In-Depth Analysis

The windstorm was driven by an atmospheric river pulling moisture from the Pacific Ocean. This resulted in heavy rain in Seattle and significant snowfall in the Cascades. The combination of high winds and heavy snow created near white-out conditions, particularly in mountain areas. Power outages were widespread due to downed trees and power lines. Utility crews are working to restore power, but ongoing weather conditions are hampering efforts.

**How to Prepare:**

  • Ensure you have flashlights, batteries, and a portable charger.
  • Stock up on non-perishable food and water.
  • Keep freezers and refrigerators closed to preserve food.
  • If using a generator, operate it outdoors at least 20 feet away from windows, doors, and garages.

**Who This Affects Most:**

  • Residents in Western Washington, particularly those in areas with dense tree cover.
  • Travelers attempting to cross the Cascade Mountains.
  • Individuals dependent on electricity for medical equipment or other essential needs.
