Up to a half a foot of rain and flash flooding are possible early next week across East Tennessee, Southwest North Carolina and Southwest Virginia, the National Weather Service said in a statement Saturday morning.
You can thank Tropical Storm Lee.
Tropical Storm Lee was located just south of Louisiana early Saturday morning and is producing heavy rainfall across the southern Mississippi River Valley.
This system will move slowly north today and Sunday across the central Gulf Coast states.
By Sunday night and into Monday, the remnants of tropical storm Lee and associated tropical moisture will move northeast into the Tennessee Valley and Southern Appalachians, the Weather Service said.
The system will collide with a stationary front over the area to produce heavy rain and thunderstorms. The rain will persist through Wednesday.
Rainfall amounts between 3 to 6 inches are expected with this system, especially across the Plateau, southeast Tennessee and northwest North Carolina. Locally heavier amounts are possible.
The heavy rains could produce extensive flash flooding of area streams, low lying areas, street flooding, and mud slides. There is a great deal of uncertainty of the exact path of this system so please stay tuned to further updates to the forecast, the weather service said.
