Oregon Storm Alerts

Active National Weather Service hail, wind, thunderstorm, tornado, tropical and winter storm alerts covering Oregon, with the counties each one names and the office that issued it — plus what the state’s severe-weather season looks like and how each of these events actually damages a roof.

Below that, in its own lane, the smoke and fire family: fire weather, dense smoke, air quality, blowing dust and volcanic ashfall.

Radar over Oregon

Straight from radar.weather.gov and regenerated by NOAA roughly every two minutes.

National Weather Service radar for the Pacific Northwest, covering Washington, Oregon and Idaho. — Where precipitation is falling over Oregon right now. The National Weather Service publishes these mosaics by region rather than by state, so the frame runs past the state line and neighbouring states are visible in it. Radar shows precipitation, not damage — a return over a county is not evidence that any particular building was hit.

Smoke & fire lane

Smoke & fire alerts in Oregon

The National Weather Service issues a separate family of alerts for fire weather, dense smoke, air quality, blowing dust and volcanic ashfall. This lane reports that family for Oregon, kept apart from the storm alerts above because the two answer different questions.

Wildfire smoke is what drives smoke-damage losses, and it reaches a building through the same vents that keep an attic dry — which is why it belongs on a roofing page at all. Alerts describing particulate already in the air are listed ahead of fire-weather forecasts; that ordering is this lane’s own and is not a Weather Service ranking.

The 12 alert types this lane reports

Every one is a National Weather Service product and is listed under the name the Weather Service gives it. Grouping them into families is ours; the names are not.

Fire weather: Fire WarningExtreme Fire DangerRed Flag WarningFire Weather Watch
Dense smoke: Dense Smoke Advisory
Air quality: Air Quality Alert
Blowing dust: Blowing Dust WarningDust Storm WarningBlowing Dust AdvisoryDust Advisory
Volcanic ashfall: Ashfall WarningAshfall Advisory

The Weather Service defines each of these products and this site does not attempt to. What any one of them means, and the criteria an office issues it under, are at weather.gov.

This lane is informational and is not a safety resource. It reports which National Weather Service smoke and fire alerts are active and where, on a ten-minute refresh cycle, so it can lag the Weather Service.

During an active weather event, the authority is weather.gov and your local emergency management agency. Follow them, not this page.

Smoke exposure and air quality are health matters, and this page does not address them. It does not tell you whether it is safe to be outdoors or to work, what an air quality index number means for you or for anyone in your household, or what respiratory protection to use. Those questions belong with a clinician and with the agency that issued the alert. The federal air-quality authority is airnow.gov.

What smoke does to a roof assembly

An active alert is a record of conditions, not a finding about any building. These are the standing references on the building-assembly side of a smoke or fire loss.

Severe weather season in Oregon

Peak season

November–March

Oregon’s roof-damaging weather is a winter pattern driven by Pacific storm systems. The coast and the Columbia River corridor take the strongest sustained wind, and the long duration of these systems is what tends to find an aged flashing or an unsealed penetration. The Cascades and eastern Oregon add heavy snow loading. Hail and tornadoes are uncommon.

Seasons describe a pattern, not a schedule. The National Weather Service issues these products year-round, and the live list above is the only authority on what is actually running in Oregon right now.

What NOAA has recorded in Oregon

The archived record, not the live feed. Severe weather logged by the National Centers for Environmental Information over the covered years, split into the events NOAA keys to a county and the events it keys to a forecast zone.

Between 2016 and 2026, NOAA recorded 304 county-level severe-weather events across Oregon: 141 hail reports, 135 thunderstorm wind events and 28 tornadoes. Of the 141 hail reports carrying a measured size, 110 were 1.00 in across or larger.

A further 1,660 events over the same period were recorded against National Weather Service forecast zones rather than counties — 723 high wind events, 613 heavy snow events, 214 winter storms, 52 strong wind events and 49 ice storms. A forecast zone is not a county: it can span several or subdivide one, so these are reported here at state level and appear in no county total on this site.

Preliminary — not yet in the permanent archive

1 further preliminary storm reports have been filed against Oregon counties since June 1, 2026. They are counted separately from every archived figure above and are not added to any of them.

Preliminary reports covering 2026-05-31 onward come from National Weather Service storm reports filed as events occur. They have not yet been through the quality-control review that produces the permanent archive, and individual reports may later be revised, combined or withdrawn.

County figures and state figures. County figures count events NOAA recorded against a county (hail, thunderstorm wind and tornadoes). High wind, winter storms, ice storms, blizzards, heavy snow, hurricanes and tropical storms are recorded against National Weather Service forecast zones rather than counties, so they are reported at state level instead. Counts reflect events that were observed and reported.

Source. Archived figures come from the NOAA National Centers for Environmental Information Storm Events Database, covering 2016 through May 31, 2026. Reports after that date come from NOAA Storm Prediction Center preliminary storm reports. Both are US Government works in the public domain. This is a record of past weather; the live alert list at the top of this page is the only authority on what is running in Oregon now.

What these storms do to a roof

The damage mechanisms that matter in Oregon, in the order they generate work here.

Straight-line wind

Wind damage on a shingle roof usually starts as a broken seal rather than a missing shingle. Uplift pressure is highest at the edges — rakes, eaves, ridges and hips — and along any line where the roof plane changes, so that is where tabs lift and the factory sealant strip lets go first. Once the seal is broken, a shingle that still looks fine from the ground is no longer bonded to the course below it and every later wind event works on the same spot. Wind also drives debris, and impact damage from a branch or from another roof’s material is a separate mechanism from uplift.

Snow load and winter storms

Winter loads a roof rather than striking it. Accumulated snow is a sustained weight on the structure, and drifting means the load is rarely spread evenly — it piles against ridges, dormers, valleys and the low side of any change in roof height. Melt-and-refreeze adds the second mechanism: heat escaping through the roof melts snow that then refreezes at the cold eave, and the resulting ice can back water up under the covering, which sheds water flowing downhill but not water standing still.

Why the storm date matters

Property insurance works from a date of loss — a specific storm on a specific day over a specific area, not a general observation that a roof looks worn. That is why the county list and the effective and expiry times on each alert above are the useful part of this page: they are the National Weather Service’s own record that a given event covered a given county at a given time.

It also matters because hail damage is frequently latent. A fractured shingle mat can take a long time to become a leak, so the gap between the storm and the discovery can be considerable — and by then, establishing which storm did it is a records question rather than an observation. An alert naming a county is not evidence that any particular building was damaged; it is evidence of what the weather was doing over that county, which is where an assessment starts rather than where it ends.

This site does not edit, summarise or re-grade Weather Service text. Alerts are filtered into two separate lists — the event types that affect roofs, and the smoke, fire and airborne-particulate family — and each list is sorted. Nothing else is changed, and no alert is moved between the two lists to suit a heading.
