Special Weather Statement
Issued: 6:21 PM Aug. 12, 2025 – National Weather Service
...Localized Flash Flooding Possible Through Wednesday across East Tennessee...southwest Virginia...and southwest North Carolina... A stream of tropical moisture will move north from the Gulf into the Tennessee valley and southern Appalachians through Wednesday. Periods of showers and embedded thunderstorms can be expected. Due to the abundant moisture these storms will be capable of producing excessive rainfall rates. If the storms move across the same locations, localized flash flooding is possible. Persons living near streams need stay alert for the potential of rapid water rise and flash flooding. Localized flooding of low lying areas and roadway flooding are possible. Please stay tuned to your NOAA weather radio and favorite radio and TV stations for the latest forecast and possible flash flood warnings or advisories in your area.
