... NWS damage survey for July 21, 2018 tornado event...

A rare summertime Alabama tornado occurred during the late-afternoon
hours of July 21, 2018 in central Lee County. A southeastward-moving
thunderstorm fed off a primed atmosphere, characterized by strong
instability and wind shear, with a few surface boundaries across
east Alabama. The storm interacted with and ingested an outflow
boundary, aiding in the development of a tornado.

.Opelika-Beauregard tornado (lee county)...

Rating: EF-0
estimated peak wind: 85 mph
path length (statute): 6.3 miles
path width (maximum): 500 yards
fatalities: 0
injuries: 0

Start date: June 21, 2018
start time: 543 PM CDT
start location: 1 se Opelika / Lee / al
start lat/lon: 32.6488/-85.3701

End date: June 21, 2018
end time: 601 PM CDT
end location: 2 NNE Beauregard / Lee / al
end lat/lon: 32.5663/-85.3609

National Weather Service meteorologists surveyed damage in central
Lee County and determined that it was consistent with an EF-0
tornado. The tornado formed near south 3rd street on the east side
of Opelika, where light tree damage was noted. As the tornado moved
southeast, there was an increased number of uprooted trees, though
no structural damage to the surrounding homes. As the tornado neared
I-85, some shingles were blown off various units of an apartment
complex. The density and extent of vegetative damage ramped up south
of I-85, near/just north of Chewacla Road where numerous tree were
uprooted with a few snapped trees. A nearby home sustained damage
from falling branches and a tree, but not from the wind itself. The
tornado then turned more southerly, producing additional swaths of
tree damage. Again, structures (20-30) suffered damage from fallen
large branches and trees versus the wind itself. A few cars were
crushed by fallen trees. One Camper was rolled onto its side. The
tornado ended along Moores Mill Road.

Ef scale: the Enhanced Fujita scale classifies
tornadoes into the following categories.

EF0... weak... ... 65 to 85 mph
EF1... weak... ... 86 to 110 mph
EF2... strong... .111 to 135 mph
EF3... strong... .136 to 165 mph
EF4... violent... 166 to 200 mph
EF5... violent... >200 mph

the information in this statement is preliminary and subject to
