Oregon awakens to damp roads and low clouds, but eyes are already looking uphill. A significant winter storm is on its way, primarily impacting the Cascades.
A Winter Storm Warning is in force for the Oregon and Washington Cascades from early Tuesday until Thursday afternoon. Meteorologists warn that this will be a severe winter event that might disrupt mountain traffic for days.
Heavy snow begins at 4 a.m. Tuesday and intensifies throughout the day and evening. Snowfall rates can reach an inch per hour, particularly around Snoqualmie Pass, Stevens Pass, Santiam Pass, Willamette Pass, White Pass, and Mount Hood. Winds gusting from 35 to 40 mph will impair visibility and cause flying snow.
By Thursday, snow accumulations of 1 to 2 feet are forecast across much of the Oregon Cascades. Snowfall in Washington’s Cascades can range from two to four feet. The eastern slopes and Blue Mountains could receive 20 to 30 inches, with tree damage and scattered power outages probable.
Road conditions are anticipated to deteriorate quickly. Bridges and overpasses will freeze first. Travel may become extremely difficult or impossible, particularly during the peak snowfall on Tuesday and Wednesday. Backcountry travel is strictly discouraged.
Drivers who must navigate the highlands should reassess their preparations. Emergency experts recommend delaying travel wherever possible. If travel is inevitable, pack chains, food, water, warm clothing, and a flashlight. Keep the fuel tanks full.
This storm represents a significant shift farther into Winter 2026 in the Pacific Northwest. Conditions may temporarily improve late Thursday, but more systems are being examined behind the scenes.
