2021 Tennessee floods

Between midnight and 10:00 am CDT on Saturday, August 21, 2021, very heavy rainfall resulted in widespread flash flooding across western Middle Tennessee, including the town of Waverly. During the event, much of a five-county area received up to a quarter of normal annual rainfall in under twelve hours, as much as 10 to 15 inches (250 to 380 mm). In a situation described as catastrophic, Waverly was severely damaged by floodwater, with hundreds of homes and dozens of businesses destroyed and swept away. Numerous people became trapped, leading to widespread water rescues. The event resulted in 19 fatalities in Waverly, with another in nearby Hurricane Mills, and is regarded as one of the worst natural disasters in Tennessee history. The event broke the 24-hour rainfall record in Tennessee, with over 20 inches (510 mm) of rain falling in McEwen. Flooding also occurred in parts of western Kentucky, but to a much lesser extent.
