...NWS DAMAGE SURVEY FOR AUGUST 16, 2018 MICROBURST TENT COLLAPSE...

A thunderstorm formed along the Jefferson/Blount county line, near
the town of Warrior, during the early evening of August 16th, 2018.
This storm moved northward as it reached peak intensity, and
produced an area of microburst winds that aided in the complete
collapse of a large tent at Traditions Park in Hayden/extreme
southwestern Blount County around 7:25 PM. The only other damage
observed in the area was a few small limbs that were downed.

The tent's sidewalls/curtains were rolled up during the event,
likely enhancing the uplift of the structure. Several anchoring
plates were tugged upward from the ground, and there were multiple
tears along portions of metal support beams and joints from stress
on the structure.

Based on the large surface area of the tent, the absence of
significant damage immediately adjacent to the tent, and eye witness
accounts, winds during the storm were estimated to be sub-severe, in
the neighborhood of 40 MPH.

There were a total of 12 injuries that resulted from the tent
collapse; 6 required transport, and a total of 3 were classified as
having serious injuries. There were no fatalities.

Note: The information in this statement is preliminary and subject
to change pending final review of the event and publication in NWS
Storm Data.
