 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.

The most significant damage was observed in the Catawba Heights/ Belmont area, near I-85, where much of the metal roof was peeled from a large wharehouse, causing 7 million dollars in damage. Another industrial business in this area lost most of its roof. EPISODE NARRATIVE: A mini-supercell thunderstorms produced a tornado with a nearly 20 mile path through the Gastonia and Charlotte metro areas during the early morning hours of May 9th.

 Brief Description: Tornado began near Santuc as a large multi-vortex F3 tornado. Spotters engaged the storm almost immediately and followed it as it curved north to northwest through the County. The storm had intermittent ground contact of about 30 to 40 percent but there was not a great deal of separation between areas of damage. The path width gradually diminished to about 50 yards from 0.75 mile initially, and the storm intensity gradually weakened to F2 and then to F1 at Pauline. The tornado crossed into Spartanburg County near Pacolet Mills at 1545EST. A well constructed home near Santuc was destroyed, a stationary vehicle was thrown aout 150 yds, and other homes and structures received severe damage along its path.
