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

  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.

  1. 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).
  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).

  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.

  1. Jan 26, 2009Ice Storm, Adair$3.3 million
    National Weather Service narrative

    Upper level disturbances passing through the Southern Plains resulted in precipitation development north of a stationary arctic front located in North Texas. Freezing rain began across the area during the late morning hours of the 26th and became more widespread and heavy during the afternoon and evening hours. Freezing rain changed to sleet north of a Okemah-Wagoner-Colcord line during the morning of the 27th with heavy freezing rain continuing south of that line. The heaviest icing and most widespread power outages and tree damage occurred across portions of Cherokee, Sequoyah, Muskogee, and Adair Counties where one to one and a half inches of ice accumulated. More than 100,000…

  2. Nov 28, 2001Ice Storm, Adair$1.0 million

    Freezing Rain accural totaled 1/2 to 1 inch that downed trees and utility lines across parts of the county. Power outages were common across this area.

  3. Jun 21, 2000Flash Flood$500,000
    National Weather Service narrative

    Heavy thunderstorm rains caused flooding of numerous rural roads. One of the major roads which were flooded was Highway 62 between Westville and Proctor. The flooding did substantial damage to gravel roads and bridges. The rising water in streams also flooded a few homes in Proctor and Chewey. Three homes were also flooded near where Shell Branch Creek flows into Baron Fork Creek.

    National Weather Service narrative

    This tornado developed south of the E 820 Road and west of the S 4700 Road, where large tree limbs were snapped and homes were damaged. It moved east-northeast across the cemetery snapping softwood trees.
