A powerful windstorm, combined with an atmospheric river, is poised to unleash a ‘firehose’ of intense precipitation stretching from California to British Columbia. This weather event is expected to bring heavy rain, strong winds, and potential flooding across the region, with significant impacts anticipated in coastal and inland areas. Authorities are warning residents to prepare for hazardous conditions as the storm moves northward.

Bomb cyclone has caused widespread devastation across the US West Coast, resulting in at least two fatalities and knocking out power for hundreds of thousands. The storm, characterised by rapid intensification over a short period, brought heavy rainfall and winds reaching speeds of 80 km/h (50 mph) to Oregon, Washington, and California on Wednesday. With harsh weather conditions expected to persist through Friday, the impact of this storm continues to be felt across the region.

“Back-to-back powerful Pacific storm systems to impact the West Coast through the end of this week with heavy rain, life-threatening flooding, strong winds, and higher elevation mountain snow,” the National Weather Service (NWS) predicted in a social media post.

An incredible satellite image recently showed the bomb cyclone rapidly intensifying over the Pacific Northwest, with its swift intensification clearly visible in the imagery.

 What Is Bomb Cyclone?

A bomb cyclone occurs when a storm system's atmospheric pressure suddenly drops by a significant amount, a process known as bombogenesis. This happens when pressure falls by at least 18 to 20 millibars within 24 hours, depending on the storm's latitude. The current storm is expected to drop pressure by 60 to 70 millibars over 24 to 36 hours, making it one of the fastest-deepening low-pressure systems on record, according to climate scientist Daniel Swain.

Power outages in Washington fluctuated throughout Tuesday evening, stabilising at around 460,000 by Wednesday afternoon. In Oregon, 2,800 customers were without power, while California had 38,000 outages and Nevada reported 10,000, including areas around Carson City and Reno. Several schools were closed in Seattle and Reno, and high winds led to the closure of the main highway between Reno and Carson City for semi-trucks. Additionally, all chairlifts at Mt. Rose Ski Resort near Lake Tahoe were shut down, as reported by AP.
