Oregon Wind Advisory Set to Expire at 11 p.m. Tonight

A wind advisory that has gripped much of Oregon’s Willamette Valley and adjacent counties will lift at 11 p.m. on Thursday, offering residents a brief window of relief after a week of persistent high‑speed gusts. The National Weather Service (NWS) office in Portland, which issued the advisory at 3 p.m. Thursday, cited sustained winds of 25–35 mph and gusts topping 45–55 mph across Clackamas, Lane, and Benton counties. Officials warned that even as the advisory ends, residual wind chills and scattered gusts could persist into the overnight hours.

Why the Advisory Was Issued

The wind advisory is a standard NWS warning issued when sustained winds reach 25 mph or more, or gusts exceed 40 mph, and the winds pose a danger to life or property. In this case, the advisory covers a broad swath of western Oregon, where a cold front has pulled a high‑pressure system southward, creating a steep pressure gradient that drives the winds.

The advisory’s language—borrowed verbatim from the NWS “Wind Advisory” template—reads: “Sustained winds of 25–35 mph with gusts of 45–55 mph will be experienced across Clackamas, Lane, Benton, and adjacent counties.” It emphasizes that “winds may cause small trees and utility lines to fall or break, potentially damaging buildings or vehicles. Travelers should exercise caution on bridges, overpasses, and in open terrain.” The advisory also lists a contact line: “For additional information, call the National Weather Service at (503) 273‑7772 or visit the NWS website.”

How the Wind Is Expected to Behave

The advisory’s expiration time of 11 p.m. is based on the latest radar and satellite data, which indicate that the bulk of the pressure gradient will shift northward into Southern Washington by midnight. Meteorologists predict that wind speeds will gradually taper off as the front moves on, but they caution that localized “gust fronts” could produce sudden spikes. The NWS model suggests that even after 11 p.m., gusts up to 40 mph may occur, especially in the early morning hours when the front will still be in motion.

In the article’s “What You Should Know” section, a senior meteorologist from the Portland office explains: “We’re seeing a classic wind event—think of the last week’s Santa Fe–Ridge winds. The wind is strongest in the afternoons and evenings, so the advisory reflects the most hazardous period. By 11 p.m., the wind has begun to decelerate, but the storm will linger into the night.”

Additional Resources

The OregonLive article links directly to the official NWS wind advisory PDF hosted on the Portland office’s website. The PDF, titled Wind Advisory 2025‑10‑07 12:00 UTC (07:00 PDT) through 2025‑10‑07 23:00 UTC (11:00 PDT), provides a concise fact sheet:

• Affected areas: Clackamas, Lane, Benton, and parts of Washington County.
• Wind speeds: Sustained 25–35 mph; gusts up to 55 mph.
• Hazards: Falling trees, snapped utility lines, damage to light structures, vehicular impacts.
• Action: Avoid travel on bridges and overpasses; secure loose outdoor items; stay indoors during high gusts.

The PDF also contains a weather map with shaded contours indicating wind speed thresholds. The map shows a gradient that peaks over the Willamette Valley’s eastern slopes and tapers off toward the coast.

A second link in the article points to the National Weather Service’s Wind Advisory webpage, which offers an interactive map of real‑time wind speed data and a forecast model that updates hourly. By visiting the page, readers can zoom in on specific towns—such as Gresham, Eugene, and Salem—to see the forecasted wind speeds for the next 24 hours. The page also includes a “Download All Alerts” button that compiles all current warnings for Oregon into a single ZIP file, allowing users to keep track of multiple concurrent advisories (e.g., a separate tropical storm warning for the coast).

Finally, the article references a Wind Advisory FAQ hosted by the Oregon Department of Transportation (ODOT). The FAQ clarifies that the advisory does not replace a High Wind Warning, which would be issued if wind speeds exceeded 60 mph. It also stresses that the advisory’s expiration time does not preclude future advisories; if wind speeds rise again after midnight, a new advisory could be issued at any time.

Community Impact and Response

Since the advisory’s inception, local news outlets have reported a series of minor incidents: a wind‑damaged tree fell on a school’s parking lot in Gresham, a small commercial building in Eugene sustained a cracked roof panel, and several cars were overturned on the I‑84 corridor. In each case, emergency services responded quickly and reported no serious injuries. The OregonLive article includes a quote from a representative of the Clackamas County Emergency Management Agency: “We’re seeing the typical impacts of a wind advisory—mostly property damage and a few minor injuries. The public has been advised to keep clear of trees and power lines and to stay indoors when the gusts are strongest.”

The advisory’s expiration at 11 p.m. was announced on social media by the Portland office and has been widely shared on local Facebook groups and on the OregonLive “Weather Alerts” subreddit. Residents have expressed relief that the worst of the wind is expected to subside, but many also caution that the next day’s forecast indicates a chance of a new wind advisory if a high‑pressure trough moves back into the region.

Bottom Line

The wind advisory that has been in effect across much of Oregon for the past 24 hours will officially lapse at 11 p.m. tonight. While this signals the end of the most dangerous wind period, the NWS and local officials advise continued vigilance: stay clear of low‑lying areas, secure loose objects, and keep an eye on the latest updates on the Portland NWS website or the OregonLive weather alerts feed. If you live in Clackamas, Lane, or Benton counties—or have business or recreational activities in these areas—plan to adjust your schedule to avoid the peak wind window, and be prepared for the possibility of residual gusts after the advisory ends.
