming days, with parts of western Vancouver Island in line for totals in the 100+ mm range. As you head into the Lower Mainland, some areas could see 30-50 mm through Monday.

Snowfall will continue to fall in the alpine regions throughout Saturday.By the afternoon, parts of the southern Interior, including some mountain passes, will see snow spread across the region. The high-elevation snowfall continues Sunday and Monday, and will be heavy at times, as the active pattern continues.

Accumulations of 30+ cm of snow is possible for some routes, from the Paulson Summit to Kootenary Pass. There are several Pacific lows coming onshore, one after another over the next few days.
