...PRELIMINARY FINDINGS OF STORM DAMAGE SURVEY...

A storm damage assessment team from the National Weather Service
dispatched this morning to survey damage from storms that
impacted the region during the late afternoon and evening of
Tuesday, July 11, 2017.

Initial findings from the storm damage survey indicates EF-0
damage along a path from west of Larimore, ND southeast to near
Northwood, ND.

EF-2 damage occurred west of Buxton to near Cummings as the storm
intensified. The storm cycled and reformed as it progressed to
the southeast. Damage in Hillsboro, ND was the result of rear
flank downdraft winds accompanying the main part of the tornado,
which passed a couple of miles northeast of Hillsboro. The winds
that caused the damage in Hillsboro was estimated to be in the 80
to 100 mile per hour range.

A third track was noted in Norman County, MN. The damage that
occurred in the Halstad, Borup and Ulen, MN. areas was a result
of broad scale downburst winds accompanying the tornado, which was
also in the EF-2 range.

This information is considered preliminary. More detailed
information will become available later once the survey has been
completed.
