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

  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. Jul 26, 1998Flood, Morgan$1.1 million
    National Weather Service narrative

    A series of thunderstorm complexes over central and south central Missouri produced widespread flooding. Cooperative weather stations reported over 8 inches of rain at Versailles (Morgan County), Rolla (Phelps County, and Salem (Dent County). Flooding caused widespread damage to roads and low water crossings and bridges. The Missouri Governor declared a state of emergency for several counties in central Missouri including Benton, Dent, Maries, Miller, Morgan, Phelps, and Shannon. In Miller County, flooding caused widespread damage to roads and low water bridges. Significant damage occurred to corn (50% damaged), soybean (50% damaged), hay (35% damaged) crops. Cattle (300 head) and…

  2. Mar 12, 2006Tornado$850,000
    National Weather Service narrative

    A tornado initially touched down southwest of Gravois Mills and tracked through the city. 20 homes were destroyed while another 10 were damaged. This tornado was spawned from the same cyclic supercell that produced tornadoes back in Hickory, Polk, Dade, and Barton counties.

  3. Oct 1, 2022Drought, Morgan$580,000
    National Weather Service narrative

    Drought conditions improved across Morgan County by the end of October. The US Drought Monitor indicated that moderate (D1) drought conditions remained at the end of the month after several rainfall events helped ease drought conditions below severe (D2) drought levels. Impacts across the region were primarily felt in larger scale agriculture with farm and stock ponds low but improved. Dry conditions caused grasses to dry and significantly impact hay production causing losses in hay cutting. Many farmers saw impacts to row crops such as soy beans, corn and other specialty crops.

  4. Dec 27, 2015Flood$500,000
    National Weather Service narrative

    Several low water crossings were flooded and several rural roads had damage due to flood waters. This storm report will contain the damage estimates for the entire county for this event.

  5. Jul 17, 2023Hail$250,000
    National Weather Service narrative

    Hail up to tennis balls in size was reported in downtown Stover. Vehicles and roof damage occurred.

  6. Apr 27, 2026Hail$150,000
    National Weather Service narrative

    Hail up to 3 inches in diameter was reported in a mainly rural area. A home and several barns had roof damage and a few vehicles were damaged.

  7. May 19, 2025Thunderstorm Wind$130,000
    National Weather Service narrative

    Multiple trees and power lines were reported to be down. Additionally, a lightning strike caused a house fire, and a nearby machine shop suffered heavy damage.

  8. Apr 30, 2017Flood$100,000
    National Weather Service narrative

    Several roads sustained flood damage across the county. This report will contain the total dollar estimate for flood damage to infrastructure, businesses, and homes across Morgan County.

    An EF-0 tornado damaged some outbuildings and docks south of Rocky Mount in Morgan County. Maximum wind speed was estimated 75 to 85 mph.

  10. Jun 3, 2025Thunderstorm Wind$100,000
    National Weather Service narrative

    Thunderstorm wind gusts of at least 70 mph downed numerous trees in the Gravois Mills and Laurie areas. Some trees landed on homes.
