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

Days each year on which a satellite-traced plume of medium or heavy smoke covered the county’s population centre, 2011 to 2025.
  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.

  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).

Mapped by CO GS (3).

  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.

The tornado then moved southeast and intensified with EF1 and EF2 damage observed 9 miles south of Elizabeth, with substantial damage to a farm, trees, and snapped power poles. The tornado moved on a more southerly track for the next 2 miles with additional EF1 and EF2 damage 11 miles south of Elizabeth. The tornado leveled a 70-yr old barn and a nearby cinder-block shed was torn open. Major tree damage was also observed. The tornado then continued southward for another mile before lifting with some EF0 and EF1 damage 12 miles south of Elizabeth. Minor damage to another home was observed…

    Heavy rain caused flash flooding along Interstate 70 at the River Bend Exit. Several cars were reportedly stuck in the floodwaters.

  9. May 8, 2015Flash Flood$25,000
    National Weather Service narrative

    Flooding and flash flooding washed out several county roads including: CR73 from CR112 to CR98; Freese Road from Colorado 86 to CR112; CR102, from Double Tree Ranch to the top of the Bluff; CR9 between Colorado 86 and CR98; CR106, from Canyon Road to CR13; Maul Road also suffered extensive damage.

  10. Jul 4, 2010Flash Flood$25,000
    National Weather Service narrative

    Intense thunderstorms, producing heavy rainfall in excess of 5 inches in one hour, produced flash flooding in the vicinity of Elizabeth. Numerous county roads were washed out. The combination of heavy rain and hail made it necessary to run snow plows through the town. Extensive basement flooding was also observed.

  1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
