Tens of thousands without power, ferries cancelled after 'bomb cyclone' batters B.C. coast

Tens of thousands of people, primarily on Vancouver Island, were without power overnight after hurricane-force wind gustsfrom a "bomb cyclone" system blasted southwest British Columbiaon Tuesday night and into Wednesday.

Gusts of nearly 160 km/h wererecorded at the Sartine Island weather station just off the coast of northern Vancouver Island, as the storm brought down trees and power lines across the South Coast.

As of 6 a.m. PT on Wednesday, almost 90,000B.C. Hydro customers on Vancouver Island were still without power. That number was as high as 150,000 on Tuesday.

Most ferry routes, including major routes between Vancouver and the Island have cancelled their first round trips on Wednesday,said Jeff Groot with B.C. Ferries.

A 'bomb cyclone' that brought wind gusts of up to 160 km/h to parts of the B.C. South Coast led to highway closures and power outages affecting thousands of people Tuesday night.

"They make these decisions based off a couple things: wind speed, wave height, and really, at the end of the day, is it safe," said Groot.

He said the company is speaking with Environment Canada around9 a.m. PT for an update to determineif further cancellations are required.

B.C. Ferries is advisingtravellers to check itsservice noticespage prior to travel.

Meanwhile, Langara College in Vancouver said it hadclosed all classes and services on its West 49th Avenuecampus until at least noon Wednesday, due to fallen trees and disrupted power lines.

High winds could last up to 20 hours

The "bomb cyclone" system sent outflow winds roaring through B.C.'s coastal valleys, triggeringwind warnings across the coast and special weather statements far inland on Tuesday.

A cyclone is the term used when masses of warm and cool air collide to create spiralling winds, while forecasters saythe "bomb" portion of the name refers to arapid pressure dropof over 24millibars(the unit used to measure air pressure) in 24 hours. In this case, the bomb cyclone formed around 400 kilometreswest of Tofino, B.C.

"It's a very widespread wind event, which is part of the problem, but also very long lasting," said CBC science communicator Darius Mahdavi on Tuesday evening.

"Where usually a wind event like this might last six to 10 hours, this one'sgoing to last anywhere from 12 to 20 hours across parts of the coast."

Meteorologists predicted the storm would be accompanied by rainand snow, with Mahdavisaying higher elevations in some areas could get nearly a metre of snow by Wednesday night.

A bomb cyclone is forming off the coast of B.C. But is it really as dramatic as it sounds?

Downed lines, highway closures

"The Island was hit extremely hard," Ted Olynyk with B.C. Hydro toldCBC's On The Islandon Wednesday morning.

He said the utility, anticipating ferry cancellations, brought crews over from Vancouver on Tuesday night to help, and will bring more over when they can.

Videos posted online show a number of trees falling onto power lines. Olynyk is warning people who come across downed lines to stay far away.

"Always stay 10metres back, the length of a city bus," he said.

Downed trees due to strong windsclosed several highway across the province Tuesday evening. As of 6:30 a.m. PT Wednesday, a 24-kilometrestretch of Highway 4 east of Port Alberni remains closed.

Portions of highways 19, 28and 30 on the Island also remain closed, according to DriveBC.

"If you don't have to travel, don't travel. If you don't know the area, be very careful," said Tofino Mayor Dan Law on Tuesday afternoon."Make sure there's stuff in your car if you get stuck on a highway between trees ... bring water and some food."

Law said the impact of the storm was likely greater than a regular fall storm, as the strong outflow winds came from the east.

"The problem with that is that the trees are not necessarily used to that particular direction. And so they're weaker ... they strengthen themselves against the prevailing winds," he said.

The Ahousaht First Nation, located close to Tofino on the west coast of Vancouver Island, says the storm damaged structures and boats overnight, and members of the nation are waiting until daylight to check the full extent.

"This one is a lot stronger than what we had in the past," Alfred Dick, one of the nation's emergency co-ordinators, said Wednesday on CBC's The Early Edition.

Environment Canada says the strong winds are expected to gradually weaken on Wednesday.

Tuesday's storm is the second major windstorm to hit B.C.'s South Coast in a week, with one that hiton Nov. 12alsocausingtens of thousands of properties to lose power.
