...SUMMARY OF STORM SURVEYS FROM JUNE 10, 2020 STORMS...

.BEAVER COUNTY TORNADO

Start Location...Ohioville in Beaver County Pennsylvania
End Location...Daugherty Township in Beaver County Pennsylvania 
Date...June 10 2020 
Estimated Time...931 pm EDT 
Maximum EF-Scale Rating...EF2
Estimated Maximum Wind Speed...120 mph
Maximum Path Width...790 yards
Path Length...10 miles (intermittent)
Beginning Lat/Lon...40.68N / -80.44W
Ending Lat/Lon...40.76N / -80.29W 
* Fatalities...0
* Injuries...0

...Summary...
The National Weather Service in Pittsburgh confirmed an EF2
tornado on June 10 2020. The damage started in the vicinity of 
Tuscarawas road then moved east north to where five power poles 
were snapped near the Shop n Save plaza. This is where the 
strongest damage was observed of the entire track. The remainder
of the track, hardwood and softwood trees were used to estimate
wind speed. 

The tornado continued northeast and caused uprooted hardwood and
softwood trees through Bradys Run Park. A lull in damage was
observed given limited access around Interstate 376 south of the 
Brighton exit. Damage picked up again in Daughtery township where 
at least 40 to 50 hardwood trees were snapped or uprooted. One 
tree that was uprooted left a six foot crater in the ground. The 
last damage was recorded just northeast of Klein Road. The path 
length may need to be adjusted pending further information from 
the Molly road area of North Sewickley Township. 

The last tornado to hit Beaver county was July 10 2017. This is
the strongest tornado to impact Beaver county since the May 31
1985 outbreak where a F4 tornado was recorded.  

We would like to say thanks to Beaver county Emergency Services
and the Daughtery Township Emergency Officials for their
assistancewith the survey.


.LEETONIA/WASHINGTONVILLE TORNADO...

Start Location...Leetonia in Columbiana County, OH
End Location...Washingtonville in Columbiana County, OH
Date...June 10, 2020
Estimated Time...924-927pm
Maximum EF-Scale Rating...EF0
Estimated Maximum Wind Speed...70-75 mph
Maximum Path Width...75 yards
Path Length...0.8 miles
Beginning Lat/Lon...40.891N / 80.768W
Ending Lat/Lon...40.900N / 80.760W
* Fatalities...0
* Injuries...0

...Summary...
A brief tornado was confirmed in northern Columbiana County 
following a survey of damage in the Leetonia/Washingtonville area.
Damage began just north of the Leetonia High School and was most
concentrated along Leetonia Road, where numerous trees were
snapped or uprooted. Minor fascia damage also was noted in this
area.

The circulation then weakened as it progressed northeast, with
tree damage continuing to the county line, where debris evidence 
seemed to end abruptly. NWS Pittsburgh observed no evidence of 
wind damage continuing into Mahoning County, which is coincident
with a weakening trend in the radar-depicted circulation.

Damage earlier in the circulation's track across Salem Township was
sporadic and did not prove to be conclusively tornadic.

At its peak, tree damage was consistent with wind speeds of 70-75
mph near the beginning of the swath along Leetonia Road. The
tornado was very narrow and brief, and additional wind damage just
south and east of the tornado likely was caused by enhanced
straight-line wind associated with the tornado's parent mesovortex
and rear-inflow surge.

Much gratitude is extended to the Columbiana County EMA and local
fire chiefs for their guidance and assistance during this storm
damage survey.


.HANOVERTON AREA TORNADO

Start Location...2 SE Hanoverton in Columbiana County, OH
End Location...4 ENE Hanoverton in Columbiana County, OH
Date...June 10, 2020
Estimated Time...911-914pm EDT
Maximum EF-Scale Rating...EF0
Estimated Maximum Wind Speed...75 mph 
Maximum Path Width...150 yards 
Path Length...2.5 miles 
Beginning Lat/Lon...40.744N / 80.912W
Ending Lat/Lon...40.768N / 80.878W
* Fatalities...0
* Injuries...0

...Summary...
Damage along this discontinuous path began in relatively open
terrain southeast of Hanoverton and continued to near Richey
School Road and Route 30 northeast of Hanoverton. The most
concentrated area of damage encountered was along Lindesmith Road,
where a farmstead was impacted by the tornadic wind. In and near
this location, several trees were snapped or uprooted, and several
additional large limbs had been snapped. Also here, sheet metal
roofing from a barn was removed, and two 3000 lb hay wagons were
relocated upwind of their prior location. Damage in this vicinity 
likely was a combination of tornadic and non-tornadic wind. Toward
the end of its path, a home showed damage to its fascia. No
evidence of consistent damage was discovered thereafter.

Much gratitude is extended to the Columbiana County EMA and local
fire chiefs for their guidance and assistance during this storm
damage survey.


.ROGERS-EAST PALESTINE-SNPJ DAMAGE

Location...Rogers, OH in Columbiana County to near S.N.P.J in Lawrence County, PA
Date...June 10, 2020
Estimated Time...929-940 PM
Estimated Maximum Wind Speed...80 mph 
Maximum Path Width...0.6 miles 
Path Length...Roughly 11 miles 
Beginning Lat/Lon...40.796N / 80.595W 
Ending Lat/Lon...40.923N / 80.470W
* Fatalities...0
* Injuries...0

...Summary...
This path was evaluated owing to the presence of a radar-depicted
mesovortex track. Damage along this extensive track was the most
considerable examined today, with abundant tree destruction in the
form of uprooted or snapped hardwood trunks, widespread snapped
large limbs and occasional fascia and shingle damage to single-
family residences. A tree was blown onto an occupied vehicle east
of Rogers, OH early in the swath before wind speed appeared to
increase considerably. Elsewhere along the path, several 
outbuildings suffered roofing damage, including a barn in Lawrence
County, where a portion of the roofing structure was removed and 
transported downwind among other local damage. Damage to power
poles along the swath appears tied to trees falling on power
lines.

Damage was concentrated in several areas, including the western
and northern sections of East Palestine, the area near Howell 
Road/Route 14 area and areas adjacent to the Pennsylvania Turnpike
in Little Beaver and North Beaver Townships of Lawrence County,
PA.

Ultimately this damage was deemed to be non-tornadic but of
considerable intensity. The swath generally paralleled the radar-
depicted mesovortex on its southeast flank, but featured 
considerable width and a modestly divergent pattern atypical of
mesovortex tornadoes. Nevertheless, the wind speed along this
swath was of comparable intensity to many tornadoes and over a 
broader area, leading to the widespread damage observed.

At its peak over this roughly 11 mile swath examined, damage was
consistent with speed up to 80 mph at times. A vast majority of
the damage examined was consistent with wind of around 70 mph.

It is entirely probable that severe wind continued northeast of
the swath evaluated today, but a coherent swath was no longer
noted, and the radar-depicted mesovortex dissipated hereafter.

Much gratitude is extended to the Columbiana County EMA and local
fire chiefs for their guidance and assistance during this storm 
damage survey.


EF Scale: The Enhanced Fujita Scale classifies tornadoes into the
