Humphreys County/Waverly Areas near the town of McEwen received the most rainfall from the event, as much as in some places. Much of the floodwater exited the area westward along Trace Creek, causing large swells which inundated much of Waverly, just to the west. Waverly had received comparatively less rainfall than McEwen but was flooded by runoff from upstream. In Waverly, many homes and businesses became flooded after 6 a.m. CDT, prompting evacuations and water rescues. Waverly Elementary School and Waverly Junior High School were both inundated with several feet of water, and the Humphreys County 911 center was rendered inoperable by the flooding. Officials in Waverly commented that had the flood occurred during a weekday, the schools would have been full of students and would have been impossible to evacuate in time. Roads into Waverly became impassable, with crews trying to perform rescue operations unable to reach some areas. Cell phone service in the area was disrupted as well, complicating initial response and recovery efforts. The county water system was reported down by the Humphreys County Sheriff, Just west of town,
Waverly Central High School was impacted, with the football field, stadium, weight room, and locker room all being destroyed by the flood. In Humphreys County, at least 509 homes were impacted by flooding, 271 of which were completely destroyed. Eight public facilities and 44 commercial properties sustained damage, many of which were in downtown Waverly. The Humphreys County sheriff commented: "We have well over 125 homes that are just gone – off the foundation, twisted, turned, or just gone." Ten bridges in the county remained closed well after the event as a result of flood damage, including the westbound U.S. 70 bridge over Trace Creek, the TN 230 bridges over Hurricane Creek, and seven county-owned bridges across Trace Creek, Blue Creek, Hurricane Creek, Little Hurricane Creek, and Bateman Branch. However, the State Route 230 bridge over the Piney River remained closed, requiring extensive repair.
