Tornado - Louisville, KY
Jefferson County

Date	7/4/2024
Time (Local)	1:27 PM - 1:28 PM EDT
EF Rating	EF-1
Est. Peak Winds	95 mph
Path Length	0.51 miles
Max Width	170 yards
Injuries/Deaths	0/0
Summary: The NWS sent a survey team after an area of concentrated damage occurred along a narrow squall line in NW Jefferson County. An EF1 tornado was discovered to have caused initially a broad swath of damage and then it tightened up before lifting. The damage began to a Baptist Fellowship Center just north of Woodland Ave along Catalpa St. The nearby church sustained shingle damage, but also had some window damage on the more protected north facing side of the building. South of Woodland Ave, a witness saw twisting motion, and there black walnut tree branch fell to the west onto a neighbors house and a tree from that home fell onto his truck. As the tornado tightened up, several tree branches fell onto vehicles and structures. A few bigger trees were uprooted as well, including one that pulled down some power poles as it fell. In another place, the tornado pulled back part of a roof on a two-story residence. Farther east, the vinyl siding was stripped off a north-facing wall of another 2-story residence. As the tornado continued east and east southeast, crossing Hwy 1934, it narrowed quite a bit, causing more isolated tree damage before it lifted just east of 23rd Street and north of Standard Ave. The National Weather Service would like to thank the Louisville Gas and Electric crews that assisted with finding damage points and Jefferson County Emergency Management for focusing the survey where the heaviest damage occurred.
