Summary:
The Horton Tornado in Southern Marshall County was associated with
the long lived parent supercell that migrated eastward from
the AL/MS state line. The damage assessment team, consisting of
NWS Huntsville and Marshall County EMA, noted the beginning of the damage
west of Old Oneota Rd and Dixie Dale Rd. Numerous trees were either
snapped or uprooted along and adjacent to Old Oneota Rd, indicative
of 90 mph. More significant damage was noted on the west side of Ole
Oneota Rd were two chicken houses and a barn were destroyed.
The team determined winds to be 112 mph, or a low-end EF-2. The second
set of chicken houses destroyed occured near Oneota Cutoff Rd, however
these were not as heavily as damaged. As the tornado tracked due east toward
Hwy 75 , he most prevelant damage was snapped or uprooted trees. On the west
side of Hwy 75, damage was noted to a weak farm building. Damage was not observed
on the east side of the Hwy or at Albertville Regional Airport. However,
numerous snapped or uprooted trees were observed along White Oak Road and
east toward Whitesville Rd. Structure damage was recorded on Whitesville Rd
to a third set of chicken houses, but the damage was downgraded due to the fact
the doors were open. The tornado was estimated to lift just east of Whitesville
Rd before Walnut St.
