.Chattooga/Walker County…

Rating: EF2
Estimated Peak Wind: 120-125 mph
Path Length /statute/: 15.8 miles
Path Width /maximum/: 800 yards
Fatalities: 0
Injuries: 0

Start Date: 04/12/2020
Start Time: 8:15 PM
EST Start Location: 1.8 mils miles NW of Summerville (Chattooga County)
Start Lat/Lon: 34.4990 / -85.3689

End Date: 04/12/2020
End Time: 8:32 PM EST
End Location: 4.2 miles SE of LaFayette GA (Walker County)
End Lat/Lon: 34.6660 / -85.2150

Storm Summary: This tornado originated just north of Summerville in
Chattooga county where several trees were snapped or uprooted around
the Hair Lake Road/Mahan Road intersection. The tornado traveled
northeast, continuing to snap or uproot small to medium-sized trees.
A 10K pound camper was overturned by the tornado near Orchard Hill
Road otherwise structural damage was mainly confined to shingles
and/or siding being pulled off homes. As the tornado continued to
travel toward the town of Pennville over some remote terrain, it
appeared to briefly intensify over Back Penn Road, just west of Hwy
27. A trailer was destroyed and one corner of a barns exterior wall
was heavily damaged. Multiple trees around this property were
uprooted as well. The damage at this point was consistent with an EF-
1 (90-95 MPH winds). Mainly pockets of tree damage and minor
structural (roof) damage was then seen as the tornado moved just
east of Trion, beginning to encounter Taylor Ridge and the Walker
county line.

The tornado crossed the Chattooga/Walker county line nearly
paralleling Halls Valley Road. Trees were down on either side of the
road as the tornado appeared to turn more north, possibly being
affected by the higher terrain/ridge to the east. More significant
tree damage was seen along Ramey Road just before Hwy 151. Evidence
of numerous large trees snapped along with more intense structural
damage along 151 just east of Halls Valleys Road suggested the
tornado intensified to EF-1 quickly. It was also at this time that a
small Tornado Debris Signature (TDS) was seen from KHTX (Hytop AL)
radar. About 1/4 mile up the hill from 151 and Halls Valley Road, a
2-story home was hit hard. The entire second story and roof were
removed with heavy damage to the exterior walls. A jeep was also
tossed more than 150 yards from its original location. An additional
home had a good portion of its roof torn off on one side while the
floor above the garage collapsed on the other side. Windows and
doors were blown out and numerous large pines were snapped about
halfway down. It was in this area between the Hwy 151 and Halls
Valley Road intersection and Beard Drive, the tornado was at its
strongest (EF-2) with max winds between 120-125 MPH. The tornado
then crossed Hwy 151 around Mildreds Way with more snapped/uprooted
trees, then appeared to quickly weaken as it rode the west-side of
Taylors Ridge. Tree damage dropped off and ended near Smith Gap
Road with no other damage seen beyond this point.

northeast crossing Back Valley Road downing several trees on the
Trenton Golf Club property. Along US Highway 11, additional trees
were downed damaging houses before the tornado moved into the city
of Trenton. In Trenton, notable damage occurred along Glenview

Storm Summary: This tornado touched down in west-central Murray
county (GA) along Mitchell Bridge Road, just northwest of the Indian
Trace Golf Course, where several smaller trees were snapped in this
location. Additional damage was seen along a path that crossed Twin
Lakes Road and Hwy 286 where a few trees were snapped or uprooted and
minor roof/siding damage occurred at several homes. The tornado
appeared to briefly strengthen around Ellis Circle where there was more
notable exterior damage to homes along with a higher number of trees
seen uprooted. As the tornado crossed Fullers Chapel Road,
noticeable strengthening occurred. Aerial drone footage indicated a
wide swath of large trees cut down just before Norton Bridge Road.
Then, at least 8 double-wide manufactured homes were completely
destroyed along Deer Park Drive, with several others sustaining some
type of damage. It was here the tornado quickly jumped to EF-2
intensity with max winds around 125 MPH. Continuing north-
northeast, similar significant damage was seen along Ridgeview Lane
and Fieldview Court, where additional (mainly doublewide)
manufactured homes were destroyed. Also, a recently built cell tower
was left crumpled by the intense winds. At this point, the tornado
reached its peak intensity with max winds around 135 MPH (high-end
EF2). The tornado maintained its EF-2 intensity as it crossed over
Zion Church Hill Road, just before Hwy 225. As the strong tornado
crossed 225, a small single-family home was heavily damaged with
just a couple of interior walls left standing. Along Jim Petty Road,
there were 4 large chicken houses one was completely destroyed
with heavy damage to 2 of the other 3. Debris was thrown several
hundred yards away. Estimated winds continued in the 110-120 MPH
range in this area. Heading north along Jim Petty Road near Hawkins
Road, the damage appeared to lessen quickly with just a few trees
down and minor structural (roof) damage to a shed. Very little if
any damage was then seen beyond Baxter Road. The tornado is
believed to have lifted just before Sumac Ridge.

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

    MUCH MORE DAMAGE IN SOUTH WALKER COUNTY AND NORTH CHATTOOGA COUNTY THAN INDICATED. TORNADOES AND HIGH WINDS DESTROYED MORE HOMES AND BUILDINGS THAN RECORDED. FLOODING AFTER TORNADOES RUINED HOMES, BUILDINGS, ROADWAYS.
