The 'cone of uncertainty' over where to expect the worst impacts of an incoming fall storm in B.C. has narrowed somewhat, and it now looks like the storm's heaviest impacts will remain south of the province. Still, it will be responsible for some hefty winds at the coasts, along with some heavy snows in the mountain passes to close out the week, into the weekend. For a closer look, read on.

WEATHER HIGHLIGHTS:

  • Fall storm impacts southern B.C., worst impacts to stay in Washington State

  • Strong winds at the coasts, peaking later Friday

  • Heavy snow at the mountain passes into Saturday

FRIDAY INTO SATURDAY: LESS UNCERTAINTY OVER STORM TRACK

As this system slowly approached the northwestern part of our continent over the past few days, forecasters struggled to pin down where it would impact the hardest. On Thursday, however, things became more clear, and it now looks like its strongest effects will remain south of B.C.

However, that's not to say it won't have any impact at all. The system will begin to bring some rain Friday morning, but the winds, funnelled through the Strait of Georgia, will be picking up through the afternoon, peaking in the evening in the 50-70 km/h range. Ferry delays or cancellations will not be out of the question, and some power outages are possible as well.

In the mountains, freezing levels will drop to 700 metres Friday and 500 metres Saturday, bringing more snow to the highway passes, as much as 5-15 cm for the lower passes, and in the 30-40 cm range for the Coquihalla through Saturday.

Significant amounts are also possible at the lower elevations and the valleys of the Interior as well, likely to impact travel through the mountain passes. Substantial snow is also likely for the North Shore ski areas, as well as Whistler.

BEYOND: EYES ON THE NEXT MOISTURE-LADEN SYSTEM

Conditions will begin to improve through the day Saturday, and a bit of a break is ahead for Sunday, but forecasters are keeping an eye on another moisture-laden system for Monday. Once again, there's some uncertainty in that storm's track and impacts as it moves in from the southwest.

"If the track stays further to the west, then very mild air will surge in aloft – bringing heavy rain to the alpine areas," Weather Network meteorologist Dr. Doug Gillham says. "However, if the track is further to the east, then cold air will remain in place with snow for the ski areas."

Regardless of how it shakes out, Gillham says cooler than seasonal temperatures are expected for the middle and end of next week.
