Survey Summary:
A potent supercell thunderstorm developed over the Dugway Proving
Ground and started producing 90+ mph wind gusts almost
immediately around 455 PM MDT as observed by a weather station on
the range. The storm continued eastward impacting more of the
Dugway Proving Ground where straight-line winds toppled 5000 pound
shipping containers and peeled back the corner of a metal roof of
a fire station. Continuing farther eastward into the Dugway
English Village, numerous trees were uprooted and toppled over.
Here the most signficiant damage was where two large and healthy
hardwood trees next to a residence were snapped at the roots and
toppled over. Immediately adjacent to this residential area is
where two free standing power poles were blown down as well. The
swath of wind continued northeastward into the southern end of the
Skull Valley where additional free standing powerlines were blown
over, and several hardwood trees were snapped or uprooted along
Skull Valley Road and Lincoln Highway. In this area a brief EF-1
tornado was also documented near the intersection of Skull Valley
Road and Lincoln Highway. The storm then moved over the south end
of the Stansbury Mountain Range and into the Rush Valley. Near
Clover and Saint John, Rocky Mountain Power reported crews
replaced up to 20 power poles. The survey team documented numerous
new poles in this area as well as homes and outbuildings with
shingles uplifted or removed. Beyond this point no significant
additional thunderstorm wind damage was found, bringing an end to
the roughly 50 mile continuous swath of of estimated 70-100 mph
winds, with a peak observed wind gust of 93 mph.
