Survey Summary: Data from ground surveys in coordination with
Garrett County Department of Emergency Management and the National
Weather Service in Sterling VA, as well as radar data from the
WSR-88D in Pittsburgh PA and Sterling VA confirmed that a tornado of
EF-1 intensity occurred in Asher Glade shortly before 8 PM on
Saturday, May 11.

The first damage was noted just east of the West Virginia state
line at approximately 7:55 PM near the intersection of Glade Road
and Squire Fike Road. Dozens of trees were snapped and uprooted in
a relatively narrow path (about 75 yards wide) in a convergent
manner, indicating that the counter-clockwise rotation of the
tornado was on the ground.

The tornado continued on a path east-southeast across MD-42
Friendsville Road to just east of the intersection of Buffalo
Run Road and Myers Road. In this area, dozens of trees were also
snapped and uprooted in a convergent manner. Radar data indicated
rotation as well as a tornadic debris signature along this path.

This first tornado lifted with no additional tornadic damage (and no
tornado debris signature on radar) noted for several more minutes to
the east-southeast of this location, until a second tornado developed
near Friendsville and Accident.

The National Weather Service would like to extend appreciation to
Garrett County Department of Emergency Management for their
assistance in conducting these surveys.

.Tornado #2...

Rating:                 EF-1

Path Width /maximum/:   75 yards
Fatalities:             0
Injuries:               0

Start Date:             May 11 2024
Start Time:             8:09 PM EDT
Start Location:         Friendsville, Garrett County MD
Start Lat/Lon:          39.6647 / -79.3547

End Date:               May 11 2024

End Location:           Accident, Garrett County MD
End Lat/Lon:            39.6370 / -79.3086

Survey Summary: Data from ground surveys in coordination with
Garrett County Department of Emergency Management and the National
Weather Service in Sterling VA, as well as radar data from the
WSR-88D in Pittsburgh PA and Sterling VA confirmed that a tornado of
EF-1 intensity occurred between Friendsville and Accident shortly
after 8 PM on Saturday, May 11.

The first damage was noted near the south end of Bearfoot Road, and
then southeast along Bear Creek Road. Hundreds of healthy softwood
and hardwood trees were snapped and uprooted in the 3500 and 3600
blocks of Bear Creek Road, with several trees falling on or very
close to a couple of houses and trailers. At least one tree fell
onto a vehicle. Several homes had minor shingle and siding damage
from the force of the wind independent from falling trees. One home 
had a garage door bowed out 8 inches from the force of the wind.

The tornado lifted briefly after passing Everly Road, then touched
down again for a moment as it crossed Pud Miller Road east of
US-219 Garrett Highway. In this area, dozens of trees were also
snapped and uprooted in a convergent manner. Radar data indicated
rotation as well as a tornadic debris signature along this path.

Several scattered instances of wind damage were noted to the
southeast of this location, but the damage was less concentrated
and unidirectional with trees falling in the direction of the
parent storm motion. Also, the tornadic debris signature on
radar ceased once the storm approached and moved through Bittinger,
Fairview, and Westernport.

The National Weather Service would like to extend appreciation to
Garrett County Department of Emergency Management for their
assistance in conducting these surveys.
