End Location:           2 NNW Hammondville / DeKalb County / AL

End Lat/Lon:            34.5998 / -85.6497


Survey Summary:

The tornado touched down on Hwy 71 in Jackson County, snapping

hard and softwood trees to begin its path. The tornado continued

between County Road 425 and 322, producing minor damage to the

roof of a small farm building. The tornado then overturned a

camper and injured two people downstream along County Road 422.

Also at this location, a well-built home was partially destroyed.

A mobile home was moved off its foundation here as well, with a

third of the roof of a hay barn and a horse trailer destroyed.

Projectiles were found in the field across the street from this

home, with 2x4s impaled a foot to 18" in the ground at this

location. Further south and east along State Road 40, large 100+

year old oak trees that were 4-5 foot in diameter were blown down

onto a house, collapsing two exterior walls. Windows were sucked

out at this location as well prior to the trees falling when the

tornado passed just north of the house. Up the street, a well-

built home sustained major damage when the tornado ripped the

garage off of the house and sheared it to the north and east into

the rest of the dwelling. It was at this location that the highest

wind speed was rated for this tornado, 135mph, which is the top

windspeed for an EF-2 tornado. Had anchor bolts been found in the

foundation anchoring of the walls (in lieu of the nails that were

found attaching the walls to the foundation), the tornado would

have been upgraded to an EF-3 tornado. What was left of the house

was in relatively good condition, all things considered, and it

was noted that the attic framing was anchored with strongties, and

so the roof remained intact over a good portion of the house

otherwise. At this point, the tornado was likely at its widest

point, measuring 1.13 miles wide.


NWS representatives returned to the track the following day to access

several roadways that were completely blocked from widespread fallen trees

south of State Road 40. Surveyors found damage indicators and degrees of

damage consistent with EF3 (140mph) tornado damage. The tornado was the

strongest at this point along the path. Along County Road 125, a well built

shop building was completely destroyed. The metal building structure was

well-anchored with H-beams anchored with large bolts and plates at the

bases to the foundation. The bolts were snapped and severely bent, along

with the plates. On one corner, a large 4-5 foot section of the foundation

was ripped off the ground and strewn about 10 feet away with the column

anchoring still intact. More shocking was the 20,000 pound 18-wheeler cab

that was tossed more than 150 yards into the field across CR 125. Other

nearby semi-trailers that were parked on the property were strewn in the

same direction as well, though most only were shifted 50-100 feet.


The tornado continued snapping and uprooting softwood trees over the

relatively rural landscape along Melton Drive and Elliot Road. It was at

this location where the road was impassable due to numerous trees covering

the roadway, and it was actively being removed during our survey. Further

east/southeast, the tornado moved across the intersection of

Culver/Keith/Lacey Roads, snapping and uprooting more softwood trees. The

tornado crossed State Road 40, peeling back tin on several chicken houses

between SR40 and Valley Road, causing the structural integrity of one of

the houses to be compromised. Additional softwood trees were uprooted and

snapped near the intersection of County Road 714 and 120 along State Road

40 as well, with the loss of several roof panels to a shed structure at a

house located here.


Continuing on toward the latter part of the tornado track, a large oak tree

fell onto a house on CR665 and 670. The tornado skipped along uprooting and

snapping more hard and softwood trees between this location and the

terminal point on Hwy 117 on the cusp of Hammondville, mainly in rural

Dekalb County. No additional damage points were found beyond Hwy 117 and

Interstate 59.


Thanks to both Jackson and Dekalb County EMA Offices, as well as several

Fire Departments in both counties for the support and aid in completing

these surveys.

End Lat/Lon:            34.7206 / -86.5468


Survey Summary:

An NWS storm survey determined a tornado touched down near Walker

Ave NE. The initial touchdown point was indicated by snapping of

large branches and significant leaf litter. The tornado continued

generally southeast resulting in several large trees uprooted

between Walker Ave NE and Randolph Ave SE. This track continued

southeast just north of Governors Dr SE with several additional

trees both uprooted and snapped. Between Holmes Ave and near Sun

Valley Rd SE appears to be the location where the tornado reached

its peak intensity of EF1 as indicated by the various uprooted

and snapped trees near SE California St and through the Maple

Hill Cemetery. Further along this southeast track, the tornado

weakened slightly as it tracked north of the Medical District

with additional damage of large branches down and leaf litter

observed. While our last damage point is just north of Governors

Dr SE, radar data indicates the tornadic debris signature

continued southeast over Monte Sano. We have requested additional

drone and satellite data to further refine the ending of this

tornado track and supplement this survey. Some tree damage was

noted just south of Governors Dr SE however this was identified

as wind damage from inflow winds into the supercell. Thank you to

Madison County EMA for their assistance during this survey.

End Location:           3 W Gurley / Madison County / AL

End Lat/Lon:            34.7015 / -86.4245


Survey Summary:

An NWS storm survey determined that a tornado touched down just

north of Little Cove Road. Our initial points for the touchdown

were indicated by siding peeled off of a garage and shearing of

limbs off of tree tops. The tornado then tracked generally east

and continued to distribute leaf litter and snap small branches

before beginning to peel some siding on single family homes. The

tornado then intensified and caused partial uplift of roofs on

the eastern side to four houses on Kenhurst Ln SE. The source of

roof failure for these homes came from the eastern portion of the

roof. The tornado was able to lift the roof from overhangs facing

eastward and then further lift additional portions of the roof.

