Chattanooga Faces Severe Weather and Sinkholes
Severe weather conditions and sinkholes are causing major disruptions across East Tennessee, particularly in Chattanooga, where a large sinkhole has closed Heritage Landing Drive under Veterans Bridge. This closure is blocking the main entrance into the neighborhood, leaving residents awaiting updates regarding estimated repair timelines from city officials.
Currently, residents in the Knoxville region are cautioned to seek higher ground as a flash flood warning remains in effect until 2 p.m. today. This warning has arisen due to heavy rainfall that began on August 12, continuing to create hazardous flooding conditions. Thunderstorms across the area are producing extensive rainfall, further increasing the risk of flooding.
The National Weather Service has issued flash flood warnings for several counties, including South Central Anderson County, Northern Blount County, West Central Jefferson County, Knox County, Northeastern Loudon County, Southeastern Roane County, and Northern Sevier County. According to data from McGhee Tyson Airport, 1.4 inches of rain fell in just three hours by 10:53 a.m. today, further contributing to local flooding.
In Knoxville, numerous streets were reported as flooded early this morning, and with more rain on the way, officials express concern for worsening conditions. Knox County officials are actively monitoring flood-prone areas and may implement road closures and detours if necessary. Jim Snowden, Knox County’s director of engineering and public works, reported that flooding is also affecting various construction sites in the area.
Interstate 40 experienced significant traffic delays due to crashes caused by the storm, particularly in Sevier County and East Knox County. As of 11:25 a.m., approximately 1,400 utility customers across West Knoxville were without power, as indicated by the Knoxville Utility Board outage map.
In addition to ongoing weather challenges, severe flooding in Chattanooga and Northwestern Georgia has resulted in three fatalities and one missing person. Although Interstate 24 was temporarily closed due to flooding, it has since reopened as water levels receded. Notably, the National Weather Service recorded 6.42 inches of rain at Chattanooga Airport in one day, marking the second-highest total for a single day in the city’s history.
Further complicating the situation, a sinkhole has also formed on Highway 111 in Sequatchie County due to an underground pipe failure, impacting traffic flow until necessary repairs can be completed. In Chattanooga, crews have filled a sinkhole that emerged in a Walgreens parking lot; however, concerns remain due to a leaking pipe, for which the responsibility for repairs lies with Walgreens.
Geologist Amy Brock-Hon has indicated that the region’s wet weather could be weakening the limestone, potentially contributing to the formation of these sinkholes. Although a major drainage improvement project had been previously conducted near the Walgreens site, city officials have stated that the recent sinkhole issues are not related.
