Robertson County

Every recorded tornado

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

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 (6).

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.

Costliest events since 1996

1. Mar 1, 1997Flash Flood$500,000
   National Weather Service narrative

   Estimated rainfall of 6 to 8 inches across the county in less than 36 hours caused area creeks and streams to rise out of their banks. Numerous roads were flooded.

2. Sep 14, 2008High Wind, Robertson$274,000
   National Weather Service narrative

   Strong winds of 40 to 50 miles per hour were sustained for several hours. Gusts over 60 mph were common. Widespread damage occurred across the region, from trees being blown down on powerlines to significant structural damage.

3. Jan 6, 1996Winter Storm, Robertson$200,000
   National Weather Service narrative

   The Blizzard of '96 developed near the Gulf Coast and moved up the East Coast. This massive system brought the greatest snowfall from one storm to Greater Cincinnati/Northern Kentucky airport, as well as the greatest 24 hour snowfall. Total snowfall from this storm at the airport was 14.3 inches, while in a typical entire season this location normally receives only 23 inches of snowfall. Many homes and business experienced partial or total roof collapses due to the weight of the snow. Road conditions remained hazardous in some locations for many days. Many people believed that this was the worst winter storm since the Blizzard of '78.

4. Jun 29, 2012Thunderstorm Wind$90,000
   National Weather Service narrative

   One roof was completely ripped off of a barn with numerous reports of other barns also damaged due to thunderstorm winds. Trees were downed across the county.

5. May 24, 2026Flash Flood$60,000
   National Weather Service narrative

   A culvert and part of a bridge were washed out, making the roadway impassable.

6. Apr 8, 2020Thunderstorm Wind$60,000
   National Weather Service narrative

   Trees, limbs and electric lines were downed and power was out throughout the county. There were multiple reports of damage to roofs.

7. Jun 3, 2008Thunderstorm Wind$40,000
   National Weather Service narrative

   Several homes sustained roof damage and the loss of vinyl siding to the northeast of Mount Olivet. One home has a second story window with broken glass with the window frame blown inwards. Several barns had outer walls collapsed with the loss of metal roof panels. These barns appeared to be older and poorly constructed. Numerous trees were snapped at the trunk or completely uprooted. Investigation determined this damage was caused by a microburst with maximum winds at 85 mph.

8. Apr 8, 2020Tornado$25,000
   National Weather Service narrative

   The tornado first touched down north of Mt. Olivet and damaged structures along Highway 165 north of town, and then east across Brierly Ridge Road. A state highway barn was damaged. Tree damage was also seen along the path damage.

9. Feb 1, 1996Cold/Wind Chill, Robertson$20,000
   National Weather Service narrative

   Arctic high pressure brought the coldest air of the season to the Ohio Valley. Greater Cincinnati\Northern Kentucky airport broke its record low on the 4th with 11 below zero. The airport also set its lowest maximum temperature records of 7 and 6 degrees on the 3rd and 4th respectively. The extreme cold was entrenched for 5 days, freezing and bursting numerous water pipes. AAA motor club had an extremely high number of calls to start cars due to the cold wave.

10. Feb 18, 2000Flash Flood$15,000
    National Weather Service narrative

    Many hours of heavy rainfall caused the closing of State Route 168. Also, rising water forced the evacuation of a retirement home.

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.
