McLean County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within McLean 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 (3).

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.

1. Jan 26, 2009Ice Storm, Mclean$10.9 million
   National Weather Service narrative

   This historic, prolonged ice storm was called the biggest disaster in modern Kentucky history by the governor of Kentucky. The storm produced at least one inch of ice across western Kentucky. Locally very destructive icing around 1.5 inches occurred from the Mississippi River counties east across Paducah and Madisonville to Owensboro. This resulted in unprecedented damage to utility infrastructure in western Kentucky. One hundred percent of residents in the hardest-hit counties from the Mississippi River to Madisonville were affected by power outages. A utility company serving areas from Ballard to Livingston Counties reported that 20 percent of its system had to be rebuilt. The…

2. Sep 14, 2008High Wind, Mclean$4.5 million
   National Weather Service narrative

   Frequent wind gusts from 60 to nearly 80 mph caused widespread damage in western Kentucky. The low pressure center that was the remnant of Hurricane Ike raced northeast at 40 to 50 mph across Missouri and Illinois. The center passed between Carbondale and St. Louis on its way toward the northeastern states. The rapid speed of the low pressure system contributed to this high wind event. ||Several counties reported hundreds of structures sustained roof and siding damage. Other counties reported dozens of damaged structures. The county of Crittenden alone estimated 1,500 homes sustained some degree of wind damage. Extensive tree damage occurred. Thousands of trees were uprooted and…

3. Mar 1, 1997Flood, Mclean$4.5 million
   National Weather Service narrative

   Historic flooding occurred along the Green River as a result of widespread rainfall between 5 and 10 inches across central and western Kentucky. Virtually the entire town of Rumsey was evacuated before it was inundated by the Green River. About 20 percent of Calhoun was underwater, and small parts of Livermore were affected.In Daviess County, backwater from the Green River slowed drainage of Panther Creek, causing parts of Owensboro to flood. Many schools were out for one to two weeks. The National Guard was mobilized to help with looting prevention, rescue efforts, and sandbagging. Daviess County was especially hard hit due to the combined effects of major flooding along the…

4. May 1, 2011Flood$3.0 million
   National Weather Service narrative

   Major flooding continued on the Green River from April. At the Calhoun river gage, the flood crest of 34.01 feet on the morning of May 7 was just a few inches lower than the 1997 flood. This 2011 flood crest was the sixth highest on record. Green River floodwaters inundated the entire community of Rumsey and about 20 percent of Calhoun. A very small part of Livermore was flooded.

5. Jan 23, 2002Tornado$1.0 million
   National Weather Service narrative

   Top wind speeds in this F-2 tornado were estimated near 120 MPH. The damage path extended from the extreme northwest side of Calhoun to the extreme northeast side of town. A total of about 53 buildings were damaged or destroyed, of which 43 were homes and 10 were businesses. At least one home and one business was destroyed, 5 houses received major damage, and 4 businesses including a church and daycare center received major damage. The business that was destroyed was a TV antenna/satellite service on Kentucky Highway 81 at the northern city limit of Calhoun. Most of the remainder of the structures received minor damage. In addition to the damaged homes and businesses, barns, grain…

6. Mar 1, 1997Flash Flood$800,000
   National Weather Service narrative

   Routes 231, 81, and 136 were under water in places.

7. Feb 13, 2025Flood$500,000
   National Weather Service narrative

   River levels rose into flood following a rainy couple weeks in the Green River basin, with a major rainfall event of nearly half a foot of rain on the 15th leading water levels to surge at Calhoun to major flood. Nearly the entire town of Rumsey sustained some amount of water intrusion. Lower Calhoun flooded as well, along with many thousands of acres in the Island and Jewel City areas. Many homes and businesses along the river had flooding issues develop. River levels remained in moderate flood as flooding continued into March.

8. Feb 11, 2008Winter Storm, Mclean$500,000
   National Weather Service narrative

   Low pressure developed over the southern Plains, spreading widespread heavy precipitation across western Kentucky. At the same time, high pressure over the upper Ohio Valley produced a cold easterly wind flow. The result was a crippling ice storm. Around one inch of ice caused extensive damage across parts of western Kentucky, along and north of a line from Paducah to Madisonville. Many of those same areas received two to four inches of sleet and snow. Numerous trees and power lines were brought down, knocking out power to many thousands of homes. Power outages lasted up to a week. Emergency shelters were established in several counties (including Livingston, Crittenden, and…

9. Oct 18, 2007Tornado$400,000
   National Weather Service narrative

   Twelve to fifteen farm buildings were damaged. Six to eight barns were destroyed. One home received heavy damage. Three to four more houses received minor damage. A garage and several vehicles were destroyed. A pontoon boat loaded on a trailer was moved 15 to 20 feet. Numerous trees and power lines were down. The funnel was photographed by a resident of the Beech Grove area. Peak winds were estimated at 120 mph. The average path width was 300 yards. The tornado continued into Daviess County.

10. May 11, 2003Tornado$400,000
    National Weather Service narrative

    One home was destroyed, and one home was severely damaged. A mobile home disintegrated, with the frame found one quarter mile away. Several barns or sheds were destroyed. Two vehicles were rolled. Numerous trees were uprooted, and some were blown some distance. The damage path began about one quarter mile west of Highway 81 in the south end of Sacramento, then extended eastward. The two injuries were relatively minor. Peak winds were estimated near 170 MPH.

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.
