This tornado also crossed the Ohio River 3 different times! .Havover, IN / Milton, KY / Carrollton, KY EF-2... Rating: EF2 Estimated Peak Wind: 115 mph Path Length /statute/: 18.43 miles Path Width /maximum/: 500 yards Fatalities: 0 Injuries: 2 Start Date: 03/14/2024 Start Time: 01:58 PM EDT Start Location: 1 N Hanover / Jefferson County / IN Start Lat/Lon: 38.7359 / -85.4744 End Date: 03/14/2024 End Time: 02:24 PM EDT End Location: 1 NE Carrollton / Carroll County / KY End Lat/Lon: 38.6906 / -85.1418 Survey Summary: The National Weather Service in Louisville, KY in coordination with the National Weather Service in Wilmington, OH conducted a 2 day storm damage assessment survey for the supercell tornado across Jefferson and Switzerland counties of Indiana, and Trimble and Carroll counties of Kentucky from March 14. The tornado touched down on Paradise Lane off of Highway 256 on the north side of Hanover, Indiana. the tornado caused shingle and gutter damage, and a couple of large limbs down. The tornado was initially 80 mph, EF-0, with a width of 60 yards. It increased to 90 mph, EF-1, on County Manor Boulevard, taking a roof off a home with sections of the roof twisted around limbs and trees. The width increased to 80 yards. In the area by Birch St. and Ash Dr, the tornado did sporadic tree damage with a few topped and uprooted trees. The width remained at 80 yards and wind speed were EF-0, 80 mph. Next the tornado did extensive damage in Jefferson Manor subdivision. Several homes had extensive roof damage and one newer house had the roof completely ripped off. A 1500 pound brick mailbox was knocked over. Several garages sustained major damage and one outbuilding was destroyed. National Weather Service drone photography showed debris thrown up to an eight of a mile. The tornado was 110 mph, EF-1, with a width of 150 yards at this spot. The tornado crossed Indiana 56 and did extensive tree damage on South Revonah Dr. Trees were snapped, uprooted, and twisted in multiple directions. Witnesses saw the tornado, had photography, and heard a "loud wind" and had their ears pop. Wind speeds of 90 mph EF-1, with a width of 200 yards. There were also some uprooted trees along River Bottom Road. Many thanks to those who shared some of the most dramatic river tornado video; which shows the tornado cross the Ohio River, sucking up water, and throwing it in all directions. The tornado crossed the Ohio River between River Bottom Road on the Indiana side and Coopers Bottom Road on the Kentucky side, just south of the Clifty Creek Power Plant. EF-1 damage continued to the east along Coopers Bottom Road, and up the steep hillside just to the south of the road where numerous hardwood trees were uprooted or snapped. A large portion of the funnel actually remained on the Ohio River during this stretch (confirmed by video and damage patterns), roughly paralleling the river as it is oriented more west to east between Madison, IN and Milton, KY. The tornado continued to do high-end EF-0 and low-end EF-1 damage along Coopers Bottom Road and US Highway 421 as the southern fringes of the funnel scraped the Ohio River shoreline on the Trimble county side of the river, and snapped trees along the 800 foot cliffside above Milton, KY. Light trailers were flipped over, but remained intact at the River Park Campground. In addition, some hardwood trees were snapped. EF-0 and EF-1 damage continued as the southern half of the funnel entered Milton, doing roof and structural damage to numerous homes and businesses. In addition, numerous hardwood trees were either snapped or uprooted. Just east of downtown Milton, a large brick home under renovation had a large section of its back wall blown out, with estimated winds of 105 mph, which was a bit stronger than points to the west. Noted strengthening occurred over the next mile eastward as more concentrated medium to high end EF-1 damage was noted. Evidence that the center of the tornado was still out over water at this point was strong, given that the downed trees were facing toward the river in almost all instances from Milton eastward until Paradise Point along Highway 36 about 1 mile east of downtown Milton. The center of the tornado finally came on shore at Paradise Point and was immediately at low-end EF-2 strength as several large campers and a motorhome were demolished. One tri-axle camper weighing well over 10,000 lbs was rolled and thrown over 100 yards to the ESE, with debris scattered much farther downstream. Just across Highway 36, a well-built single family residence sustained major roof damage as half of the structure was removed by the tornado. This was also rated at EF-2 strength with winds of 115 mph. Just east of that house, a semi trailer was rolled, a large barn was completely collapsed and shifted, and nearly every tree was snapped in a grove. This was a notable uptick in intensity from areas to the west as snapped trees were more sporadic in those areas. This was more justification for the increase to EF-2. It was at this point that a clear northern portion of the tornado track became evident as downed trees along Highway 36 were laying in a SE direction, pointing inward toward the center of the circulation. It was unclear just how wide the tornado was as it crossed through Milton, since half of the funnel was out over water, however the tornado was around 500 yards wide (rougly a third of a mile) by the time it reached the Trimble/Carroll county line at North Spillman Lane. EF-1/EF-2 intensity remained here as a large span of telephone polls were snapped. There was extensive tree damage just inside of Western Carroll county, with the tornado maintaining 115 mph, EF-2, strength before weakening across the rugged Fairview ridge. There was one large barn that had extensive roof paneling damage, and a door blown out, along Hampton Road. Wind speeds were 90 mph, EF-1. There was a lot of topped tree damage along Locust Creek and Kentucky State 36. Wind speeds were 85 mph, EF-0. The tornado crossed the Ohio River for a second time, and increased significantly at the Indiana 56 RV park and campground. The tornado snapped dozens of trees. The 400 yard wide twister knocked over several RV trailers, and lifting them in the air and wrapping two around trees. We looked up owner's manuals to determine that actual weight of the various types of trailers. One trailer in particular was a 46-footer, and weighed about 14000 pounds, and was knocked over and moved 5 inches. Numerous boat ports, had anchor supports pulled out of the ground, including several buried in a foot of concrete. Debris from the RV park was thrown onto Highway 56 and well beyond into the trees on the north side of the highway. Outbuildings and small barns were destroyed. Wind speeds at the RV Park were 115 mph, EF-2. The tornado crossed in Switzerland county, damaging three barns along Green Valley Road. All the barns sustained significant roof panel damage. Some trees were uprooted and had lots of topped and snapped trees as well. As the survey team drove east on 56, you could see extensive tree damage up on the north hillside. The tornado did extensive power pole and powerline damage, along with tree damage near the intersection of Patton Hollow Road on Indiana State 56. Wind speeds were 90 mph, EF-1, with width of 150 yards. The tornado crossed the Ohio River for a third time, going back into Carroll county just east of Carrollton on US 42. The tornado was very narrow and produced some sporadic tree damage before lifting. Wind speeds were 68-75 mph, EF-0. The Kentucky Mesonet site 2E of Carrollton measured 68 mph as the weakening tornado lifted. The National Weather Service would like to thank Emergency Management in Indiana and Kentucky, and Carroll county fire chief Robert Hoffman for all of their assistance. In addition, thanks to NWS Wilmington, OH and the Kentucky Mesonet for their assistance with additional data. && EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0.....65 to 85 mph EF1.....86 to 110 mph EF2.....111 to 135 mph EF3.....136 to 165 mph EF4.....166 to 200 mph EF5.....>200 mph NOTE: The information in this statement is preliminary and subject to change pending final review of the event and publication in NWS Storm Data. $$ SCHOETTMER/GORDON
