After an extremely dry and hot summer for parts of B.C., the province got doused with some substantial rainfall from a powerful fall-like system Friday. Totals through the overnight hours resulted in disruptions to travel and winds bringing power outages to thousands. In fact, Vancouver International Airport recorded its wettest day Friday since January 2019. The good news is that the rain and winds will begin to subside Saturday, but will still be hanging around. That is not all, heavy snow is falling at higher elevations and on some mountain passes, so travellers need to check the road conditions before venturing out. More on the impacts of this powerful system, what is left of it, below.

SATURDAY/SUNDAY: RAIN, WIND CONTINUE, BUT WILL EASE OFF
B.C. has seen some substantial rainfall amounts in in the last 24 hours. According to Environment and Climate Change Canada (ECCC), some of the heaviest totals were:
Port Mellon: 116
Pam Rocks: 84.2
Vancouver Harbour: 75.8
West Vancouver: 86.7
Pitt Meadows: 77
North Courtenay: 55.9
Abbotsford Airport: 58.7
Delta Burns Bog: 53.9
Vancouver International Airport: 50.9
The airport saw its most rainfall in a single day since Jan 3., 2019, when 54.8 mm was recorded.
Moisture-laden frontal system will remain on the South Coast. While the worst of the rainfall has occurred, precipitation will remain steady as the potency of it continues to diminish Saturday.
Some areas could see enhanced totals as isolated, non-severe thunderstorms may bring locally heavy rainfall in the afternoon.
Additional rainfall totals of 25-50 mm are possible for parts of the Lower Mainland through Sunday, 20-30 mm elsewhere and 10-30 mm on parts of southern Vancouver Island, as well.
Winds won't be nearly of a problem as they were on Friday, cutting electricity to thousands of customers on Vancouver Island and the Lower Mainland. Some power has been restored, but thousands remain in the dark as of Saturday morning.
Still, gusts of 70-90 km/h are expected to continue in parts of the Lower Mainland and Vancouver Island before easing off Saturday afternoon.
Meanwhile, higher elevations at the Coastal and Interior mountains will see more heavy snowfall Saturday, potentially having considerable impact on some highway passes.
Sunday will see light rain continue for the Lower Mainland through the day on Sunday, as snowfall persists at alpine levels for the coastal and southern interior mountains.
Beyond the weekend, scattered showers are possible on Monday, with a higher threat for showers again on Wednesday, but overall it will be a drier week.
Cool conditions early in the week, then warming up for the second half.
