...Summary...
The National Weather Service in Baltimore MD/Washington DC has
confirmed through storm survey and radar analysis the touchdown
of a brief, EF-0 tornado near Berryville in Clarke County Virginia
on May 30, 2017.

Damage began near the intersection of Trapp Hill Road and Harry
Byrd Highway (Route 7), with an oak tree uprooted, falling to the
east along a driveway leading to an estate home on Trapp Hill
Road.

This area has hilly terrain, and it appears that the tornado
skipped a few valleys before doing more damage in the 1000 block
of Trapp Hill Road. At a residence in the 1000 block of Trapp Hill
Road, numerous large branches were down, along with uprooted
hardwood trees. The protective coverings of a wood pile was
strewn towards the south, whereas leave splatter at the residence
was observed on both the northwest and southwest portion of the
structure. Finally, one 18-inch diameter pine tree was snapped at
about 30 feet off the surface, and with the snapped portion of
the tree falling to the west. The magnitude and chaotic nature of
tree damage in this localized area is consistent with tornadic
damage at the EF-0 scale, with estimated winds 65 mph.

The KLWX WSR-88D Weather Radar located in Sterling, Virginia,
exhibited a pronounced hook echo in the 0.5 angle reflectivity
products starting at 5:53 PM EDT, and continuing through 6:02 PM
EDT. While hook echoes in of themselves do not constitute proof of
a tornado, it does provide corroborating evidence that is
consistent with the damage path.

The residents of the impacted household were subscribed to the
Clarke County Citizen Alert System, and were notified via
telephone and text message of the Tornado Warning that was issued
in advance of this storm. This provided them several minutes to
move to the basement of their home, decreasing their risk of
injury due to the tornado. The National Weather Service
Baltimore/Washington Weather Forecast Office encourages citizens
throughout the area to take advantage of their county`s emergency
notification services.

The National Weather Service would like to thank the residents
who reported the damage and helped survey the area; the Clarke
County Department of Fire, EMS, Emergency Management; and the
Virginia Department of Emergency Management for coordination.
