Snowpack conditions in Washington vary across different mountain ranges, providing crucial water resources for the state. The Cascades, Olympics, and eastern mountains contribute significantly to snow accumulation. The snowpack feeds into several runoff rivers and watersheds, including the Columbia, Yakima, and Skagit rivers, which play a vital role in irrigation, hydropower, and salmon habitats.
Winter climate characteristics in Washington involve a mix of maritime and continental influences. The mountains experience heavy precipitation, resulting in ample snow accumulation. The state's proximity to the Pacific Ocean and the presence of the Olympic and Cascade ranges create a rain shadow effect, leading to drier conditions east of these mountains.
Washington has a rich history in snow science and exploration. Mount Rainier, the state's highest peak, is the most extensively glaciated mountain in the contiguous United States. Notably, the Paradise Ranger Station on Mount Rainier holds the world record for the most annual snowfall at a single location, with over 93 feet recorded in the winter of 1971-1972.
