Winter Weather Advisory: Snowstorm Expected in Oregon Mountains

Winter Weather Advisory Issued for Oregon Mountain Passes

The National Weather Service in Portland has issued a Winter Weather Advisory for Oregon’s mountain passes, effective from March 31st to April 1st. Travelers should prepare for potentially hazardous conditions as a significant snowstorm is forecast to impact higher elevations.

What to Expect: Snowfall and Wind

A total of 10 to 18 inches of snow is predicted, accompanied by winds gusting up to 35 mph. These conditions will likely make travel on mountain highways treacherous, especially during the night of April 1st. The snowfall is expected to reach as low as 2,500 feet, but the heaviest accumulation will occur above 4,000 feet.

Affected Mountain Roadways

The following roadways are most likely to be impacted by the winter weather:

Highway 22 at Santiam Pass
Highway 58 at Willamette Pass
Highway 26 in the Mount Hood area near Government Camp

Motorists are urged to exercise extreme caution, allow extra travel time, and be prepared for potential road closures. Check current road conditions before you go using TripCheck.com.

Impact on Ski Areas & Snowpack

While the fresh snowfall will provide a temporary boost to Oregon’s higher-elevation ski areas, improving conditions for skiers and snowboarders, it won’t significantly address the state’s concerning snowpack levels. Currently, Oregon’s snowpack is at a record low, measuring just 14% of normal statewide, and as low as 9% in the Central Cascade Range. This is the lowest snowpack recorded since 2015 and ranks among the worst in data dating back to 1981.

This year’s winter – encompassing December, January, and February – tied for the warmest on record, contributing to the diminished snowpack. The lack of snow has significant implications for water resources throughout the state. You can find more information about Oregon’s snowpack from the Oregon Water Resources Department.
