Oregon greets the day calm and quiet, but conditions are set to change fast across the Columbia Basin. By tonight, winds howl across open land near Pendleton, rattling windows and bending trees as a powerful system moves in.
According to the National Weather Service in Pendleton, a High Wind Warning is in effect from 10 p.m. tonight through 4 p.m. Wednesday. Southwest winds of 25 to 35 mph are expected, with gusts reaching up to 65 mph, especially in foothills and exposed areas.
The strongest winds are likely late tonight into Wednesday morning. Travel could become hazardous, particularly for high-profile vehicles. Drivers on I-84 and nearby highways should prepare for sudden crosswinds and blowing debris. Power outages are possible as tree limbs and power lines are stressed.
Rain arrives alongside the wind, adding slick pavement and reduced visibility. While snowfall is not expected in Pendleton, nearby higher elevations could see early winter weather impacts as colder air wraps into the system. Residents should secure loose outdoor items before winds increase.
Temperatures remain mild for December, with highs near the upper 40s Wednesday. That warmth limits freezing concerns locally, but gusty winds can still cause structural damage and extended outages. Officials urge residents to remain indoors during peak wind periods if possible.
By Thursday, winds ease but rain lingers across the region. Roads may remain wet, and fallen debris could slow commutes. Crews may still be responding to downed trees and power issues into the afternoon.
Looking ahead to the extended five-day outlook, rain chances continue through Friday with cooler nights dipping into the 30s. Late-week models hint at a rain-snow mix in surrounding higher terrain by the weekend, signaling a gradual winter shift as Christmas travel approaches.
Secure property now, plan alternate routes, and avoid unnecessary travel during peak winds.
