Seattle, WA – Three words in a winter weather warning could signal an exceptionally dangerous storm across Washington during the 2026 27 winter season. From Seattle and Tacoma to Spokane, the Cascade Mountains and eastern Washington, residents should understand the rare wording before severe conditions develop.
According to NOAA's Weather Prediction Center, the National Weather Service is expanding the use of "Particularly Dangerous Situation," or PDS, wording in select Blizzard Warnings and Ice Storm Warnings.
The language is intended for rare storms posing extraordinary threats to lives, transportation and critical infrastructure.
What Are the Three Words Washington Residents Should Know?
"Particularly Dangerous Situation" highlights exceptional danger within an existing winter weather warning.
In a Blizzard Warning, PDS wording could emphasize life threatening conditions involving powerful winds and severely reduced visibility from falling or blowing snow.
In an Ice Storm Warning, it could highlight potentially devastating ice accumulation.
Why Could This Matter Across Washington?
Washington's winter hazards vary significantly by region.
Seattle, Tacoma and Everett can experience disruptive snow and freezing rain, while communities near the Columbia River Gorge face particular risks from ice accumulation.
Spokane, Pullman and eastern Washington can experience heavy snow, strong winds and dangerous blowing snow.
Mountain routes near Snoqualmie Pass, Stevens Pass and White Pass also face intense snowfall and major travel disruptions.
During an extreme event, Interstate 90 between Seattle and Spokane, Interstate 5 through western Washington, and Interstate 82 across central Washington could become hazardous or impassable.
Heavy ice can damage trees and power lines, potentially leaving homes without electricity or reliable heating.
These are possible impacts, not predictions of an approaching storm.
Is PDS a New Winter Weather Warning?
No. PDS is additional wording within certain existing Blizzard Warnings and Ice Storm Warnings, not a separate warning category.
Most Washington winter storms will not receive the designation.
What Should Washington Residents Do?
If PDS wording appears in a local warning, residents should avoid unnecessary travel, follow emergency instructions and prepare for prolonged disruptions.
Drivers should check Washington State Department of Transportation road and mountain pass conditions before traveling.
The expanded terminology does not mean a catastrophic winter storm is currently forecast for Washington.
