Thunderstorm Wind in Wayne County, Kentucky

A tree was blown down and was blocking Michigan Avenue in Monticello, adjacent to the Monticello Wayne County Park.

Eastern Kentucky experienced multiple rounds of severe weather from May 16th into the early morning hours of May 17th.

The initial round of severe weather, occurring during the morning and early afternoon, produced swaths of large to significant hail (approaching baseball size), localized damaging winds, and heavy rainfall. Notably, intense thunderstorm wind gusts impacted downtown London, tearing a roof off the Wedding Shoppe and a portion of the Copper Penny, which subsequently landed on vehicles in a nearby parking area. A lull in storm activity from mid-afternoon through early evening allowed the atmosphere to become highly unstable.

Scattered supercell thunderstorms then moved in from the west through the evening, generating multiple brief but strong to violent tornadoes across parts of eastern Missouri, southern Illinois, southern Indiana, and western Kentucky. A particularly long-lived supercell tracked east from the Ozarks of southern Missouri, intermittently producing brief tornadoes and wind damage as it moved through the southern portions of Western and Central Kentucky.

The storm's final, and most destructive, tornado touched down in Russell County, approximately 4 miles southeast of Russell Springs. Initially, the damage path was fairly narrow, in the EF-2 to low EF-3 range, as it tracked through southeast Russell County and into Pulaski County, causing significant damage to structures and trees. After impacting the southern end of Somerset, inflicting considerable damage on residential homes and the Southern Kentucky RECC headquarters, the tornado strengthened and widened. It reached EF-4 strength with estimated winds of around 170 mph as it moved toward Mount Victory. The tornado's path of devastation continued eastward through the rugged and forested terrain of the Daniel Boone National Forest, reaching a maximum width of 1,700 yards. Radar indicated that debris was lofted at least 27,000 feet above the ground. The tornado narrowed again as it approached and crossed I-75, scouring neighborhoods south of downtown London and impacting the London-Corbin Airport, before lifting about 6 miles southeast of London.

The most extensive residential damage and the largest number of casualties occurred in the Sunshine Hill community, just southwest of the London city limits. Official reports confirm 19 fatalities from this tornado, making it the deadliest tornado in the history of NWS Jackson. Seventeen of these deaths occurred in Laurel County, with one fatality each in Pulaski and Russell counties. At least 11 individuals sustained serious injuries, and an unknown number sustained less serious injuries. CHI St. Joseph Hospital in London reported treating 108 patients for injuries after the tornado. In Laurel County alone, the London mayor reported 817 homes affected, including 280 completely destroyed and 195 sustaining major damage. (For more detail, see the Official NWS Storm Survey summary and the NWS Damage Assessment Toolkit Viewer.)

Following the tornado's dissipation, the parent supercell gradually weakened as it moved eastward through Clay, Leslie, Perry, and Letcher counties, producing substantial wind damage. Separately, another strong supercell tracked from the Bluegrass region into Rowan and Elliott counties, but fortunately caused only sporadic wind damage and up to egg-sized hail. Behind these supercells, additional intense thunderstorms accompanied the passage of a cold front, primarily producing strong to damaging straight-line wind gusts.

Beyond the thunderstorms, the initial round of heavy rainfall early in the day occurred along a west-southwest to east-northeast axis, roughly from Rockcastle to Pike counties. Excessive rainfall, exceeding 3 inches in parts of Breathitt County, led to localized flash flooding. Additional isolated flash flooding occurred with the second round of thunderstorms late on May 16th and into the early morning hours of May 17th. The cumulative effect of the heavy rainfall resulted in high water at multiple river forecast points, including the South Fork Kentucky River at Oneida and Booneville, the Licking River at Salyersville, and the Levisa Fork at Prestonsburg. Minor flood stage was also exceeded at Heidelberg and Ravenna along the main stem of the Kentucky River.
