Survey Summary:
This strong tornado produced by a long-lived supercell 
thunderstorm first touched down along Highway 126 in rural 
southeast Caldwell Parish, just southeast of the Holum community.
Interestingly, the most intense damage of the tornado occurred 
here as two residences were essentially destroyed. One residence 
was a one or two family residence which had its roof and most 
walls removed, including many interior walls collapsed. The one
human injury of this tornado occurred here, but fortunately this
was a non-critical injury. This damage was rated at a strong EF2. 
Another home, a single wide mobile home, was destroyed and this 
damage warranted a rating of a weak EF2. In addition, many barns 
and/or outbuildings were destroyed in this general location and 
at least several livestock were killed. The peak 140 mph EF3 
rating of this tornado was achieved at this location, due to 
observed tree debarking around the one or two family residence. 
Also of interest was significant observed ground scouring near 
where livestock were killed. This ground scouring is usually a 
trait associated with very intense tornado vortices, but it is 
not an official damage indicator we can use to rate tornadoes 
at this time. 

From this location the tornado continued on roughly 3.5 miles
east northeast before crossing Wyant Road near the Twelve Mile
Post Road intersection. The survey team did not have road access 
in this 3.5 mile span before this road, but used available drone 
footage to confirm significant swaths of tree damage in this gap. 
Only tree damage was observed along Wyant Road, but the high level 
of tree snapping was enough to confirm EF2 strength here. From 
here the tornado continued on down Wyant Road, which had turned 
northeast to criss cross the tornado's path through hillier 
terrain. The tornado damage showed a tendency for the tornado to 
narrow and weaken at times through the terrain, but it did 
continue without lifting until reaching the Ouachita River. 
Along the southwestern bank of the river there were two homes 
which recieved heavy damage and several outbuildings which were 
totally destroyed with debris thrown into the river. The 
tornado crossed the river and did significant tree damage along
Lee Lane. From there the tornado continued east northeast while
gradually narrowing and weaking, crossing Highway 559. Based on
downed trees and additional information from satellite, the track 
was extended slightly farther east after crossing Parish Road 6625.

A special thanks goes out to drone teams from the Caldwell 
Parish and State of Louisiana Law Enforcement Offices and to
the Caldwell Parish OHSEP for assistance in locating the damage.
