| 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. | |||||||||||
