Brief Description: Exactly an hour after producing the first severe weather in the upstate, the supercell produced its strongest tornado in South Carolina. A high F1/low F2 tornado struck Union. Property damage resulting from the tornado's winds was estimated about $500,000. More hail damage is likely as the hail accumulated to great depths very quickly and near the tornado track was quite large. Winds were estimated from 60 to 90 mph in downtown sections where plate glass windows were blown out. There was also considerable damage to trees and power lines along with damage from the wind-driven hail. Nearer the tornado track damage was more severe with large trees crushing some homes. Mobile homes were damaged or destroyed, and a couple of houses lost roofs from the wind. The large hail quickly clogged storm drains and an estimated 2 to 3 inches of rain fell causing $50,000 in water damage to equipment in the hospital. Highest winds from south of Union to near Monarch were estimated at 115 mph in a small area. Two people were slighlty injured when a falling tree crushed their car. | |||||||||||

Brief Description: EVENT NARRATIVE: A National Weather Service Storm Survey Team confirmed an EF2 tornado with winds estimated to 130 mph. The tornado first touched down in a stand of pine trees, snapping approximately 30 of them several feet off the ground. The largest of the snapped trees was 12 inches in diameter. The tornado then moved east into a cluster of homes and mobile homes along East 7 Pines Street. One mobile home was blown 20 yards off its frame and was completely destroyed. The debris was blown into another single wide mobile home which was subsequently destroyed. A large pecan tree was uprooted before the tornado lifted off the ground. The damage was rated EF1 with winds to 100 mph. The second touchdown occurred a few hundred yards to the east. The tornado moved over a stand of trees and descended practically on top of a two story single family residence located on East 7 Pines Street. This dwelling was blown off its foundation and flipped over onto two automobiles and in the process was completely destroyed. Three people were in the home at the time. They took shelter in an interior hallway moments before the tornado struck. They were transported to the hospital, treated for minor injuries and released. A Ford Ranger Pickup was lifted and dropped approximately 50 yards away. A horse trailer was lifted and dropped 100 yards away. A large wood framed workshop and horse barn were also destroyed. The tornado moved east approximately two tenths of a mile and damaged or uprooted several trees as it lifted. The damage was rated EF2 with winds to 130 mph. EPISODE NARRATIVE: A thunderstorm developed along a surface boundary during the evening. The thunderstorm developed supercell characteristics soon after moving into Darlington County and spawned several tornadoes over its lifetime. | |||||||||||
