Remarkably fierce storm threatens B.C. with damaging ramifications

An extraordinary Pacific storm with explosive strengthening is en route for B.C. Sunday. This particular system may bring historic rates of intensification and depth of low pressure for the coast. Along with a rapid drop in pressure, a prolonged period of intense winds is expected, with hurricane-force strength remaining well offshore of Vancouver Island. If that weren't enough, upwards of 150 mm of rain is anticipated for parts of the coastal and inland sections through Monday. Needless to say, considerable disruptions to power and travel are likely, including the potential of ferry cancellations, and the risk of tree damage is also there. More on the weekend timing and the possible impacts, below.

SATURDAY: BRIEF BREAK BEFORE ARRIVAL OF POWERFUL PACIFIC STORM TO END WEEKEND

The weekend will start off with morning rain Saturday, but will give way to a dry afternoon and clearing overnight.

In the meantime, a potent Pacific low will rapidly intensify over the next 24 hours as it creeps closer to the B.C. Coast. The system is expected to start to weaken before reaching land, but will surely provide heavy rain and a prolonged period of blustery winds. Special weather statements are in place.

Rain will push onto the coast Sunday morning, while the winds will ramp up in the evening.

As the low pressure system moves closer Sunday night, the strong winds will strengthen over the inner South Coast on 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 Islands (Comox to Campbell River), possibly impacting ferry services. Forecasters are also warning people to brace for possible tree damage and power outages.

"As of now, there is good confidence for the strongest winds to be over West Vancouver Island and that the low pressure system will track across northern Vancouver Island on Monday. Wind warnings for most of the south coast will likely be issued later today," Environment and Climate Change Canada said in the special weather statement.

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 is 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: STORMY PATTERN HANGS ON, EXCESSIVE SEVEN-DAY RAIN TOTALS

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.
