2024-09-27 · Montgomery, Kentucky

Event narrative

Two weather stations, a personal weather station 1 miles northwest of Ewington and the AWOS at the Mount Sterling Airport, reported peak wind gusts of 52 mph at 1204 PM EST and 48 mph at 1215PM EST, respectively. In spite of these gusts not attaining warning criteria, widespread wind damage was reported by NWS employees around the county. At 1030 AM EST, an NWS employee reported a tree blown down onto and blocking High Street one block east of the courthouse. At least 2 trees were blown down along US-460 near Camargo and multiple trees were blown down onto KY-646 at the intersection with KY-213, blocking the highway and involving the power lines. Another large hardwood, approximately 18-inch diameter, was snapped off at its base at the intersection of KY-213 and Shelby Lane. Additionally, a large yard tree fell through the main section of a home in Mount Sterling near the Maysville Community and Technical College. Approximately half a dozen consecutive power poles were snapped along US-460 immediately southeast of the intersection with KY-686. Finally, a large yard tree was uprooted and fallen on a livestock fence on the southwest side of US-460 adjacent to Hartzler Door and Gate.

Wider weather episode

The remnants of Hurricane Helene brought widespread wind damage to much of Kentucky on Friday, September 27th. Helene initially made landfall along Florida's Big Bend region during the late evening of Thursday, September 26th as a fast-moving Category 4 hurricane. The hurricane's rapid forward movement did not give the system much time to weaken by the time the system's tropical rain bands spread across eastern Kentucky by early Friday morning. As the dissipating core of the hurricane approached, northeast to easterly winds intensified rapidly across eastern Kentucky between 6 AM and 10 AM EDT. Wind gusts peaked at around 12 PM, ranging from 35 to 60+ mph at most locations. The strongest wind gust in eastern Kentucky, 64 mph, was reported atop Koomer Ridge just west of Campton. The combination of full foliage on the trees, saturated soils, and an atypical wind direction led to many uprooted trees, resulting in blocked roads and extensive power line damage. Isolated instances of structural damage were also observed.

Power outages across the Commonwealth numbered over 200,000 customers, the vast number of which were in eastern Kentucky, by the time the winds had diminished Friday afternoon. Kentucky Power alone reported at least 137 broken power poles and 734 spans of downed wire. Clark Energy reported over 100 broken poles in their service area. Jackson Energy reported 71 broken power poles and close to 400 spans of downed wire. Power restoration efforts continued for days after the storm, as some customers in the hardest hit locations did not see their power restored until October 3rd. There were also several reports received of trees falling on homes. Unfortunately, one injury was reported in eastern Kentucky, due to a tree falling on a home in the community of Cawood (Harlan County). The winds also put a damper on the festivities at the World Chicken Festival in Laurel County and the Sorghum Festival in Morgan County for most of the day.

While 5-day rainfall amounts exceeded 5 inches across portions of far southeastern Kentucky (locally up to 7.74 inches atop Big Black Mountain), weeks of unusually dry weather had led to the development of abnormally dry to severe drought conditions across most of the Eastern Kentucky Coalfields. Consequently, when a sluggish frontal boundary and upper level low became quasi-stationary across the region earlier in the week (around September 23rd and 24th), the repeated rounds of rainfall were highly beneficial for alleviating the drought. In fact, the additional rainfall from Helene only led to minor instances of stream and street flooding.
