The storm has disrupted daily life. Many Tennessee hospitals suspended services due to water supply issues and flooding. The Great Smoky Mountains National Park urged visitors to reschedule trips due to "historic flooding." In Asheville, North Carolina, gas shortages, power outages, and lack of cellular service have left the city isolated. Officials are working to set up hubs to distribute food and water to affected residents. Photo credit: @CowboysYall/X
