Boyle County

Every recorded tornado

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

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 KY GS (4).

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 small tornado touched down from a supercell thunderstorm on top of a tall hill along Highway 1822 and quickly destroyed one large barn used to store hay, severely damaging another medium sized barn, and destroyed fencing. The tornado did some damage to a grain silo along with some tree damage. An antique horse sled was picked up and moved about 10 feet. ||The tornado briefly lifted in a valley before striking a residence on the east side of Highway 1822 and lifting the roof off a family residence. Insulation from the roof was thrown eastward and also rotated back and covered the back of the house. ||Further east on Webster Rd, another one story family residence sustained…

   There were numerous reports of flooded and closed roads countywide. Five homes were evacuated due to rising water in a subdivision of Perryville.

9. May 8, 2009Flash Flood$20,000
   National Weather Service narrative

   A long-lived bow echo that had produced widespread wind damage over southern Illinois moved east into Kentucky during the late morning hours. As it moved east, the system encountered a strengthening low-level jet across the Ohio Valley, which helped modify the motion of the line, resulting in training storms of extremely heavy rain that caused flash flooding. Individual storms developing ahead of the line continued to produce damaging winds, with two storms producing tornadoes, before the main area of convection moved through. ||NWS damage surveys determined the tornado in south-central Kentucky to be EF-1 in intensity, while the east-central Kentucky was ranked as a strong EF-3.…

    The public reported that several mobile homes were flooded.

1. Storm Events records before 1996 cover only tornadoes, thunderstorm wind and hail. Damage figures are as reported by the National Weather Service at the time, not adjusted for inflation.
