Survey Summary:
NWS Storm Survey found a weak EF-0 tornado associated with a QLCS
near Irvington. The tornado began just south of Old Pascagoula Rd
where a couple large hardwood limbs were snapped and very weak
convergence was noted through this area. A wider swath of
damaging wind likely extended west where small branches were
snapped laying due south. The tornado then crossed I10 where it
produced minor damage to the underskirt to two manufactured
homes. The tornado continued down Mcdonald road where a more
noticeable concentration of hardwood tree damage was noted near
Roush Rd. A few hardwoods were snapped but the trees appear to be
rotted and un-healthy leading to a lower bound estimate more in
line with large branches. Weak convergence was noted in the
damage with a more divergence pattern further west towards the
Walmart Facility where likely 60-75 mph straight line winds
occurred. The tornado was likely discontinuous or intermittent as
it traveled south/southeast towards Half Mile Rd where it
produced minor tree damage in the form of small to medium limbs
being snapped. A farm outbuilding had a section blow out near
Half Mile Rd and Matlock Rd. An opening on the one side of the
building suggests a lower bound estimate for this damage as wind
likely got inside the building unimpeded. The metal from this
building was deposited almost due east of the bar suggesting
convergence along or near Matlock Rd. The tornado likely lifted
near Cornelius Rd and One Mile Rd but not without uprooting a
hardwood tree and couple more large branches being snapped. Light
straight line wind damage was noted further south, but no
convergence was able to be determined.
