In addition to the rain, strong winds are forecast. The highest winds are expected across the higher elevations of the east TN, southwest VA, southwest NC mountains, and Cumberland Plateau.

Flood waters will be receding and may still pose a threat before streams retreat back within their banks. .SPOTTER INFORMATION STATEMENT... Reports of wind damage or flooding is very appreciated.
