Coastal B.C. urged to brace for strong winds as ‘bomb cyclone’ develops offshore

People living in British Columbia’s coastal areas are being advised to prepare for a powerful fall storm.

A powerful low-pressure centre has parked off the B.C. coast, and, with its pressure expected to continue falling, is forecast to generate intense easterly winds throughout Tuesday.

“Over the next 24 hours, we are going to see a really rapidly intensifying storm offshore — and that’s the big operative point here, is that the storm is going to come towards the coast, and then get 350-400 kilometres away,” explained Environment Canada warning preparedness meteorologist Armell Castellan.

“So it is going to get close enough to give us some really strong winds southeasterly for areas in the Salish Sea, and then north for Howe Sound, Fraser Canyon.”

Environment Canada has issued wind warnings for Vancouver Island, Howe Sound, the Sunshine Coast and the Southern Gulf Islands and the North and Central coasts.

Special weather statements are also in place for Metro Vancouver and the Fraser Valley along with much of the central interior.

Winds could gust up to 110 km/h on Vancouver Island’s west coast, while Greater Victoria and eastern Vancouver Island could see gusts in the 90 to 100 km/h range. The North Island and mainland inlets on the central coast could see winds gust up to 120 km/h.

Gusts in Metro Vancouver could reach about 78 km/h.

“There is going to be flying debris all over the place, 100, 110, even 120 km/h gusts are possible on the north tip of Vancouver Island,” Castellan said.

“That will be enough to dislodge loose items and send them flying. In fact, BC Hydro had one event just a couple of weeks ago where flying patio equipment caused 14,000 people to lose power because it damaged one of their pieces of equipment.”

BC Hydro spokesperson Kevin Aquino-Bravo said the Crown corporation has been gearing up in anticipation of the storm.

“We did alleviate some crews this morning so we would have a full complement of crews overnight, and that would ensure we have a strong response in the event the bomb cyclone does materialize,” he said.

“One thing we did do is we put some crews onto the ferries this morning to get to the hard-to-reach areas so we would have restoration services in places like the North Island.”

The winds are forecast to peak Tuesday night.

This type of system is known as an explosive cyclogenesis, a bomb cyclone or a bombogenesis.

It occurs when a rapid drop in atmospheric pressure is recorded at the centre of a storm system.

B.C.’s emergency management ministry has issued an advisory of its own, urging people to be prepared for the conditions, including being ready for power outages and having an emergency kit handy.

Meanwhile, B.C.’s South Coast saw its first taste of snow for the season on Monday night.

Flakes were recorded falling and sticking on Burnaby Mountain and in parts of Surrey, Coquitlam and Aldergrove.

While the snow had melted by Tuesday morning, municipal snowplows were out in several areas overnight.
