B.C. coast braces for high winds, power outages, travel disruption as ‘bomb cyclone’ forms in Pacific

A bomb cyclone is currently forming off the coast of Vancouver Island, with forecasters warning of hurricane-level wind gusts. The storm is expected to bring easterly winds of up to 120 km/h, causing potential power outages and disruptions to transportation.

The term “bomb cyclone” refers to a rapid pressure drop of over 24 millibars within 24 hours. The storm, located 400 kilometers west of Tofino, B.C., is expected to see a pressure drop of 60 millibars over a 24-hour period, a highly unusual occurrence for the region. Forecasters predict that the storm’s central pressure could be comparable to that of a Category 3 or 4 hurricane.

The North Coast is expected to experience the strongest winds, with gusts reaching up to 150 km/h. B.C. Ferries has issued a travel advisory in anticipation of the storm, with several sailings already cancelled. Armel Castellan, a meteorologist, emphasizes the need for vigilance as the storm brings strong winds in a new direction that could test the resilience of power cables and transmission lines.

In addition to strong winds, the bomb cyclone will bring rain and snow to coastal B.C. Higher elevations could see nearly a meter of snow by Wednesday night. The storm is the second major windstorm to hit B.C.’s South Coast in a week, following one that caused tens of thousands of properties to lose power.

Concerns for ships in the region have prompted warnings for vessels to avoid the area, with the entire West Coast of North America expected to be affected. Communities are preparing for potential power outages, with emergency preparedness programs advising residents to have emergency kits and power outage plans in place.

PreparedBC is reminding British Columbians to be prepared for the storm, while communities on Vancouver Island are taking steps to ensure safety and minimize disruptions. Road closures and backup generators are being prepared, with crews standing by to address any issues that may arise.

As the storm approaches, drivers are urged to check road conditions and ensure their vehicles are equipped with winter tires or chains. The Ministry of Transportation and Transit advises caution and preparedness when traveling in potentially hazardous conditions.
