- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Jefferson 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.

- 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.

- The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

- Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
- 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.

- Feb 23, 2019Heavy Snow, Central Oregon$1.5 million
National Weather Service narrative
Persistent troughing off the coast of the Pacific Northwest focused a stream of mid-level moisture over the Inland Northwest resulting in a long duration snow event as the plume drifted north and south several times between the 22nd and 27th of February. Snowfall rates were greatly enhanced over central Oregon with the proximity of a nearly stationary surface boundary where snowfall rates were in excess of 1 inch per hour. Storm total snowfall amounts were measured at: 40 inches in Sisters, 33 inches in Bend, 30 inches in Redmond, 26 inches in Meacham, 22 inches in Prineville, 21 inches in Elgin, 16 inches in Mitchell, 14 inches in Lostine and La Grande, 12 inches in Pendleton and…

- May 3, 2010High Wind, Central Oregon$100,000
National Weather Service narrative
A tight pressure gradient combined with a cold frontal passage to produce widespread high winds and damage. Blowing dust in the Columbia Basin reduced visibility to near zero around Stanfield, Pendleton, and between Lexington and Hermiston. The blowing dust caused traffic accidents with an injury near Stanfield on Interstate 84. Peak wind gusts in mph included 13 miles west southwest of Mikkalo (58), 5 miles south southeast of Mikkalo (59), North Pole Ridge RAWS (65), Pendleton Airport (61), 10 miles north northeast of Pendleton (58), and Helix (60). Sustained winds of at least 40 mph were reported at 5 miles south southeast of Mikkalo. Downed trees were observed 1 mile south of…

National Weather Service narrative
A cold front brought damaging winds to central Oregon for several hours. Several large trees were toppled in Bend, leading to blocked streets and one isolated power outage. A construction fence also blew across a city road. In Prineville, part of a tin roof blew off an older house. A peak wind gust of 46 mph was measured at the airport in Redmond.
- Oct 18, 2007Strong Wind, Central Oregon$50,000
