…NWS DAMAGE SURVEY FOR 08/28/20 TORNADO EVENT…

.OVERVIEW…

On the afternoon of Aug 28 2020, Tropical Depression Laura
and its remnants moved eastward across the Tennessee and Ohio Valleys
with a trailing surface boundary across portions of the Deep South.
An abundance of tropical moisture coincided with areas of diurnal
heating to promote an unstable atmosphere which also interacted with
areas of favorable low-level and deep-layer wind shear. As a result,
an environment favorable for the development of strong to severe
thunderstorms established across a good portion of the Mid to Deep
South, including Central Alabama. Strong to severe thunderstorms
developed in the vicinity of southern Tennessee and northern
Mississippi which tracked generally eastward during the mid
afternoon, impacting various areas of northwest Central Alabama.
Damaging straight-line winds produced several areas of tree damage as
a line of thunderstorms moved across these areas. Additionally, two
low-topped supercell thunderstorms moved ahead of this line and
generally east-northeastward into Winston County in the late
afternoon. These rotating thunderstorms were able to re-intensify
and went on to produce two tornadoes, both of EF-1 strength, with the
first near the Grayson and Moreland area, and the second in the
Double Springs area of north and central Winston County.

The tornado developed in a wooded, uninhabited area east of County

where it caused minor timber damage. The tornado caused minor damage
to the roof of a chicken house just off of County Road 415. The
tornado continued northeast where it approached Highway 33 west of
Moreland. The tornado caused notable timber damage as it crossed
Highway 33 then it continues northeast. The tornado moved across
County Road 3163 where it removed sheathing from under a
manufactured home, destroyed a small outbuilding, and removed
portions of siding and sheathing from a manufactured home. The
tornado then crossed County Road 63 or Cheatam Road where it removed
a portion of the roof from a manufactured home, damaged two garage
doors, and blew out a window of a outdoor storage building. A small
portion of this structure suffered some minor exterior wall
relocation from the slab but it was found that the wall was anchored
by nailing to the concrete slab. The tornado continued northeast
before dissipating in wooded, uninhabited terrain near Collier Creek.
