EF0 tornado, Jefferson County, Pennsylvania, July 18, 2026
This EF0 tornado ran 0.2 miles across Jefferson County on July 18, 2026, touching down at 4:44 PM EDT and reaching 75 yards wide. It killed nobody.
Preliminary. This is NWS PBZ's damage survey, filed in the Damage Assessment Toolkit. The rating, the path and the casualties are the survey's and can change while it is revised. The Storm Prediction Center compiles the official record of 2026 from these surveys and publishes it in the spring of 2027; this page moves to that tornado's permanent address when it does.
The rating scale
Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
EF065 to 85 mphthis tornado
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mph
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
EF2111 to 135 mph
Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.
EF3136 to 165 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
EF5over 200 mph
Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.
Unrated
The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the survey found
NWS has confirmed a second tornado of EF0 intensity occurred from
the same storm as it crossed near Punxsutawney on July 18, 2026.
The storm moved into areas just north of Punxsutawney and caused
damage to a BMX track. The track was just off to the east of
Scotland Ave. Here, there were numerous instances of uprooted
small trees. The damage to the trees were indicative of wind gusts
up to 80 mph. The tornado curved northeasterly along Graffius
Ave, consistent with a rapid occlusion of the circulation at the
end of its brief existence.
NWS Pittsburgh appreciates the photo and video imagery provided
by Jefferson County EMA and Punxsutawney Fire Department.

The damage survey
5 damage points were recorded along this path by NWS PBZ, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 82 mph.

What this means
Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.
