Metro Vancouver Braces for 'Bomb Cyclone'!

Metro Vancouver is gearing up for a tumultuous week of weather, with a "bomb cyclone" set to unleash its fury across the region starting Tuesday, November 19. This meteorological phenomenon, characterized by its rapid intensification, is expected to bring fierce winds that could wreak havoc on the Lower Mainland.

Meteorologist Insights

According to Environment Canada Meteorologist Brian Proctor, this bomb cyclone is “very impressive” as it gathers strength over the Pacific Ocean. The weather system is fed by cold air that previously contributed to Sunday’s rare hailstorm and thunder, indicating that locals should prepare for potentially violent weather.

Origin and Impact of the Cyclone

Unlike the hailstorm, this weather event originates from a low-pressure system moving south from the Gulf of Alaska. Defined by a drop of over 24 millibars in 24 hours, this rapid cyclogenesis can cause severe weather disruptions. While rainfall will occur, it’s unlikely to reach the extreme totals associated with atmospheric rivers. Instead, residents should brace for strong winds, with gusts predicted to range from 70 to 90 km/h.

Power Outages and Emergency Preparedness

Proctor warns that this sizable wind event is expected to lead to substantial power outages throughout the area. “The duration of these outages could be fairly extensive,” he commented, and with BC Hydro known for longer restoration times during such storms, it's advisable for residents to prepare an emergency kit that can sustain them for at least 72 hours.

Storm Timing and Expectations

The storm is projected to hit overnight into Tuesday afternoon, with low temperatures raising the possibility of hail or even freezing rain. As the cyclone begins to dissipate heading into Wednesday, another front is anticipated, though Proctor notes this subsequent system won’t be as powerful.

Continuing Weather Challenges

But the stormy pattern won’t end there! A third wave of inclement weather is expected to roll into the Lower Mainland from the Gulf of Alaska about 24 to 36 hours after the second system, meaning residents should remain alert and ready for continued challenges.

Stay Informed and Prepared

With the potential for widespread disruptions, including power outages and hazardous road conditions, it’s essential to stay informed and prepared. Take the necessary precautions now, as Metro Vancouver sets itself into what promises to be an intense week of stormy weather. Stay safe, everyone!
