Summary: A significant downburst wind event occurred west and
southwest of Dalhart, TX on Sunday evening. The downburst was
associated with the rear flank downdraft of a supercell
thunderstorm. Damage from the downburst was initially observed
at the Twisted Elms Golf Course where several trees were
uprooted and many large branches were downed, including some
onto power lines. Damage at the golf course was estimated to
be caused by winds around 75 to 85 mph. The damage continued
to the southeast where several power poles were blown down.
Severe straight line wind damage peaked at the airport where a
74 mph wind was observed by NWS ASOS equipment before the
equipment was damaged by flying debris.  The debris was from
multiple airport hangars that were completely destroyed. Debris
from the hangars was found up to a half mile away. Several
small planes and a pop-up camper were flipped and thrown up to
50 yards. Damage at the airport was estimated to be from 100 to
110 mph winds, which is the equivalent of a high end EF-1

The information in this statement is preliminary and subject to
change pending final review of the event and publication in
NWS storm data.
