A powerful “bomb cyclone” is wreaking havoc across the northwestern United States and western Canada, triggering heavy rainfall, strong winds, and significant snow in a region where over seven million residents are feeling the impacts. This rapidly intensifying storm, characterized by a sudden drop in air pressure near the coast, has sadly been linked to at least one fatality—a woman near Seattle who lost her life when a tree collapsed onto a homeless encampment in Lynwood.
The destructive storm has caused widespread power outages, leaving more than 600,000 homes in Washington without electricity as of Wednesday morning, while an additional 15,000 customers in California also faced disruptions. In light of falling trees damaging homes and blocking roads, local emergency services have advised residents to seek shelter in the lowest level of their homes and avoid venturing outside if possible.
As weather conditions persist, Washington face closures and disruptions in schools. The storm’s impact extends to northern California, with the US Weather Prediction Center warning of excessive rainfall leading to flash flooding and potential mudslides, particularly in the San Francisco Bay area where up to 8 inches (20 cm) of rain are anticipated.
Additionally, Canada is not spared, as wind gusts of up to 100 mph (160 km/h) have been reported off the coast of Vancouver Island, resulting in approximately 140,000 outages. While winds are expected to ease, blustery conditions will continue, and heavy rain will blanket much of the Pacific coast through Thursday and Friday.
Forecasters are also preparing for a series of challenges stemming from the storm, which could include flash flooding, rock slides, and significant debris flows. The moisture-laden storm is projected to release heavy mountain snow, especially in the Cascade Range, which stretches across both the US and Canada.
As milder air approaches at the end of the week, the heavy snow currently blanketing the Cascades and North Rockies is likely to start melting. This, combined with further rain, raises concerns for severe flooding and landslides from Northern California to Oregon as the week concludes.
Despite the challenges posed by this powerful storm, communities are banding together to support those affected, demonstrating resilience and solidarity in the face of adversity. Emergency services and local authorities are coordinating response efforts to ensure safety and provide assistance where needed. This event serves as a reminder of the unpredictable nature of weather and the importance of community preparedness and support.
