  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
  2. 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.

  1. 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.

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.

  1. 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.

At least 12 vehicles stranded in several inches of flood waters and mud resulting in water rescues. Numerous roadways were damaged across town. Dozens of buildings and residences have basements full of water. The historic El Rancho Hotel had 4 feet of water in their basement. Flood damage is an estimate.

    National Weather Service narrative

    The Balsam Wildfire was discovered during a very dry and critical fire weather event on the evening of April 27th, in Grants, NM. Fire crews were able to keep the fire to just 3 to 5 acres, but it unfortunately burned through a residential area. The Grants Fire Chief reported 7 structures were impacted with 2 firemen injured. Damage is an estimate.

  7. Jul 4, 2015Flash Flood$300,000
    National Weather Service narrative

    Heavy rain caused State Road 491 north of Gallup to close due to flooding and debris. County Emergency Manager reported flash flooding caused 4 inches of mud and 8 inches of water to enter a juvenile center on the east side of town. He also noted that a few bridges were temporarily closed due to flood waters, along with numerous county roads suffering damage. Exact location and extent of damage was unknown. Allen Joe Begay of White Cone, Arizona was swept away in flood waters while in the Rio Puerco.

  8. May 16, 2021Wildfire, Northwest Plateau$300,000
    National Weather Service narrative

    A grass fire started on Road 5211 near U.S. Highway 64 between Bloomfield and Lee Acres on the evening of May 16th. The fire spread quickly and engulfed a family home with a detached garage. The residence was completely destroyed, and the three family dogs that were inside at the time tragically died. There was also reported damage to an additional outbuilding. The fire prompted an evacuation of the area, but residents were permitted to return late on May 16th. By the morning of May 17th, the fire was 5 percent contained, but no longer posed a threat to any other structures. Damages are estimated for the loss of the residence as well as damages to the outbuilding.

  9. Jun 9, 2022Wildfire, West Central Highlands$250,000
    National Weather Service narrative

    The Cerro Bandera Fire began on June 9th on private land within the El Malpais National Monument. Dry and windy conditions allowed this fire to spread to 939 acres before it was contained on June 16th. Four structures, including one home, were destroyed. No other information was given. Damages are estimated.

  10. Aug 5, 2012Flash Flood$150,000
    National Weather Service narrative
