...NWS DAMAGE SURVEY FOR JUNE 22ND, 2017 TORNADO IN WEST JEFFERSON
COUNTY...

.OVERVIEW...

Bands of showers and a few thunderstorms, rotating around the
remnants of Tropical Storm Cindy, produced flooding rainfall and
tornadic activity. One storm produced a tornado of EF-1 intensity in
western Jefferson County. A second storm produced a tornado debris
signature in western Shelby County, of which is scheduled to be
surveyed tomorrow (Saturday, June 24th).

.Tornado #1 Fairfield Tornado (Jefferson County)...

*NOTE: Due to the arrival of thunderstorms, the survey team was not
 able to completely assess the beginning of the tornado track,
 specifically from Interstate 459, north to the Bessemer area. This
 area will be looked at tomorrow (Saturday, June 24th). For now, the
 start of the tornado track is placed in the Brighton area, as an
 early look revealed no damage south of this touchdown point.

Survey Summary: National Weather Service Meteorologists surveyed
storm damage in western Jefferson County, and found that the damage
was consistent with a tornado. There were three separate notable
increases in damage severity and/or density, likely indicating that
the tornadoe`s funnel had a skipping/cycling characteristic as it
swayed from less to more intense.

The tornado touched down along 5th Street North, between Highway 11
and Avenue A, where damage ranged from broken large limbs to
uprooted and snapped trees. The tornado then traveled northeast with
a long swath of damage centered along a track generally between
Interstate 20/59 and Highway 11. Aside from continued uprooting of
trees and downing of limbs, the first notable damage occurred just
west of Western Hills Mall, where there was hefty damage to an
Express Oil Change, Alabama ABC store, and mini strip mall, along Dr.
M.L.K. Boulevard. Damage at this location was likely the result of a
short- lived vortex. Due to the assessment of damage indicators
(affected buildings), degree of damage (extent of damage to
buildings, plus consideration of construction quality and wind entry
points), and surrounding signals, the rating for this tornado has
been reduced from the preliminary rating of EF-2 to an EF-1.

The tornado continued knocking down trees as it moved northeast,
with some trees falling onto homes, resulting in severe
roof/structural damage. Tornadic winds also caused minor to moderate
roof damage ranging from missing shingles to sections of roof and
roof trim damaged, especially in neighborhoods adjacent to Miles
College (to the south and northeast). Given a noticeable increase in
damage density, it`s possible that the tornado briefly intensified
in this area. While there was an obvious increase in the amount of
uprooted trees, there was a large contribution from shallow root
systems and especially saturated soil from several-day`s rain; thus,
given a lack of notable wind-driven damage to homes (which held in
EF-0, characteristic of shingle and roof trim damage), the overall
damage pattern didn`t tip the scale for a small corridor of EF-1
rating.

Next, the tornado neared and crossed Interstate 20/59 where extent
of damage backed off, though some minor structural damage done to
the Tire Tech car bay, and Freeway Honda. Windows were also blown
out of a few cars at Honda dealership. An increase in the number of
uprooted trees was again observed surrounding Tuxedo Park on the
north side of Interstate 20/59, along with roof damage to a few
homes. Tornado damage became very sporadic and increasingly less
significant as the tornado neared Bankhead Highway, dissipating near
the CSX Transportation railways adjacent to Pratt Highway.
