Survey Summary: 
The mesovortex from the quasi-linear convective storm that
produced the Talbot County tornado intensified as it moved into 
Upson County. A tornado developed just outside of of the southern 
city limits of Thomaston near Gordon School Rd east of Old 
Talbotton Rd, increasing in intensity as it traveled northeast. 
The tornado narrowly missed the densely populated Lincoln Park 
area but did hit Southern Crescent Technical College and Raintree 
Golf and Country Club on US19 with winds of 70 to 85 mph. The 
tornado intensified further after it passed Triune Mill Rd, where 
homes and cars were damaged from falling trees, on a path parallel
to and just south of Yatesville Highway. As it reached Trice 
Cemetery Rd, the tornado broadened to over 2/3rds of mile in 
diameter. An unoccupied mobile home rotated 90 degrees and rolled 
on its side. As the tornado moved into Trinity road it reached 
maximum intensity where a single story home had most of its roof 
blown off and every tree (mostly Loblolly Pine) within a 1/8 mile 
radius was snapped. It was at this point that the KFFC WSR-88D 
radar (about 30 nm NNW of this location) detected a rotation 
velocity of 90kts and tornado debris was detected at an altitude 
of 25,000 ft. The tornado slowly began to weaken as it traveled 
through northeast Upson county and into far southern Lamar County 
crossing US341 before finally lifting near Community House Rd just
east of Leverette Rd.

In total, 159 structures were affected, 38 homes had minor
damage, 20 with major damage and 7 were destroyed.
