Tornado #5 - Lake Dreamland, KY Floyd County, IN - Jefferson County, KY Date 5/7/2023 Time (Local) 8:57 - 9:03 AM EDT EF Rating EF-1 Est. Peak Winds 100 MPH Path Length 4.8 miles Max Width 200 yds Injuries/Deaths 0/0 Summary: The National Weather Service conducted a storm damage assessment survey in southern Floyd County IN and western Jefferson County KY from the storms mid-morning Sunday. The first area of damage was at The Sporting Club at the Farm on State Road 111.  Two large barns had significant roof damage, there were shingles and soffit damage to a large well-built house. Of significance, a 110-pound storm cellar door was sucked out and thrown almost 100 yards to the east.  There were 3 trees uprooted and facing from north to an easterly direction.  The 600-pound sign for the sporting club was lifted up and moved to the north several feet. The tornado crossed 111, and snapped and twisted over a dozen trees along the west side of the Ohio River.  Because of the 110-pound bolted tornado shelter door being sucked out, the tornado rating increased from 95 to 100 mph. The width was 100 yards wide.   The tornado continued near Five Mile Lane and River Road in Floyd County along the Ohio River where shingles were lost on a residence and a barn garage received significant roof damage where the metal panels were peeled off. The tornado then crossed the Ohio River into Kentucky in the Lake Dreamland area of West Louisville in western Jefferson County. Significant tree damage was observed along River Front Drive and continued along Kale Dreamland Road where several hardwood trees were snapped or uprooted, along with many large branches down.  The tornado continued along Kramers Lane toward Van Winkle Drive, where damage appeared to be sparser with large branches down in some isolated areas. Very isolated areas of large branches down continued through the Heatherfield and St. Dennis neighborhoods (and across I-264 Watterson Expressway) and toward the Louisville Memorial Gardens. Along Lynn Lea Road, the tornado regained strength and continued through homes along Kendall Lane west of 31W Dixie Highway. Trees were snapped heading on the east side of Hunters Trace neighborhood. Significant tree damage was observed along Malcolm Road just north of Gagel Avenue. Several hardwood trees were uprooted or snapped with damage consistent with 94 mph winds in this location. No visible damage was observed to the southeast beyond Gagel Avenue where the tornado ended. The National Weather Service would like to thank Jason Mauch, Deputy Director Floyd County Emergency Management and Gavan Hebner, Director Clark County Emergency Management for their assistance with the survey. The National Weather Service would also like to thank Jefferson County EMA and the helpful citizens in the damage path for their assistance with the completion of the survey.   Track Map

Tornado #6 - Shelbyville, KY Shelby County Date 5/7/2023 Time (Local) 9:25 AM - 9:26 AM EDT EF Rating EF-0 Est. Peak Winds 75 MPH Path Length 0.6 miles Max Width 30 yds Injuries/Deaths 0/0 Summary: The National Weather Service conducted a storm damage assessment survey in Shelbyville from the storms mid morning Sunday. The Valero gas station sign was pushed to the east and towards Highway 55 (Taylorsville Rd), with some of the sign damage thrown across Hwy 55 onto Pearce Industrial Road. The next damage was at the Black and Decker plant off of Harry Long Rd. There was significant roofing damage across several portions of the roof to be lifted and thrown 30-40 yards. All of the debris from the roof was pushed to the east southeast. There were 3 business and home videos that all faced towards Black and Decker warehouse, where you can definitely see a narrow funnel in contact with the ground. This was key to this tornado rating as drone photography showed almost no damage between the Valero Gas Station and B & D roof structure. There was not a single tree snapped or twisted and a large cell tower right in its path had no damage. Based on the videos and the damage to the B & D roofing structure, the survey team came up with a EF 0 75 mph rating, with a width of 30 yards. The survey team drove across several intersecting roads within a 2 mile radius along old Finchville Road over to Zaring Mill Road and found no other damage. The National Weather Service, would like to thank Chris Spaulding from Shelby County Emergency Management for his assistance . Track Map
