Damaging Wind Associated with Funnel Cloud Passing Over Coweta County, Georgia
May 7, 2003
by Matt Sena |
A severe thunderstorm exhibiting a
strong rotational signature on the WFO Peachtree City WSR-88D
radar moved across eastern Coweta County on the evening of
Wednesday May 7, 2003, from approximately 7:30 through 8:00 PM EDT.
After the storm moved through, reports of damage were received.
On Thursday May 8, 2003, with the assistance of the Civil Air Patrol,
a short aerial survey was conducted. All significant damage was found
in the Lower Fayetteville Road and SummerGrove Subdivision area.
The first signs of wind damage found from the air were in the
SummerGrove Subdivision east of Interstate 85 and south of Lower
Fayetteville road. The damage in the western end of the subdivision
was confined to random trees blown over in yards in the subdivision.
The first signs of large, contiguous areas of trees blown down were
found along the northern edge of the subdivision along Lower Fayetteville
road at the intersection with Sullivan road. These
trees were blown over in a uniform direction pointing from the
southwest to the northeast. A short distance to the east, on
the north side of Lower Fayetteville road, just past the
intersection with Lora Smith road, a large, triangular
area of trees was blown over. All of these trees were
laying in a southwest to northeast direction.
Another widespread area of trees blown was over, with all
of these trees also laying in a southwest to northeast
direction, was located on the north of side of Lower
Fayetteville road on the east shore of Chandler's Lake.
Only random, single or small clusters of
damage to trees was witnessed east of Highway 154 along Lower
Fayetteville road, and no damage was seen east of Fisher road.
Scattered evidence of minor damage to houses
was also noted along this entire path. This damage was mostly
observed to be in the form of peeled shingles and other light
to moderate damage to roofs and siding, and a few instances of
trees falling and striking a portion of nearby houses.
Based on this pattern of damage it appears that all
damage seen was due to strong, straight-line winds,
and not due to tornadic winds. The location of the
damage in relation to the strong rotational signature
seen in the velocity images from the Peachtree City radar
indicate that it is likely that strong winds flowing into
the strongly rotating thunderstorm, and not downburst winds were responsible.
