...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 
Road 195 and moved northeast, crossing County Road 6 near Sandy Creek
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.
