Clay County

Every recorded tornado

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

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 (531), NASA (1), USGS Conterminous (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.

   National Weather Service narrative

   Flash flooding that occurred on April 16 and 17 developed into widespread river flooding in the Kentucky River basin on the 17th. An intial crest occurred at most locations on the 17th or 18th, but additional heavy rains from the 18th into the 19th resulted in a second crest on either the 19th or 20th. Crests were 4.3 feet above flood stage at Jackson, 5 feet above flood stage at Booneville, and 5.5 feet above flood stage at Hazard. Numerous roads were flooded, and some homes and business were also affected by high water. In Hazard, Main Street had to be closed for a time on April 19. In Jackson, Panbowl Lake backed up, and flooded the basements and lower levels of several homes…

2. Apr 16, 1998Flash Flood$200,000
   National Weather Service narrative

   Severe thunderstorms on the evening of April 16 produced wind damage, hail, and tornadoes. At Windy in Wayne County, a barn was damaged by thunderstorm winds, and a spotter south of Brodhead in Rockcastle County estimated wind gusts of 60 to 70 mph. East of Hazel Patch, in Laurel County, a trailer was damaged by thunderstorm winds. Two tornadoes also touched down, one in Rockcastle County, and another that moved from Wayne into McCreary County. The thunderstorms also brought extremely heavy rain, and this resulted in widespread flash flooding from the 16th to the 17th. Numerous roads were flooded, and some roads and bridges were washed out. There were also several massive mud and…

Approximately 20 county roads and 15 bridges were damaged as nine people were forced to leave their homes.

10. Apr 18, 1998Flash Flood$50,000
    National Weather Service narrative

    From April 18 to 19, most of southeast Kentucky received 1 to 3 inches of rain, but some spots received 3 to 5 inches. The heavy rain resulted in widespread flash flooding, small stream flooding, and eventually river flooding. Numerous roads were flooded, or blocked by mud and rock slides. Flooding was especially severe along the Right and Left Forks of Beaver Creek in Floyd County. Approximately 229 homes were affected by the flash flooding in Floyd County, and numerous residents had to be evacuated.
