| March 2012 | Tornado (EF4) | Freddricksburg | 5 killed, $2,000,000 | This EF-4 tornado that ultimately stayed on the ground for 49 miles across several counties touched down just south of Fredricksburg. Several trees were snapped off with estimated EF-1 damage along a path of 30 yards wide along the south fork of the Blue Lick River. After crossing farmland, the tornado widened and intensified quickly, toppling a high tension metal power structure near the intersection of Homers Chapel and Fredricksburg Roads. Damage at that location was consistent with 130 mph winds. ||High tension wires were downed and trees snapped along West End Road just north of Shanks Hill Road. The tornado continued to intensify as it crossed State Route 135 at Dutch Creek Road, ripping large chunks of 3 inch thick asphalt from a section of roadway and depositing large pieces up to 30 yards away, with smaller chunks of pavement found a quarter of a mile downstream. Just east of State Route 135, tremendous tree damage began. At this point, the tornado widened to around 200 yards. As the tornado crossed Trainer Lane and Route 335 towards Robbs Lane, widespread tree and structural damage indicated EF-2 to EF-3 damage. At this point, the damage path began to widen to one third of a mile. ||After crossing Highway 60 just south of New Pekin, tremendous structural damage was surveyed. A large well-constructed factory building was cleared to its foundation slab with numerous anchoring bolts bent and stripped. Debris from this building was observed up to three quarters of a mile downstream. Large power poles were snapped. Another metal out building on the edge of the circulation had sheeting pulled off, apparently from the force of inbound winds towards the circulation. In this area 5 people were killed in a mobile home. Damage suggested an EF-4 tornado with a width of three to four tenths of a mile and estimated winds of 170 mph. ||The tornado then traveled along the border between Washington and Crawford counties where it caused widespread destruction southeast of Hurst and along East Daisy Hill Road in the county. Here, a well constructed one story brick home at the top of a ridge was completely destroyed with no wall left standing. Witnesses described the funnel as a black wall. A heavy semi trailer cab was blown from this house and landed near another destroyed brick home. Damage to these homes suggested EF-4 winds of 170 mph. Near the intersection of East Daisy Hill and Williams Knob Roads, a home and two anchored double wide trailers were destroyed. A car was lifted and fell 100 yards away from its original driveway. The width of the damage path along the county line was up to one half mile, although the concentrated damage path was much more narrow. Overall, the twister traveled 17 miles in Washington county, felling thousands of trees in addition to destroying scores of buildings. |

| March 2017 | Tornado (EF1) | Saltillo | $150,000 | A NWS storm survey, in conjunction with Washington County Emergency Management concluded that the tornado touched down and was embedded in a larger field of straight-line winds. The path length was 5.8 miles with a max width of 100 yards for the tornado, however the overall straight-line wind path width was close to a mile wide in spots. The most intense tornado damage happened shortly after touchdown, where over 50 healthy hardwood trees had snapped trunks with no foliage. In addition, an outbuilding lost part of a roof, and debris struck a residence causing cracked masonry and dented drywall on the inside of the structure. Maximum wind speeds of 100 mph were estimated in this area. The tornado continued eastward where more homes experienced minor roof damage, trees were uprooted, and a large outbuilding was nearly destroyed. After crossing Cave River Valley Rd and White River Rd, the tornado took out nearly 50 softwood trees. Farther east, over 100 hardwood and softwood trees were uprooted and snapped, and notable convergence was observed. After driving a 4X6 post through the roof of a home near Hunter Rd, the tornado continued east to Prowsville Ridge Rd, where an uptick to 90-95 mph intensity was noted. Another stand of nearly 50 hardwood trees were uprooted and snapped, along with significant damage to a porch and roof of a home.
