Miller County

Every recorded tornado

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

Every storm within 100 miles

1. Tropical storms and hurricanes (34 kt or more, still tropical) at closest approach. Post-tropical remnants with gale-force winds are listed but not counted. Direct: track within 50 miles; near: within 100 miles. Distance is measured to the county boundary for counties and to the city centre for cities, using positions interpolated hourly between HURDAT2 fixes.

Smoke overhead

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.

River crests

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

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).

Mapped landslides

Mapped by MO DNR (1).

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 frozen precipitation began on the 30th, the precipitation type was freezing rain and sleet, with ice accumulations up to four inches in some areas. The second wave of precipitation occurred overnight causing large amount of snow to accumulate over the ice. Storm total accumulations ranging from 13 to 17 inches occurred from the Lake of the Ozarks Region, over to Vernon and Cedar counties. Meanwhile other areas north of the Interstate 44 corridor experienced storm totals ranging from seven to 12 inches.|The combination of the ice and snow…

2. Apr 16, 2026Hail$7.0 million
   National Weather Service narrative

   A slow moving elevated severe thunderstorm produced hail from the size of quarters up to tennis balls, 3 inches, in size as it moved across the city of Iberia. Significant damage to roofs, vehicles, and other structures occurred. This swath of hail was nearly 3 miles in length with hail falling for as much as 25 minutes across portions of the city.

3. May 22, 2019Tornado$4.0 million
   National Weather Service narrative

   A National Weather Service storm survey confirmed an EF-1 tornado with maximum winds of 104 mph began southwest of Eldon and tracked through Eldon before continuing northeast. The tornado eventually crossed into Cole County where it strengthened to EF-3 strength before impacting Jefferson City. In Miller County, the tornado touched down west of the Eldon Country Club and damaged numerous homes across the southern and eastern sections of Eldon. One injury occurred in this area. The tornado then tracked northeast, crossing Highway 54 twice, and uprooted or snapped numerous trees as it moved across rural areas in northeastern Miller County before crossing Highway AA at Spring Garden…

4. Jan 12, 2007Ice Storm, Miller$3.0 million
   National Weather Service narrative

   The southeast half of Miller County experienced ice accumulations up to one inch. This area experienced significant tree and power line damage. The northern half of the county experienced mainly a sleet pack which accumulated up to three inches. Little damage occurred in areas that experienced the sleet pack.

5. Apr 30, 2017Flash Flood$2.0 million
   National Weather Service narrative

   Several homes and business sustained flood damage across the county. Numerous roads and bridges were severely damaged or washed away across the county. This report will contain the total dollar estimate for flood damage to infrastructure, businesses, and homes across Miller County.

7. Nov 1, 2022Drought, Miller$900,000
   National Weather Service narrative

   Drought conditions improved across Morgan County by the end of November. The US Drought Monitor indicated that Abnormally Dry (D0) 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.

8. Apr 27, 2026Hail$750,000
   National Weather Service narrative

   Golf ball size hail was reported damaging at least 20 vehicles and breaking out windows. Roof damage to a home and business occurred.
