Portland, Oregon - Residents in the Cascades region of Northern Oregon and Southern Washington are preparing for the first significant snowstorm of the season, with freezing temperatures and up to a foot of snow expected. The National Weather Service (NWS) has issued a winter weather advisory, forecasting 2 to 6 inches of snow at elevations above 3,500 feet and 6 to 12 inches of snow in areas above 4,500 feet.

Starting from 5 p.m. Tuesday and lasting until 5 p.m. Wednesday, the region will experience a mix of rain and possibly light and brief snow accumulations, according to KOIN 6 Meteorologist Kelley Bayern. She suggests that the Oregon foothills could see snowfall down to about 2,500 feet.

In addition to the snowfall, the Lower Columbia Basin will face freezing temperatures as low as 28 degrees. A freeze watch has been issued by the NWS for Wednesday evening through Thursday morning. During this time, plants, animals, and unprotected plumbing will be at risk of freezing.

To counteract the effects of the freezing temperatures, the NWS advises residents to take precautions. Tender plants should be protected from the cold using coverings such as blankets or plastic, while outdoor water pipes should be wrapped, drained, or allowed to slowly drip to prevent freezing and possible bursting. Those with in-ground sprinkler systems are advised to drain them and cover above-ground pipes as well.

As the storm approaches, authorities are reminding residents to stay updated on weather advisories and to exercise caution while traveling, especially in areas of higher elevation. Road conditions are expected to deteriorate, and drivers are urged to drive slowly, maintain a safe distance, and use caution on bridges and overpasses, as they tend to freeze before other road surfaces.

The first significant snowstorm of the season is expected to bring a picturesque winter wonderland to the Cascades, but residents are reminded to prioritize their safety and take the necessary precautions against the freezing temperatures and potential hazards associated with the upcoming weather.
