Oregon Storm Data: Hail & Wind History Since 2010
Deduplicated storm activity for Oregon, fused from NWS warnings, storm reports, official records, and FEMA declarations.
Latest Oregon hail and wind storms
- Last reported hail in Oregon (0.75 in.+, screening): August 15, 2026 — 1.00 in. reported at Unity (Baker County), NWS Local Storm Report.
- 2026 so far in Oregon: 4 hail days and 32 wind days statewide (days with a storm report or station gust at the screening thresholds; warnings alone never count).

Oregon storm facts
- StormAuditor's analysis of NOAA and National Weather Service records found 638 deduplicated storm events (wind, hail, tornado, and flood; NWS warning products included) in Oregon in the 12 months ending October 22, 2026.
- Storm activity touched 36 of 36 Oregon counties over that period.
- The most impacted county in Oregon was Malheur, with 50 events.
- The busiest day by event count in Oregon was December 17, 2025, with 103 events.
Oregon storm activity at a glance (last 12 months)
StormAuditor's consolidated public record currently shows 638 storm events impacting 36 of Oregon's 36 counties in the trailing 12 months: 444 wind events, 96 hail events, 2 tornado events, 96 flood events. Every count includes NWS warnings as well as observed reports, so tornado events mean tornado warnings and reports, not confirmed tornadoes.
Events are fused from National Weather Service warnings and Special Weather Statements, observed Local Storm Reports, official NCEI storm records, and FEMA disaster declarations, then consolidated into a single event table under the published methodology.
Wind covers thunderstorm and non-thunderstorm wind alike, so these counts measure something different from the NCEI entry counts in the history section below; the two are not comparable year to year. State totals also count NWS Special Weather Statements (radar-indicated hail or gusts below warning level); city pages leave those out.
Busiest days in Oregon by event count
Ranked by the number of 12-month events, NWS warnings included, so a day with many warnings can outrank a day with larger hail.
- December 17, 2025 — 103 events incl. warnings (flood, wind)
- October 25, 2025 — 51 events incl. warnings (hail, wind)
- May 28, 2026 — 43 events incl. warnings (hail, wind)
- December 18, 2025 — 32 events incl. warnings (flood, wind)
- December 9, 2025 — 25 events incl. warnings (flood)
Most impacted counties
Events of every type for each county — wind, hail, tornado and flood, NWS warnings and Special Weather Statements included. City pages count wind and hail events only, so a county number on a city page is never higher than the number here.
- Malheur — 50 events
- Harney — 48 events
- Umatilla — 44 events
- Clackamas — 40 events
- Tillamook — 37 events
- Clatsop — 27 events
- Baker — 23 events
- Lincoln — 22 events
Additional activity recorded under other NWS area names (forecast zones, tribal lands, and former census areas): Curry County Coast (8) · Foothills of the Northern Blue Mountains of Oregon (6) · Oregon Coast (6) · Clatsop County Coast (5).
How these numbers are counted
The storm numbers on this page are counted in four different ways, plus the free address check. Each answers a different question with its own size cutoffs, area and time span, so compare numbers within one group, not across groups.
- Storm days (latest hail and wind): A day in the last 12 months when at least one report anywhere in Oregon showed hail 0.75 in. or larger or wind of 45 mph or more (StormAuditor screening thresholds). Reports are NWS storm reports from spotters, the public and officials, plus weather-station gusts, which count from 50 mph. A warning on its own never makes a storm day. The "City pages hit" column and each city's last reported hail apply the same rule within 25 miles of the city. The statewide columns count reports inside Oregon only. City pages count reports within 25 miles of each city, which can reach into a neighboring state; those values name the other state, so a border city's value for a day can be higher than the Oregon value.
- Storm-date pages (NWS severe): A storm-date page is published only when at least one report or station gust within 25 miles of a city met the National Weather Service severe criteria (hail 1.00 in. or larger, or wind 58 mph or more), at least two separate observations were logged, and the day ranks among the most significant. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. Not every storm day gets a page; when one does, the page and the storm-day table show the same largest hail and strongest gust.
- Events (12-month counts): Events count the Oregon storm log: NWS warnings and Special Weather Statements (a lower-level NWS alert), storm reports (wind 50 mph+, hail 0.75 in.+), station gusts, NCEI entries and FEMA disaster declarations, for each county affected, floods included. One event is one place on one day, counted separately for each type (wind, hail, tornado, flood). A weather station or storm-report point counts once a day, at that day's highest reading, however many readings it filed; a place with hail and wind on the same day is two events. NWS warnings and Special Weather Statements count once per county per day, and NCEI entries and FEMA declarations once per place per day. A storm report that relays an airport weather station's reading (the same station, the same gust and the same time) counts once, as the station reading. The same report arriving through another feed (SPC or NCEI) is one record. The most impacted counties list uses this count. City pages count only wind and hail within 25 miles and leave out floods and Special Weather Statements, so city counts do not add up to the state total, and a city page's county count is a wind-and-hail count that is never higher than the same county's number here.
- NOAA history (since 2010): The official NOAA storm record (NCEI Storm Events) in Oregon from January 1, 2010 to the day before the 12-month window starts: hail 0.50 in.+, thunderstorm wind 40 mph+ and tornadoes. It is a separate, older record with its own "storm days" (days with any entry), so its counts are not compared with the 12-month numbers.
- Free Report Snapshot: A free YES/NO estimate for one address, from radar and wind analysis at the property rather than area reports, at the same screening thresholds: hail 0.75 in. or wind 45 mph.

Oregon hail and wind history in NOAA NCEI records, 2010–Oct. 2025
This section covers January 1, 2010 through October 21, 2025. Storms from October 22, 2025 on are in the 12-month summary above, so no date is counted in both.
NOAA's Storm Events Database holds 676 NCEI Storm Events entries in Oregon for this period, on 213 separate storm days. Hail outnumbers thunderstorm wind here: 377 hail reports against 256 wind reports.
Hail peaks in August (27% of all hail reports); thunderstorm wind peaks in May. December through February accounts for 10 storm days.
Storm days ranged from 9 in 2017 to 22 in 2010. Across 2022–2024, Oregon averaged 12 storm days a year, below the 15-year average of 13. The latest five full years (2020–2024) averaged 12 storm days, down from 17 in 2010–2014.
The largest hail in these records for Oregon was 2.50 in. (tennis-ball size), reported on August 11, 2022 in Wallowa County. Hail of 2 inches or more appears in 6 different years of this record, the latest being 2022. Measured thunderstorm gusts topped out at 91 mph (Sherman County, August 17, 2024). NCEI also lists 43 tornado entries in Oregon — one entry per county a tornado crossed.
- Average: 13 storm days a year (2010–2024)
- July and August: 51% of all hail reports
- Most hail reports in one year: 51 in 2010
- Hail of 1 in. or larger reported in every full year, 2010–2024
