National Weather Service Issues Winter Weather Advisory for Union, Wallowa Counties

La Grande, Union, Joseph and other Blue Mountain communities were put on notice after the National Weather Service Pendleton office issued an "URGENT – WINTER WEATHER MESSAGE" at 11:45 a.m. PST Tuesday, Feb. 17, 2026, warning of "Snow. Additional snow accumulations of 3 to 6 inches." The product stated the winter weather advisory was in effect until 3 p.m. PST Wednesday and cautioned that travel could be difficult during periods of moderate to heavy snow.

The official product header for newsroom verification included ORZ049-050-503-180800- and the product code /O.EXB.KPDT.WW.Y.0003.000000T0000Z-260218T2300Z/, and it explicitly listed the impacted area as "Grande Ronde Valley-Wallowa County-Southern Blue Mountains of Oregon- Including the cities of Joseph, Cove, Ukiah, Wallowa, Union, Elgin, Enterprise, North Powder, La Grande, and Long Creek." The Pendleton office timestamp appears in the notice twice as "1145 AM PST Tue Feb 17 2026."

Local outlet Elkhornmediagroup republished the Pendleton message in a piece by Garrett Christensen on Tuesday, February 17th, 2026, noting that "Residents and drivers in Union and Wallowa counties, as well as other surrounding areas, should be mindful of a winter weather advisory issue by the National Weather Service for the Blue Mountain Region." The advisory's impact language was explicit: "Travel could be difficult due to periods of moderate to heavy snow." Drivers are urged to slow down and use caution while traveling and to check road conditions by calling 511.

Public-health and equity concerns were underscored by separate action in western Washington. Thurston County Public Health and Social Services declared a "Hazardous Weather Event Declared for the Nights of Wednesday, February 18 & Thursday, February 19, 2026" after the National Weather Service forecast below-freezing nights with "Extended extreme cold temperatures expected. Sleet & snow possible." Thurston County warned that "Extreme cold temperatures are dangerous for those without shelter" and said it would increase shelter-in-place efforts and extend overnight shelter capacity for those nights. Thurston named shelter options and contacts explicitly: Union Gospel Mission for single adults, St. Michael’s Parish and Sacred Heart for single men, and a county shelter hotline at 1-844-628-7343; Public Information Supervisor Renae Miller can be reached at (360) 463-0362 or renae.miller@co.thurston.wa.us.

Other National Weather Service offices were issuing their own regional advisories; for example, a Bellemont office notice for Arizona's Mogollon Rim, Kaibab Plateau and White Mountains projected "between 3 and 6 inches" in that region with advisory hours from 8 p.m. Monday to 5 p.m. Tuesday. These are separate warnings for distinct geographies and do not alter the Pendleton advisory for the Blue Mountains.

Union and Wallowa County residents should plan for disrupted travel in and between named towns such as La Grande, Enterprise and Long Creek while the Pendleton advisory was active, and follow local road-condition reporting via 511 to reduce risks during periods of moderate to heavy snow.
