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

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.

- 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).

- Jun 13, 2012Hail$122,000
National Weather Service narrative
A thunderstorm moved over Brewster County and produced golfball hail in Marathon. Windows were broken and vehicles were dented from the hail. The cost of damage is a very rough estimate.
- May 26, 1998Hail$100,000
National Weather Service narrative
This small, but intense storm formed on an outflow boundary from storms to the north in Pecos County. The storm built right over the town of Marathon then slow moved to the southeast and weakened.
- May 10, 2009Thunderstorm Wind$88,000
National Weather Service narrative
A NWS Storm Survey concluded that damage was done to 44 power poles near Ranch Road 2627 in Brewster County, TX. Some of the poles were snapped 3 to 4 feet above the ground and all the poles fell to the south as the storm moved in the same direction around 20 mph. The poles were not consecutively snapped in a row. At times, there were 15 snapped...then a gap...and then more snapped as you moved southeastward down the line. Please see the attached images for a detailed look at the damage path.
- Jun 15, 1997Thunderstorm Wind$70,000
National Weather Service narrative
Wind damage occurred to several buildings on a ranch located on Taurus Mesa. Much of the damage was limited to corrugated metal that was strewn across the countryside. Rear-flank downdraft (RFD) winds were thought to have been the mechanism for the high winds. The RFD then hit State Highway 118 where the Longhorn Ranch Motel sustained wind damage. A 12x20 foot sign was blown down as well as damage to doors and the roof.The Red Cross determined that 2 houses were destroyed and 6 houses sustained major damage in the area near the motel.

- Jul 3, 2025Flash Flood$50,000
National Weather Service narrative
Emergency Management in Alpine reported one home inundated by flooding due to heavy rainfall and numerous road closures by local authorities. The time of occurrence is estimated by radar. The total cost of damages is also estimated.
