Seattle Snow in December: A Winter Wonderland?
Seattle in December doesn’t always guarantee a blanket of snow, but it’s certainly possible. While December is one of the months where Seattle experiences snowfall, accumulations vary greatly year to year, making a white Christmas a delightful but unpredictable event. The chances of seeing snow in Seattle in December hover around a moderate level, and the city is generally prepared for winter weather challenges.
Historical Snowfall in Seattle During December
Seattle’s snowfall in December is somewhat variable. Some years bring significant accumulations, while others see only a dusting or none at all. According to Seattle’s climate data, average December snowfall is relatively low, but this average masks the significant fluctuations. Factors influencing December snowfall include the overall weather patterns, the arrival of cold air masses from the Fraser Valley in British Columbia, and the presence of moisture from the Pacific Ocean. Years with a strong La Niña pattern, for example, might see increased snowfall. Historical records can provide insights into past snow events, but predicting snowfall accurately remains a challenge.
Factors Influencing Seattle Snowfall
Seattle’s unique geography and climate contribute to the unpredictability of December snowfall. The city’s location near the Puget Sound and the Olympic Mountains can create microclimates, where some areas see snow while others remain rain-soaked. The elevation also plays a crucial role, with higher areas typically receiving more snow than lower-lying neighborhoods. As temperatures often hover around freezing point, even a slight change can determine whether precipitation falls as rain, snow, or a mix of both. The “Puget Sound Convergence Zone,” a weather phenomenon that can enhance precipitation, also impacts snowfall patterns.
Preparing for Potential Snow
While a major snowfall event isn’t guaranteed, it’s always wise to prepare for potential winter weather in Seattle during December. This includes having appropriate winter tires on your vehicle, stocking up on emergency supplies like food, water, and flashlights, and knowing how to safely heat your home during a power outage. The city of Seattle typically mobilizes snow removal crews to clear major roadways and transit routes. It’s also essential to check local weather forecasts and advisories to stay informed about any impending winter storms.
Navigating Seattle in Snow
If snow does fall in Seattle during December, navigating the city can be challenging. Public transportation may experience delays or route changes, and driving conditions can be hazardous, particularly on hills. It is a good idea to be aware of the area you will be traveling in and what routes will be cleared first by the city of Seattle. Walking can also be treacherous due to icy sidewalks. It’s advisable to wear appropriate footwear with good traction and to allow extra time for travel. Checking real-time traffic conditions and transit alerts can help you plan your route accordingly.
