Johnson County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Johnson County: 2.
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.

Storm Prediction Center severe weather database, 1950 to 2025.

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.

National Hurricane Center HURDAT2, 1851 to 2025.

Every large fire

1. Large fires mapped by the Monitoring Trends in Burn Severity program since 1984: 1,000 acres or more in the West, 500 or more in the East. Prescribed burns are excluded. Acres here are the part of each perimeter inside this place.

Monitoring Trends in Burn Severity (USGS and U.S. Forest Service), 1984 to 2026.

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.

NOAA NCEI nClimDiv county Palmer Drought Severity Index, 1895 to September 2026, issued October 6, 2026.

Every earthquake of magnitude 4 or more within 50 miles

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 KY GS (1,377), NASA (2).

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.

   National Weather Service narrative

   A damage survey team from the National Weather Service Forecast Office in Jackson, Kentucky determined that an EF-3 tornado tracked across central Johnson County on March 2, 2012. The tornado had a path width of about 3/4 of a mile and estimated maximum wind speeds of 160 mph. The tornado crossed into Johnson County just west of the Asa community at 708 pm EST and continued east-northeast exiting the county between the Boons Camp and Davisport communities around 725 pm EST. The towns of Hagerhill and West Van Leer were particularly hard hit with several structures totally destroyed. Two fatalities occurred in Johnson county as a result of this tornado. ||Ten to twenty houses and a…

   National Weather Service narrative

   On the afternoon of May 30th, a warm front was draped across eastern Kentucky. With extremely moist and unstable air, this boundary helped spark the beginning of a most unusual event for eastern Kentucky, and for that matter, for the country. Countless supercell thunderstorms developed along this boundary for hours on end, causing widespread tree damage and damage to structures. Flash flooding was also occurring with these storms which contained torrential rain. Unfortunately for eastern Kentucky, this was not the end to the severe weather or the flooding. Later in the night, mostly in the early hours of May 31st, a potent cold front burst through, bringing destruction to most if…

   National Weather Service narrative

   Flash flooding occurred in the Redbush and Flatgap communities, with devastating flooding occurring along Big Mudlick Creek and Ramey Branch. Four fatalities occurred and over 50 swift water rescues were performed in this area. Entire double wide houses were seen floating down Big Mudlick Creek and getting forced under a bridge. More than 150 homes were destroyed with as many as 500 homes being affected to some extent. While no rain gauges were located in this hard hit area, radar estimates indicate that around 3 of rain fell in an hour with brief rainfall rates of 6 to 7 per hour falling.||Of the four fatalities, one elderly woman and a disabled man were killed as they were…
