PORTLAND, Ore. – NOAA’s Winter 2025–2026 outlook, released Thursday, Oct. 16, shows Oregon in line for a cold, stormy stretch that could last into early March — bringing deep mountain snow, frequent coastal rain, and periodic flooding threats. The Climate Prediction Center highlights above-normal precipitation and below-normal temperatures statewide, a hallmark of La Niña winters across the Pacific Northwest.
According to the National Weather Service in Portland, “This is shaping up to be a classic La Niña pattern for Oregon — very wet for the coast and valleys, and heavy snow in the Cascades.” Forecasters expect a steady stream of Pacific systems to hit the state through February, dropping feet of snow in the Cascades, the Blues, and the Wallowas. Lower elevations, including Portland, Salem, and Eugene, may occasionally see snow or icy rain during Arctic air intrusions.
ODOT warns of frequent winter travel disruptions along I-84 through the Columbia River Gorge and over mountain passes like Santiam and Government Camp, where chain requirements will be common. Coastal communities could see strong wind events and flooding, especially during king tides and heavy rains.
NOAA notes that colder-than-average air could persist into March, extending the snow season for Oregon’s mountains and ski areas. Residents are urged to clear storm drains, monitor flood watches, and stay prepared for power outages during high-wind storms.
For Oregon, Winter 2026 looks active, cold, and storm-driven — a classic Northwest winter that rewards early preparation from coast to crest.
