Knoxville – Severe storms swept through East Tennessee on the afternoon of September 4, 2025, causing significant damage and widespread power outages, particularly in Knoxville. The National Weather Service (NWS) office in Morristown confirmed that the damage was primarily due to straight-line wind gusts characteristic of severe weather conditions.
The storms, which were part of a larger weather system affecting millions from Texas to Pennsylvania, brought destructive winds, hail, and localized flooding to various areas including Nashville, Bowling Green, and Charleston. As a precaution, severe thunderstorm watches were issued across Tennessee and the Ohio Valley, with the most intense activity forecasted from northern Mississippi to Ohio.
In Knoxville, Skyranch Airport reported considerable damage to its hangars, with only one escaping the effects of the storm. Video footage revealed the scale of the destruction. Strong wind gusts reached up to 60 mph, and quarter-sized hail was reported during the storms, which marked a continuation of severe weather over two consecutive days.
The storms prompted official warnings for several counties including Knox, Anderson, and Roane. Tornado warnings were in effect until 1:30 PM EDT as authorities advised residents to stay indoors, away from windows, and prepare for potential power outages given the severity of the conditions. More than 7,700 customers experienced power outages in the Knoxville area, according to reports from the Knoxville Utilities Board and Oak Ridge Electric.
Residents across the affected regions were cautioned to seek shelter as downed power lines and tree damage were prevalent. Although some localized flooding occurred, officials indicated that the destruction was largely associated with wind rather than tornado activity. A forecasted second cold front is expected to bring additional rain on September 6, while September 5 is anticipated to be dry.
In summary, the severe storms on September 4 resulted in substantial destruction in Knoxville and surrounding areas, leading to power outages affecting thousands, warnings of dangerous weather conditions, and the likelihood of continued adverse weather as new atmospheric fronts develop.
