...Summary...
During the afternoon of August 22, 2019, a series of strong to
severe thunderstorms moved northeast and east through much of
southside VA and north-central NC. Many of the storms produced
spotty wind damage with large tree limbs, and in some instances,
trees being broken or uprooted.

One storm in particular produced a more concentrated area of wind
related damage as a burst of extremely heavy rain and associated
strong and damaging cool outflow slammed into the ground and
spread out in a divergent straight-line wind pattern - also known
as a microburst.

This microburst primarily impacted a three to four block area in
the northwestern part of Danville, and encompassed parts of Wills
Street, Charlotte Avenue, Brook Circle, Shumate Street, and Shady
Lane. In this particular area, tens of trees were broken or felled
by approximately 80-90 mph winds - some of which damaged local
structures, including homes.

Although the damage was not caused by a tornado, it is important
to note that microburst winds can result in damage comparable to
that of a tornado - but with the main distinction being that a
tornado often produces a very narrow extremely damaging path with
trees being felled in markedly differing directions from the
storm path, whereas microburst winds usually result in trees being
felled in nearly the same direction of storm movement - which was
the case in the Danville event. Eye witness accounts also confirm
that the damage was due to a sudden burst of extremely strong
winds from the same direction - with no cloud rotation or funnel
evident.

The NWS wishes to thank the Deputy Emergency Management
Coordinator / Danville Fire Department for their invaluable
documentation and assistance provided to make this summary
possible.

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