Seattle, Washington – As the holiday season approaches, travel preparations are gearing up across Washington State, particularly as one of the peak travel periods, from December 19 to December 23, nears. The region faces potential weather disruptions due to an active Pacific pattern that promises widespread precipitation, bringing rain to lower elevations and a mix of snow or freezing rain in mountainous areas.
While Sunday remains relatively calm, weather conditions are expected to worsen by mid-week. The National Weather Service in Seattle forecasts rains starting late Thursday into Friday throughout western Washington, with possibilities of heavy rainfall at times. There is a concern for fluctuating snow levels that could potentially shift rain to snow or freezing rain at higher elevations and mountain passes, particularly overnight.
Travelers in the Seattle metro area should be prepared for steady rain, which may slow down traffic along major highways such as I-5, I-90, SR-520, and I-405 during peak holiday travel times. Increased congestion, reduced visibility, and standing water can contribute to delays, especially if heavy rain coincides with commute hours. Ferry services may also experience delays due to adverse weather conditions and high passenger traffic.
Mountain travel could be particularly hazardous. Areas like Snoqualmie Pass, Stevens Pass, and White Pass may encounter snow-covered roads or icy surfaces depending on timing and snow accumulation. The Washington State Department of Transportation advises travelers to expect possible chain requirements and to monitor pass conditions closely, urging people to avoid non-essential mountain travel during significant precipitation.
Air travel at Seattle-Tacoma International Airport could face delays due to ongoing rain, low clouds, or windy conditions coinciding with busy holiday traffic. Airport officials recommend that travelers arrive early, stay updated on flight statuses, and allow flexibility in their travel plans.
Given the forecast of above-normal precipitation across the Pacific Northwest, this holiday travel season is likely to be both wet and time-sensitive. Travelers are reminded to charge their devices, pack emergency supplies, and allocate extra travel time as the holiday rush intensifies across Washington. The goal is to ensure safety and maintain smooth travel during what is traditionally a busy and bustling time of year.
