  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.

  1. 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.

  2. 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).

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

    Hail from quarter to golf ball size, with occasional hail stones the size of tennis balls accumulated to about 3 inches in the Tularosa area. The hail was driven by wind gusts up to 80 mph, and broke windows, damaged roofs and sidings to more than 500 homes in Tularosa.

  2. Jun 22, 2006Flash Flood$1.3 million
    National Weather Service narrative

    Strong thunderstorms developed over the southern Sacramento Mountains and along the eastern heights of Alamogordo. One storm in particular dropped about an inch and a half of rain in 40 minutes over Marble Canyon , which drains into eastern Alamogordo. Other storms added heavy rain and several inches of drifting small hail to that section of town. Strong winds blew shingles off houses, but flooding was the main problem. Roads along the eastern heights turned into raging torrents which flowed westward into the center of town. Mud flowed into numerous houses and several vehicles were swept into arroyos. A gas main was broken which led to the evacuation of residents in the vicinity.…

  3. Aug 16, 2006Flash Flood$600,000
    National Weather Service narrative

    Heavy rainfall along the western slopes of the southern Sacramento Mountains led to excessive runoff and major flooding in Alamogordo and Boles Acres. Numerous roads throughout the area were closed, covered with water and debris. There were also some rescues of people trapped in their homes.

  4. Mar 13, 2019High Wind, Sacramento Mountains Above 7500 Feet$500,000
    National Weather Service narrative

    NWS Storm survey revealed hundreds of ponderosa pines were either uprooted or snapped in the Village of Cloudcroft which resulted in damage to 30 structures, 10 vehicles and blocking 15 roads. Prior to the damage occurring, light to moderate frozen precipitation fell which led to rime ice buildup on the windward side of exposed trees. Across the entire area, over 1000 trees were snapped or uprooted due to sustained winds of 60 to 70 mph through much of the day with gusts over 100 mph. Cloudcroft lost power for over 24 hours starting around 11 am on 3/13. ||The most significant damage was located along a north to south exposed ridge line on the windward side of the mountain. Most…

  5. Aug 1, 2006Flash Flood$400,000
    National Weather Service narrative

    Several thunderstorms with heavy rains moved southward across the southern Sacramento Mountains, dropping 2 to 3 inches of rain. Flash flooding occurred from Cloudcroft to Timberon, with many roads washed out and structures damaged in the Timberon area.

  6. May 28, 2008Thunderstorm Wind$360,000
    National Weather Service narrative

    A wet microburst estimated at 80 mph destroyed a double wide mobile home, flipped several others, unroofed a few homes, and blew down several trees, power poles and power lines.

  7. Aug 13, 2006Flash Flood$300,000
    National Weather Service narrative

    A stationary thunderstorm dropped several inches of rain on Mayhill, with some residents and area ranchers reporting up to 5 inches in an hour. This resulted in a wall of water 9 to 10 feet high down the Rio Penasco River. Extensive flash flooding closed Highway 82, and damaged roads, bridges and homes.

  8. Jun 4, 2019Tornado$250,000
    National Weather Service narrative

    Storm survey showed a mobile home was completely destroyed with 3 other residences receiving moderate damage due mainly to flying debris. Several out buildings including sheds and barns were either completely destroyed or heavily damaged. One out building was shifted off it's foundation and moved approximately 9 feet north. A metal silo used for storage was lifted off it's foundation and traveled airborne for approximately 400 feet before striking one of the residential structures.

  9. Jun 23, 2009Flash Flood$200,000
    National Weather Service narrative

    Slow moving thunderstorms dropped nearly 3 inches of rain in the Cloudcroft area, which led to flash flooding in and near the town. Water was over two feet deep in parts of Cloudcroft, resulting in some apartments flooded. Rock slides also occurred along Highway 82 in the area.

  10. Jul 17, 2008Flash Flood$200,000
    National Weather Service narrative

    Rainfall amounts of up to 2 inches fell on the South Tularosa Fire burn scar above Mescalero, resulting in excessive runoff. Logs washed on to Route 10, and much debris blocked residences. A fish hatchery was destroyed which killed all the fish.
