Remarkably fierce storm threatens B.C. with damaging ramifications

Saturday, October 23rd 2021, 8:52 pm - Those in B.C. will be able to catch a short breather before the next powerful system moves in Sunday, potentially bringing damaging impacts and far-reaching disruptions from its explosive nature.

Saturday afternoon's lull will soon be replaced by the heavy rains and very strong winds of an approaching Pacific storm. The effects will begin as early as Sunday morning, peaking later Sunday through Monday. Power outages and difficult travel, including potential ferry cancellations, should be expected, along with the chance of mudslides. More on the timing and the possible impacts, below.

SUNDAY INTO MONDAY: POWERFUL STORM SET TO SLAM B.C.

People hoping for some drier conditions this weekend would have been well-served to get outdoors Saturday afternoon and evening – the next, potent storm's arrival is imminent.

This will be a strong Pacific low that has been intensifying as it nears the B.C. coast. Though it will begin weakening as it nears, it will still be not far off from peak strength – with the main threats being pounding rains and howling winds.

Wind warnings are in effect for parts of Vancouver Island, the Sunshine Coast, and Howe Sound, and forecasters warn people in the region to prepare for power outages, potential ferry cancellations, and an elevated risk of localized flooding, high swells, and landslides.

B.C. hazards

The rain will push onto the coast Sunday morning, while the winds will ramp up in the evening, ahead of the system's arrival Sunday night. From then, the strong winds will strengthen over the inner South Coast through Monday morning. Southeasterly wind gusts of 50-90+ km/h will persist from Sunday evening through Monday afternoon.

The Strait of Georgia will funnel the strongest winds towards eastern Vancouver Island (Comox to Campbell River), possibly impacting ferry services.

WATCH BELOW: A CLOSER LOOK AT WHAT TO EXPECT IN B.C.

"Loose objects may be tossed by the wind and cause injury or damage. High winds may toss loose objects or cause tree branches to break," Environment Canada said in a wind warning.

There will also be high surf and dangerous waves along the West Coast accompanying the system, lingering into Monday morning, as well.

Rainfall amounts of 100-150 mm are expected for western Vancouver Island and the North Shore Mountains while 40-60 mm is anticipated for the Lower Mainland. Localized flooding and landslides are possible in some areas.

Beyond, the stormy pattern continues for the B.C. coast through next week, with a parade of storms and an atmospheric river bringing well above normal rainfall for the South Coast of B.C., along with heavy alpine snow as freezing levels drop to 1200-1500 metres.

Rainfall totals during the next seven days will be 50-100 mm for the Lower Mainland and 100-200+ mm for the higher terrain and western Vancouver Island.
