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

National Weather Service narrative
The Forsyth Fire started on Thursday, June 19th, 2025. Initial reports from fire officials state the fire is suspected to have originated as a holdover from lightning in the Pine Valley Mountains. A long stretch of hot, dry, and windy conditions prevailed ahead of the fire's discovery on the 19th. A nearby RAWS station in Pine Valley (TT900) observed Red Flag conditions (wind gusts >25 mph and RH <15%) for about 16 hours from the afternoon of the 19th to the early morning hours on the 20th. A mandatory evacuation order for the Pine Valley community was issued at 9:21 PM on the 19th. Red Flag conditions redeveloped late morning on the 20th, with strong southwest winds eventually…

National Weather Service narrative
A landslide occurred 8 miles east of Cedar City, along Utah State Route 14. The landslide occurred sometime before 5 a.m. on the morning of October 8th, when the slide was discovered and the road was closed by the Utah Department of Transportation. The landslide was 1,700 feet in length, and destroyed an 800 foot section of State Route 14. The dirt on the road was as much as 100 feet deep in some places, and it was estimated that the slide consisted of 1.5 million cubic yards of dirt, rock, and debris. This led to the closing of a 12-mile stretch of State Route 14, which is a widely used road in southern Utah, particularly for tourists trying to get to Cedar Breaks National…

National Weather Service narrative
The Brianhead Fire started on June 17, when a man used a weed torch at his Brian Head area cabin, and the fire became out of control. The fire burned 71,672 acres, with most of the growth in the first two weeks of the fire. The Brianhead Fire destroyed 13 homes and 13 minor structures. A priority sage grouse habitat was also impacted east of the fire perimeter in the Panguitch watershed area. Costs associated with the fire were approximately $36.6 million, with rehabilitation efforts projected to cost double or triple that amount. At the height of the fire, approximately 1,831 personnel were fighting to contain the wildfire, and 1,562 people were evacuated from 11 communities in…

The Shingle Fire began on July 1st, five miles east of Duck Creek, Utah and 4 miles south of State Route 14. The fire was caused by sparks from an ATV. In total, the Shingle Fire burned 8,061 acres before it was 100% contained on July 11th. Four firefighters were injured while fighting the blaze. The fire caused the evacuation of approximately 500 structures, and ultimately destroyed one residence and one non-residential building. In addition to these property damages, fire suppression costs totaled $7.1 million.
- Jul 22, 2026Flash Flood$100,000
National Weather Service narrative
Flash flooding was reported into the town of Junction off the Cottonwood burn scar. Media reports that the flash flood broke through a berm built to divert flood waters, inundating portions of the town. Time estimated. Additionally, flash flooding from Cottonwood burn scar sent debris flowing over US-89 between mile markers 164 and 177.
- Jul 17, 2018Flash Flood$75,000
National Weather Service narrative
Heavy rain caused widespread flash flooding in the town of Marysvale. At least five homes were damaged, a gas line was broken, and mud covered many roadways in the area. The flood waters temporarily forced the closure of U.S. Highway 89 through the center of town.
- Feb 18, 2016High Wind, Southern Mountains$50,000

The automated sensor 2 miles south of Brian Head recorded strong winds for several hours, including a peak gust of 87 mph. Approximately 30 trees snapped and fell on runs at Brian Head Resort, and 20 trees fell on runs at Eagle Point. Both mountain resorts were closed at the time.
