Back-to-back storms in B.C. have potential for damaging impacts

On the heels of Friday's strong storm, a second Pacific system began pushing into Vancouver Island Saturday evening, and is set to continue Sunday. This will bring another round of high-elevation snow, strong, potentially damaging winds and rain. That won't be the end of the storm track, or the worst of it, however. A third, even more potent low, will move onto the coast Monday afternoon with a higher likelihood of having damaging impacts including power outages. For a closer look, see below.

WEATHER HIGHLIGHTS:

  • Next system continues into Sunday, with strong winds, rain and high-elevation snow

  • Round three beckons for Monday evening, expected to be a more impactful storm, possibly damaging, power outages possible

  • Unsettled weather continues next week

SUNDAY: NEW SYSTEM BRINGS IN MORE SNOW, WINDS, RAIN

The latest system to impact British Columbia has featured strong winds once again, though the peak is likely to be the overnight hours Saturday into Sunday, with 70-90 km/h gusts not out of the question, and the Fraser Canyon possibly 100 km/h by the pre-dawn hours. Wind warnings are in effect for eastern Vancouver Island and Victoria.

This next Pacific storm will also bring more heavy snow to the highway passes. Snow will continue through Sunday evening. Some areas could see another 25-35 cm of snow. Winter storm warnings are in place for the Coquihalla Highway - Hope to Merritt region.

"Prepare for quickly changing and deteriorating travel conditions. Visibility may be suddenly reduced at times in heavy snow," Environment Canada says in the warning "Weather in the mountains can change suddenly resulting in hazardous driving conditions."

Meanwhile, the system will materialize as rain for the lower elevations across the coast and Lower Mainland. Nothing too spectacular for B.C. standards, but parts of Vancouver Island and the Lower Mainland are in line to get 20-40 mm through Sunday.

MONDAY/TUESDAY: POTENTIAL DAMAGING STORM

Following that system's departure, forecasters are keeping an eye on yet another moisture-laden system moving in Monday evening. This low will bring similar effects as the previous two, but is expected to have a more widespread impact. It will yield heavy snow for the mountain passes, strong, potentially damaging winds, and heavy rain.

The strongest winds will occur Tuesday morning and afternoon for west Vancouver Island, the afternoon and evening through the straits and across the Lower Mainland. Gusts along coastal areas of western Vancouver Island will hit 80-110 km/h, 70-90 km/h along southern portions and the straits, and 70-80 km/h across the Lower Mainland. The winds will shift to a southwesterly direction in the evening.

Because the system is in the long-range time frame, there is still some uncertainty regarding the exact track and intensity. However, even if the low tracks a little farther south, there will be significant impacts to travel and electricity, with the likelihood of downed trees and power lines.

More rounds of snow are expected for the southern Interior next week, along with some rain, with very impressive snow totals for the Rockies and Kootenay Mountains. In addition to the wet weather, frigid weather dominates across the northern half of B.C. next week.
