NWS issues special weather statement predicting snow late tonight and tomorrow morning

(Portland, Ore.) — The National Weather Service has issued a special weather statement saying that a strong winter storm front is expected to bring low snow levels late tonight and Tuesday morning in the lower elevations of the Portland metropolitan region. Snow levels could get close to 500 feet or lower Tuesday morning and possibly close to the valley floor in brief heavier showers. The Portland Bureau of Transportation advises travelers to be prepared for winter weather and slippery roads and sidewalks.

If snowfall impacts the Tuesday morning commute, people should avoid driving and take transit if at all possible or delay their trip until conditions improve. Motorists driving in the hills or other chain zones should be ready to use chains if conditions are snowy or icy. In conditions with frost, snow, ice and slush, motorists are advised to slow down, use headlights, allow extra stopping distance and share the road responsibly. Pedestrians and bicyclists should dress warmly and make sure they can be seen. Use lights, wear high visibility clothing, and be cautious crossing streets.

In addition, a wind advisory remains in effect until late this afternoon with a forecast for sustained winds at 31 to 39 miles per hour and gusts between 45 and 57 miles per hour. Winds of these magnitudes may cause downed trees, branches or power lines. Citizens are advised to report road hazards at 503-823-1700 and report a downed power line by calling PGE at 503-464-7777.

Transportation crews are monitoring conditions and will continue routine operations to keep streets safe and clean. The City’s snow and ice fleet is serviced and ready to go, chains are ready for use, plows and sanders are cleaned, sand piles are stocked and anti-icing chemicals are stocked. If snow and ice arrive, crews will patrol emergency response routes, major transit routes, bridges, overpasses and known trouble spots and treat as needed.

With rain in the forecast, crews cannot treat roads with anti-icing chemical because rain washes it away. Temperatures are predicted to stay above freezing levels tonight and tomorrow.

The City recommends Portlanders monitor conditions where they are traveling, watch the forecast and use The site provides links to street closures, highway road conditions, transit schedules and service alerts, and other emergency information.
