| Brief Description: EVENT NARRATIVE: A tornado damage path extended from northwest Anderson County, into extreme southern Pickens County, affecting the research area on the south side of the Clemson University campus. Damage was limited to downed trees and power lines. Numerous large trees were snapped off on a ridge very close to the Pickens, Anderson County line, where wind speeds were estimated at close to 120 mph, earning the tornado an EF2 rating. EPISODE NARRATIVE: The remnants of Tropical Storm Fay stalled just west of the Appalachians and slowly dissipated. A line of mini-supercells developed southeast of the low, resulting in several tornadoes over the Upstate and Northwest Piedmont of South Carolina during the afternoon hours of the 26th. A small amount of flash flooding also occurred, though the flooding was much worse in North Carolina. | |||||||||||
