KNOXVILLE, Tennessee
The Tennessee Valley Authority (TVA) effectively managed the impacts of Hurricane Helene, significantly mitigating potential damage across regions in east Tennessee. The storm made landfall on September 26, 2024, and heavy rainfall began affecting areas in east Tennessee and North Carolina by September 27. Thanks to advance preparations and strategic actions, TVA’s efforts are estimated to have prevented approximately $406 million in potential damage, excluding loss of life.
TVA has been monitoring storms like Hurricane Helene from the moment they begin brewing. Although the storm was initially projected to stay west of east Tennessee, TVA’s proactive management was essential due to the unpredictable nature of hurricanes. In anticipation of inflows caused by Hurricane Helene, TVA staffed its River Forecast Center accordingly, bringing in extra personnel to handle the increased rainfall and localized issues.
To prepare for hurricane season, TVA lowers reservoirs in late summer, which holds back runoff water and helps prevent flooding. This strategy is considered vital for flood protection by TVA’s dams, as noted by Darrell Guinn, senior manager of the TVA River Forecast Center. The storm brought days of heavy rainfall that could have led to more severe flooding without these preparatory measures.
Areas such as Lenoir City, Chattanooga, Elizabethton, and Knoxville were identified as significant locations that benefitted from TVA’s advanced planning and rapid response capabilities during and after the storm. The flood management techniques successfully kept the water levels controlled and minimized the effects of the storm.
Despite the effective flood management, communication during the storm proved to be challenging due to downed trees and power lines, which hindered the flow of information and required an increased reliance on emergency responders. The lessons learned from Hurricane Helene emphasized the importance of communication and having redundant systems in place for emergency preparedness.
TVA continues to track storms regardless of their projected paths, recognizing the unpredictable nature of such weather events. This proactive approach enables TVA to respond more effectively and implement measures to protect the communities it serves.
