Overview
Remnants of Tropical Storm Fred moved north from the Gulf Coast states into the Central Appalachians, Aug 17th-18th. Our area was in a good environment conducive for brief tornadoes, with high shear in place. In addition, a south to southeast flow of high tropical moisture allowed for 2 to 6+ inches of rain to fall over portions of our area, especially in the North Carolina mountains. |
