 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.

 Brief Description: EVENT NARRATIVE: The tornado damage path began near Farmers Academy Rd, about 0.5 mile south of highway 106. The tornado crossed Red Hill School Rd, where some outbuildings were destroyed and a couple of mobile homes received minor roof damage. As the tornado continued northeast, some frame homes on highway 106 received minor roof damage. The most significant damage occurred on Crumps Bridge Rd, where one large chicken house was completely destroyed, and several others received major damage. The tornado continued to move northeast, uprooting or snapping off numerous trees as it crossed highway 145 and Greater Hope Rd. From there, the tornado began to move in a more east/northeast direction, continuing to blow down trees as it moved roughly parallel to North Clarks Creek Rd. As the tornado crossed Hulsey Rd, roofs were blown off the wood frame addition to a mobile home and a barn. After the tornado crossed highway 17 and Pleasant Hill Circle, it continued to turn more to the right, traveling due east near the to Wilson Rd, where a mobile home was moved off its foundation, and the steel siding and some roofing material was blown off a building. The tornado continued to travel east, or even east/southeast, before lifting in the Gerrard Rd area. EPISODE NARRATIVE: Supercell thunderstorms moved into extreme northeast Georgia in the early evening hours. Tornadoes were spawned by the supercells. There was also quite a bit of large hail and straight-line wind damage.

 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.
