The National Weather Service in Morristown has delivered a grim forecast for the Tennessee Valley and Southern Appalachians, as the remnants of Hurricane Helene promise a deluge and high winds through Friday evening. According to the National Weather Service in Morristown, tropical storm conditions are possible today, with heavy rain and thunderstorms expected before 2 p.m. and a slight chance of showers and thunderstorms following between 2 p.m. and 3 p.m., coupled with patchy fog through noon.
Amid saturated soils, the probability of flash flooding is high, with new rainfall amounts between a quarter and half of an inch feasible; tropical downpours primarily in the morning hours could further amplify this threat, and already vulnerable areas must brace for an additional 2 to 4 inches of rain—a Flood Watch remains in effect through Friday afternoon for parts of east Tennessee and southwest Virginia, raising fears of rivers and streams breaching their bounds and flooding low-lying regions, with strong winds exacerbating the precarious situation, as they may result in downed trees and power outages, a High Wind Warning is also in place until 8 PM EDT Friday.
The outlook for the night includes increasing clouds with a low around 64 and a 30 percent chance of rain after 3 am, raising concerns for nighttime commuters and suggesting residents prepare for potential disruptions. Furthermore, the weekend does not afford much reprieve, with a 60 percent chance of rain on Saturday, likely showers continuing into the night, and a 50 percent chance of showers on Sunday, impacting weekend plans and necessitating caution and preparedness for ongoing hazardous weather conditions.
Citizens are urged to stay informed and cautious, as excessive runoff may flood rivers, creeks, streams, and other low-lying and flood-prone locations. Strong winds are forecast, and the highest winds are expected across the higher elevations. The lower elevations of the Tennessee Valley will likely experience some high winds Friday morning, which only makes the situation more strained. With the need for vigilance sky-high, casualties of roads and waterways could prove treacherous, if not insidious.
