Survey: A strong squall line with an embedded supercell moved
from southeast McCurtain County in Oklahoma through southern
Little River County, AR and into western Hempstead County, AR late
Friday night with estimated wind speeds around 70-90 mph. While
our survey was only conducted in Little River County, based off
other non-survey reports, we believe that the swath of damage
extended upstream into McCurtain County, OK and downstream into
western Hempstead County just past Fulton, AR with a total length
around 40-60 miles. In the midst of this swath of wind damage, our
survey did find a short embedded EF-1 tornado approximately 5
miles SW of Ashdown. With the exception of the weak tornado, most
of the damage consisted of trees being uprooted or snapped in an
east to southeast direction. There was also some occasional
structural damage that mainly consisted of roofing material or
shingles on homes and out buildings. In addition, there were also
a few other structures that were considerably damaged by uprooted
trees.

A special thanks goes out to our Emergency Management partners in
Little River, Hempstead, and Miller counties for their help and
assistance with the survey process.

Summary: A brief EF-1 tornado crossed over Little River 21 and the
intersection of Little River 15 and Little River 713 doing
concentrated convergent tree damage in the midst of much wider
straight line wind damage throughout the southern portion of
Little River county. Damage to structures in the tornado path was
very minimal. It is possible that the tornado extends farther than
our survey indicates, however, the actual survey length was
limited by road access.

A special thanks goes out to our Emergency Management partners in
Little River County for their help and assistance with the survey process.

the following categories.
