PORTLAND, Ore. — The National Weather Service (NWS) in Portland has issued an updated winter weather advisory for the South Washington Cascades, warning of fresh snowfall, gusty winds, and hazardous road conditions through Saturday morning at 10 a.m.
Snow and Wind Expected Through Saturday
According to the NWS update issued at 2:21 p.m. Friday, the region can expect additional snow accumulations between 1 and 3 inches at pass level and up to 4 to 8 inches above 5,000–5,500 feet.
Wind gusts could reach 35 mph, creating low visibility and drifting snow, particularly on higher mountain passes.
“Roads, and especially bridges and overpasses, will likely become slick and hazardous,” the NWS said. “Have a winter emergency driving kit readily available, including flashlights, blankets, non-perishable food, and tire chains.”
The advisory remains in effect until Saturday, December 20, at 10 a.m.
Travel Conditions and Safety Precautions
Motorists are urged to use extreme caution when traveling through mountain passes and to be prepared for rapidly changing weather conditions. Snow and freezing rain could make roads treacherous, while strong winds may lead to blowing snow and reduced visibility.
The NWS also warned that walking surfaces could be slick, advising pedestrians to “walk with extra care” on icy sidewalks and driveways.
Winter Driving Tips from the National Weather Service
With thousands of weather-related crashes reported annually in the U.S., the NWS recommends the following precautions when driving in snowy or icy conditions:
- Slow down and plan ahead: Allow extra travel time and drive cautiously, especially near bridges and elevated roadways where ice forms first.
- Stay informed: Check road conditions and local forecasts before traveling.
- Be prepared: Keep an emergency kit in your car with essentials like a shovel, flashlight, water, warm clothing, and snacks.
- Avoid unnecessary travel: If conditions deteriorate, it’s safest to delay your trip.
- Don’t crowd snowplows: Give plows and sand trucks plenty of space to operate safely.
- If stranded: Stay in your vehicle, keep warm, and use hazard lights to remain visible until help arrives.
Outlook
Snow is expected to taper off by mid-morning Saturday, but cold air will linger into the weekend, keeping road conditions icy in shaded and elevated areas.
