		Brief Description: A tornado developed from a fast moving severe thunderstorm that raced north out of eastern Georgia. The F2 tornado destroyed several houses and mobile homes and severely damaged many other homes and businesses. Damage was sustained to the south of the track of the tornado due to strong inflow into the storm. Damage from severe thunderstorm winds in the rear flank downdraft occurred north into Easley. A powerful winter storm brought flooding rain, high winds, and a tornado to the Upstate from the evening of the 7th into the early morning of the 8th. Rainfall between 4 and 7 inches during a 2-day period across the mountains and foothills resulted in significant flooding. Many roads and bridges were covered or washed out. A wash out in Pickens county resulted in one fatality. Thunderstorms raced north through the area adding to the deluge as well as creating or enhancing strong to damaging winds. An F2 tornado touched down near Easley. Meso-scale high winds behind the complex of thunderstorms moved across the northern half of Greenville county and blew down trees and power lines. Severe thunderstorm winds combined with strong gradient winds to down trees and power lines in York county as well.

		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.