Roof construction appeared primarily via nails and 2x4 with

Simpson Strong Ties noted along the base of the roof. Based on

these points of strongest intensity, the tornado was deemed a low-

end EF2. Roofing material was lofted one block east on Abby Glen

Way, where there was also additional scattered shingle damage. No

additional damage was noted in this neighborhood. Beyond this

neighborhood to the east lies unaccessible rural areas which we

could not survey. Additional satellite data has been requested to

further analyze the extent of this tornado track and further

updates to the end point may be required. Thank you to Madison

County EMA for their assistance during this survey.

Survey Summary:


A tornado touched down on the Tennessee River just east of where the Elk

River meets the Tennessee River and proceeded to move inland at the

Brigadoon neighborhood. Public photos and videos confirm the tornado

was over water before it moved on land. It first caused damage at

Inverness Place and this is where the homes with the largest amount of

damage was found. The home that had the greatest damage had all

exterior walls facing the river collapsed, the roof of the main

part of the house completely gone and the two story four car

garage was collapsed with the roof also gone. The front of the

house and interior rooms remained in tact. This damage is

correlated with low end EF3 damage. Homes nearby had substantial

roof damage, damaged vehicles, and other various exterior damage.

Numerous large trees throughout the neighborhood were uprooted or

snapped. Moving further into the subdivision, there was roof and

exterior home damage to a lesser extent, fences knocked over by

other debris and broken windows. The tornado lifted in a field

outside of the subdivision.

Survey Summary:

A National Weather Service Huntsville, AL and Lincoln Co. EMA

damage assessment team determined the damage in southwest Lincoln

Co. was consistent with an EF-1 tornado with max winds of

105 mph.


Damage indicators across the tornado path were mostly a

combination of hardwood trees and sporadic, minor structure

damage. The tornado likely touched down near the Blanche Rd area

between Philpot Rd and Cheatham Rd.  Hardwood numerous trees were

observed to be uprooted or trunks snapped with one tree on a

house. The tornado continued across Randolph Hill Rd then caused

more hardwood tree damage across Sanders Rd. The tornado then

followed Dry Creek, south of Poorhouse Rd, where numerous

hardwood trees were snapped through Clay Jones Rd. More

significant damage, including minor roof damage to a single-

family house and more dense areas of tree snaps, occurred east of

Clay Jones Rd. This is the location where the max winds were

recorded by the survey team. The tornado likely lifted east of

this residence in a valley west of Drennon Rd.

Survey Summary:

A second track was found on the Henagar survey, and this tornado

was associated with the second supercell that moved across

portions of Jackson and Dekalb Counties toward Brooks Crossroads.

Thankfully, this tornado went south of the EF3 track through

Henagar, and was generally more weak and brief. This tornado

touched down on County Road 122, snapping and uprooting hard and

softwood trees just south of the Jackson/Dekalb County border.

The tornado continued moving to the east/southeast, snapping and

uprooting widespread trees along CR 122, consistent with EF-

1 damage and 107mph winds in Brooks Crossroads. Though there were

numerous softwood trees that were damaged, notably, there were

several large 4-6 foot in diameter oak trees that were likely

100 years or older that were snapped and uprooted. This led to

the slightly higher rating of the tree damage. Any structural

damage along this path was from trees that were felled by the

tornado, with minimal roof loss noted in this location.

A very weak tornado touched down just east of I 24 at the end of

Mayo Rd in a wooded area.  There was evidence of topping and

twisting of a few trees. Along Stroudville Rd at Tony Darden Rd,

there were 3 trees down that had been cleaned up by highway

department. Witnesses said they saw a much great funnel aloft and

only one small part was touching the trees. When the tornado got to

Highway 256 and Ridge Rd it increased in speed and width and turned

south southeastward. A barn had panels and sheeting torn off and 2

trees were uprooted off 256. Along Ridge road, 3 homes had shingle

and roofing material loss, along with gutter and soffit damage. One

home had 14 trees snapped or uprooted, and one fell on their home.

Along Ridge Rd, drone photography showed dozens and dozens of trees

topped, twisted, uprooted and snapped. An older 20 by 40 barn was

picked up and thrown off to a northeasterly direction, with metal

sheeting thrown well up into the trees and wrapped around the tree.

The tornado took a hard turn back to the east at the very end of the

track. The tornado topped twisted and uprooting trees. It also

damaged metal sheeting on a barn near Ridge Road.

412. More intense damage began to occur on Old Highway 99 and

Blackburn Lane where large sections of roofs were

removed and hundreds of trees were snapped or uprooted. The tornado

reached its maximum strength along Blackburn Rd and Lasea Rd where

large transmission power trusses were collapsed, a house was

destroyed with only small interior walls still standing, and a

mobile home was swept away. The tornado continued northeast damaging

additional homes before crossing I-65 near mile marker 47. More

Bare Bones Forecast

 Well another stormy night has ended, at least the severe weather threat for North Alabama and Southern Middle Tennessee.  The rest of today...
