Weather conditions in Snoqualmie Pass, Washington, are set to shift dramatically over the coming days. A transition from two weeks of warm and wet weather to a cooler, wetter forecast will occur overnight.
Upcoming Blizzard Alert in Snoqualmie Pass
Heavy rainfall has impacted afternoon commutes, leading to low visibility and hazardous driving conditions. Wind gusts are expected to exceed 30 mph, especially across east-west bridges like the Narrows. Authorities have issued a high wind warning, anticipating gusts up to 50 mph by Wednesday morning.
The persistent rain and wind will likely cause tree damage and power outages, as waterlogged soil increases the risk of uprooted trees. Additionally, the risk of landslides remains elevated due to unstable hillsides from ongoing weather conditions.
Snow Levels Expected to Plunge
Currently, rain is falling significantly at elevations up to 6,000 feet. However, as a cold front arrives, snow levels are projected to drop to 2,500 feet overnight. This plunge in snow levels will contribute to heavy, blowing snow accumulating at mountain passes.
- Blizzard warning in effect through Wednesday
- Projected snowfall of up to 2 feet at volcanic peaks
- Nearly 1 foot of snow expected at Snoqualmie Pass
Travel in the high country will become dangerous due to blowing snow, prompting the necessity for caution among travelers.
Weather Outlook
By Wednesday afternoon, rain is forecasted to transition to showers and brief sunbreaks. High temperatures are expected to reach the mid-40s, a typical range for late December. As the day progresses, snow in the Cascades will become more showery, improving travel conditions at the mountain passes.
Wet weather patterns may persist through the weekend, although daytime temperatures in the lowlands are expected to stabilize in the 40s. This cooler weather will aid in regenerating the snowpack that has been lacking recently.
As winter officially begins on Sunday, residents hope for calm conditions leading up to the Christmas holiday.
