  1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Presidio County: 0.
  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.

Months each year with a Palmer index of −3 or lower, 1895 to 2025. Twelve means the whole year.
  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.

    National Weather Service narrative

    A wet microburst centered over eastern Presidio caused extensive damage over portions of the city. The winds destroyed 7 mobile homes and damged up to 50 homes, businesses, and a school. Wind estimates put the speeds at up to 100 mph in the worst damage. Eight families were left homeless after the storm. Power was out for about 5 1/2 hours in parts of the city. About 3/4 inch of rain fell in 15 minutes during the storm. A survey of the damage path revealed a strongly divergent pattern with damage on the east side of the center pushed to the southeast and damage on the west side pushed to the northwest or west.

  2. Sep 9, 2008Flash Flood$1.0 million
    National Weather Service narrative

    On September 9, the levees near Redford, TX failed. This resulted in water covering the entire city of Redford. A high water rescue was reported near Alamito Creek.||Heavy rain made matters worse by September 14. Flash flooding was occurring in the city of Presidio and border patrol closed the International Bridge on September 16. The Mexican side of the bridge was covered in water and levels continue to rise. Water also topped the levees near Presidio Golf Course on the 16th and 17th. Border patrol reported that nearly 15 feet of water was located in the fields near the golf course, with 3 to 4 feet of water covering the golf course itself.||The International Boundary and Water…

  3. Jul 2, 2002Thunderstorm Wind$200,000
    National Weather Service narrative

    A severe thunderstorm produced damaging outflow winds in Presidio. A warehouse was destroyed and four homes lost roofs. Small hail collected up to 6 inches deep in some locations around town. Slightly larger hail occurred approximately 30 minutes later, around 615 PM CDT, as the main core of the severe thunderstorm moved over the community.

  4. Jun 3, 2005Hail$100,000
    National Weather Service narrative

    Hen egg size hail mixed with smaller hailstones to produce damage to roofs and vehicles in Marfa. This hail occurred during the second of two severe storms to impact the Marfa vicinity during the late evening and early morning hours of the 2nd and 3rd.

  5. Jun 20, 2002Flash Flood$100,000
    National Weather Service narrative

    The Texas Department of Transportation reported flash flooding resulting in high water in homes and businesses...as well as street flooding in the city of Presidio.

  6. Jun 3, 2005Hail$50,000
    National Weather Service narrative

    Large hail fell over Marfa again as a second severe storm affected the area shortly after midnight CST. Reports indicated that hail up to the size of half-dollars persisted for nearly twenty-five minutes. The long duration of one and a half inch diameter hail and occasionally larger stones, resulted in damage to numerous roofs and vehicles.

  7. Jun 2, 2005Hail$25,000
    National Weather Service narrative

    The first of two hail storms to affect the Marfa area struck at 23:00 CST. Large hail ranging in size from ping pong balls to golfballs fell along U.S. Highway 67 near the city. This initial storm is believed to be responsible for minor roof damage, however, a more significant hail storm impacted Marfa just an hour later and likely produced a majority of the damage.
