few tornadoes. 

...Rural Fairbank Tornado...

Rating:                 EF2
Estimated Peak Wind:    120 mph
Path Length /statute/:  5.00 miles
Path Width /maximum/:   150 yards
Fatalities:             0
Injuries:               0

Start Date:             08/07/2026

Survey Summary:
A well documented, large spatially, HP supercell low-level
mesocyclone produced an EF2 tornado along its 5 mile path. Most
of the damage was EF1 damage to structures and trees. It is
likely that this tornado had numerous short-lived vortices on the
ground leading to the damage observed.  Towards the end of it's
path.  The tornado snapped a wooden H frame power pole at its
base, and also pulled four other H frames from the ground.  The
damage to the power poles suggests winds at least up to 120 MPH.
