- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Curry County: 0.
- Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

Medium or heavy smoke. 5 so far in 2026.
- A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

- High tide flooding days are days on which a NOAA tide gauge recorded water at or above NOAA's minor flood threshold, set from the gauge's tide range, counted by meteorological year (May to April). These are the counts in NOAA's annual high tide flooding reports; they are not National Weather Service flood stages. Years with less than 80 percent of data are left out.

- Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

- Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

National Weather Service narrative
The first of a series of surges caused by the tsunami struck Port Orford at 07:11 PDT. The maximum recorded amplitude was 2.02 meters which occurred around the seventh surge. On the US West Coast, the only station that recorded a higher surge was Crescent City CA with a 2.47m amplitude. The surges gradually subsided during the next few days. Major damage occurred at the Brookings Harbor, where 40% of the floating docks were destroyed and many boats were damaged or destroyed. Docks, pilings, and channel buoys were also damaged at Gold Beach OR. Four men were pulled into the ocean at Pistol River. Two were rescued while the other two made it back to shore on their own.

The peak gust was 77 mph recorded at 25/0448 PST. The Port of Port Orford reported 100 mph winds and 28 foot waves, which damaged a jetty and caused extensive damage at the dock. Numerous crab totes were lost, the Hallmark Fisheries office was destroyed, other offices were flooded. and boulder were tossed into the dock and parking lot. Damage was estimated at $1 million dollars Trees toppled, some of which fell across trailers at the Madrona RV park. One trailer caught fire, and the occupant was injured.

National Weather Service narrative
The 42.3' steel-hulled crab fishing vessel Sarah Jo had a crew of 3. She was crossing the Coos bar around 4 pm local time, when the crankshaft broke, possibly as a result of rough conditions. After losing power, the boat then took a breaking wave on the bar, capsized, then sank. A USCG report shortly before the incident reported 10-12 foot steep breaking seas within the channel, and 8-10 foot steep seas just beyond the jetty. Conditions were worsening during rescue operations. Winds were south around 10 KT with 5 NM visibility. The bar was restricted to vessels below 40 feet. Note: The Sarah Jo was attempting to recover pots for the Eagle III, a crab fishing vessel that collided…

National Weather Service narrative
Unusually heavy surf battered the coast washing away part of Port Orfords sewage treatment system and threatened the town's water supply. Dune that seperates the ocean from Garrison Lake (Port Orford's water supply) was eroded allowing some salt water to spill into the the lake.
