Deep Look

This week, a powerful storm system classified as a “bomb cyclone” wreaked havoc across the northwestern United States, delivering a punishing combination of torrential rain, hurricane-force winds, and heavy snowfall. The storm, intensified by a potent atmospheric river, left a trail of destruction from Washington to California and eastward into the Dakotas. This storm event is among the most severe of the season, with weather warnings and emergency declarations spanning multiple states.

Rainfall and Flooding Threats

The atmospheric river brought extreme rainfall, with forecasts predicting up to 16 inches in southwestern Oregon by Friday. Northern California also braced for over 10 inches of rain, with flood watches extended through Saturday for areas north of San Francisco. Officials warned of significant risks, including flash flooding, rock slides, and debris flows, particularly in areas with burn scars or steep terrain. These conditions could devastate communities and infrastructure in vulnerable regions.

Heavy Snow and Mountain Hazards

In higher elevations, snowfall reached record levels, with the northern Sierra Nevada and Cascades experiencing near-blizzard conditions. Snowfall accumulations of up to 15 inches were reported above 3,500 feet in the Sierra Nevada, accompanied by wind gusts exceeding 75 mph. Forecasters cautioned against travel through mountain passes, warning of whiteout conditions and rapid snow accumulation rates of up to 3 inches per hour.

Northern California saw heavy, wet snow creating dangerous travel conditions and threatening structural collapses. Meanwhile, in the Dakotas and Minnesota, the first significant snowfall of the season caused road accidents and travel delays. North Dakota’s Turtle Mountains were projected to receive as much as 16 inches of snow, while areas like Minot prepared for up to 8 inches. Gusting winds reaching 60 mph compounded the hazards, particularly in open areas like Montana and Nebraska.

Lives Lost in Washington State

The storm turned deadly in Washington, where fierce winds caused trees to fall on homes and encampments. In Lynnwood, Washington, a woman was killed Tuesday night when a large tree toppled onto a homeless encampment. Another fatality occurred in Bellevue when a tree crashed into a residence. Firefighters and first responders worked tirelessly to address emergencies, including rescuing individuals trapped by debris.

Tracy Meloy, a resident of Issaquah, Washington, described her neighborhood as a scene of destruction, with tree limbs, leaves, and debris covering the streets. “It looks like a forest floor instead of a street,” she observed after venturing out to assess the storm’s aftermath. The damage left many residents without power and roads blocked by fallen trees.

Power and Infrastructure Disruptions

Nearly 460,000 homes and businesses in Washington were without power by Wednesday afternoon. Oregon reported 2,800 outages, California over 38,000, and Nevada nearly 10,000. High winds and hazardous conditions led to the closure of schools across the region, including three in Reno, Nevada, where high winds also forced the shutdown of main highways between Reno and Carson City. Chairlifts at the Mt. Rose Ski Resort near Lake Tahoe were grounded due to unsafe conditions.

Interstate 5, a vital transportation corridor, was closed for an 11-mile stretch from Ashland, Oregon, to the California border due to severe winter weather. Authorities described the closure as long-term, with no immediate timeline for reopening. In northwestern Washington, ferry services between Port Townsend and Coupeville were suspended due to rough seas and high winds, further disrupting regional travel.

Midwest and Alaskan Impact

The storm’s influence stretched eastward into the Dakotas, Minnesota, and Montana, where icy roads caused accidents and disruptions. In northern Minnesota, state troopers responded to multiple crashes, including jackknifed tractor-trailers on Interstate 94. The National Weather Service advised against travel in parts of northern North Dakota due to treacherous conditions.

Even in Alaska, the storm contributed to high winds in Juneau, where gusts reached 60 mph, prompting local advisories. The breadth and intensity of the storm underscored its far-reaching impact, affecting millions of people across the western and central United States.

Ongoing Concerns and Precautions

Officials urged residents across the impacted regions to remain vigilant. The National Weather Service posted warnings about the dangers of falling trees during high winds and advised people to stay in interior rooms and avoid windows. Travel remained hazardous in many areas, with authorities urging caution and preparedness.

For residents like Robert and Lisa Haynes of Issaquah, Washington, the storm transformed their neighborhood into an unrecognizable landscape of blocked roads and scattered debris. “It’s like a snow day,” Robert Haynes noted, “but with no snow.”
