Tornado Surveys From Last Night


The National Weather Service in Huntsville has been busy. I especially like how they mention cases where people got the warnings and got to a safe shelter before the tornado hit. 

And even though it's way South of our area, I'm including the survey that the Birmingham office did of the Hale/Perry County tornado because even though it was "only" rated an F-1, two people were seriously injured in a mobile home. A few weeks ago, we had a tornado (rated F-2) in East TN that killed a couple people and injured a couple more in mobile homes. This continues to be our main problem besides people not getting warnings reliably. 

Most of the damage was from straight-line thunderstorm winds though. At one point I read that 200,000 Alabama Power customers had an outage this morning. And I think it usually takes a major hurricane moving inland to pull off a stunt like that. It was a rough night for a lot of people. Getting by with only two injuries is actually a pretty good outcome considering how bad and widespread the weather got. 

8:38 PM - Adding a note here that the Waco tornado did also produce one injury, but I missed it on the first read-through because the survey did not note under what circumstances the injury occurred. Still, three injuries total for an event this bad is a good outcome IMHO.

The tornado touched down near the intersection of Lamar Rd and Frankfort Rd.
The tornado caused immediate and widespread damage in
neighborhoods SW of downtown Tuscumbia. This includes roof damage
to an Elementary school off Glendora Ave. Damage indicators were
mostly a combination of uprooted hard and softwood trees.
Numerous homes had roof damage associated with felled trees. As
the tornado tracked into downtown, power lines and traffic
signals were destroyed. Significant roof damage occurred near 5th
and Main St where a metal roof was completely removed. As the
tornado moved out of the downtown area, numerous trees were again
uprooted along 5th and 6th St. through Commons St. The tornado
lifted east of Commons Street before reaching Kings Ave.

End Location:           6 SE Littleville / Franklin County / AL
End Lat/Lon:            34.5136 / -87.6082

Survey Summary:
An NWS and Franklin County (AL) EMA survey team determined that
an EF-2 tornado caused damage in central Franklin County. 

The tornado quickly formed while embedded within the line of severe
thunderstorms late Saturday night. It touched down just south of
Russellville Rd. and east of Harris Creek. There the tornado blew
out the doors of a large, metal storage shed and lofted an ATV
across the property. The tornado shifted ENE just south of
Russellville Rd. and Hwy 75 where it uprooted numerous hardwood
trees, some of which fell on houses. Residents at this location
received advanced NWS warnings and took refuge in their tornado
shelter before their home was impacted. Several homes also
experienced partial roof loss further east on Russellville Rd.
The tornado shifted north Hwy 24 where the vortex contracted and
strengthened. Among uprooted hardwood trees on one property, the
upper quarter of a large silo collapsed. Further east, numerous
trees were uprooted, some on houses and cars. Near Hwy 78 and Hwy
83 junction, a manufactured home was impacted with roof and
siding damage. The resident was thankful for the early warning
from the NWS as it allowed time for her family to safely seek
refuge. The tornado tracked ENE of Hwy 78 and destroyed several
small farm buildings before impacting homes near the McGuire Loop
area. Near McGuire Loop and Rocky Glen Rd., the tornado knocked
down numerous power lines in trees before completely removing the
roof of one single-family residence. This is where the strongest
intensity of the tornado likely occurred with a maximum wind of
115 miles an hour. The tornado traveled to the NE portion of
McGuire Loop where pine trees were snapped. The tornado lifted
west of Hwy 87.

..Mount Hebron Tornado...

Rating:                 EF1
Estimated Peak Wind:    100 mph
Path Length /statute/:  0.76 miles
Path Width /maximum/:   30 yards
Fatalities:             0
Injuries:               0

Start Date:             02/16/2025
Start Time:             1:05 AM CST
Start Location:         3 SSE Douglas / Marshall County / AL
Start Lat/Lon:          34.133 / -86.3162

End Date:               02/16/2025
End Time:               1:11 AM CST
End Location:           3 SSE Douglas / Marshall County / AL
End Lat/Lon:            34.136 / -86.3035

Survey Summary:
The tornado rapidly developed along a line of severe storms
entering Southwestern Marshall County, first producing damage by
snapping several softwood trees along Mount Hebron Road. The
tornado continued along this road as it approached Mount Hebron
Douglas Road, snapping large softwood branches along its path.
The most concentrated damage occurred just northeast of the
intersection with Mount Hebron Douglas Road, where several farm
outbuildings and barns were destroyed. This was at and
immediately east of the intersection with New Clear Creek Road.
Here, a power pole was snapped about 5 to 7 feet from the top of
the pole. Also at this location, a cattle trailer was overturned
and moved several feet. A well-built farm outbuilding suffered
collapsed walls here at this location, and the combination of
this and the power pole led to the strongest point in this short-
lived tornado: 100mph winds and 30 yards in width. The tornado
continued northeast of this location to the farm next door,
destroying a small hay barn and another farm outbuilding across
the street. This particular building had a covered overhang and
was open on the end where the tornado approached, which
contributed to it's failing here. For this reason, the wind
speeds were lower than at the adjacent farm to the southwest. No
further damage was noted northeast of this hay barn location
between here and Chestnut Drive. 

Other damage was noted in the vicinity of Mount Hebron Road to the
north and the south, which was mainly large branches blown down or
sporadic trees here and there that were broken. This was determined
to be related to straight-line winds from the line of storms, as all
damage was noted to be laying in the same direction and not convergent
in nature. 

Thanks to Marshall County EMA for assistance on today's survey, 
and thanks to local news media for passing along both reports and 
videos from last night's event.

...NWS Damage Survey for 02/17/25 Tornado Event Update # 1...

.Update...So far one EF1 tornado has been confirmed in southern
Hale and Perry Counties. NWS meteorologists surveyed additional
damage in Greene and Sumter Counties and determined that it was
the result of straight line winds. A storm survey is scheduled
tomorrow for Elmore, Tallapoosa, Macon, and Montgomery Counties.
Additional surveys may be needed later this week.

.Overview...A fast-moving squall line moved through Central
Alabama late Saturday night ahead of a cold front. Very strong
wind fields with the system resulted in widespread damaging
straight line winds across Central Alabama, and all of Central
Alabama was under at least a severe thunderstorm warning at some
point during the event. Measured wind gusts were as high as 70 mph
at the Montgomery Regional Airport. At least one tornado has been
confirmed as well, with additional surveys needed in the coming
days.

.County Rd 10 EF-1 Tornado (Hale and Perry Counties)...

Rating:                 EF1
Estimated Peak Wind:    95 mph
Path Length /statute/:  18.37 miles
Path Width /maximum/:   200 yards
Fatalities:             0
Injuries:               2

Start Date:             02/16/2025
Start Time:             12:52 AM CST
Start Location:         4 S Cedarville / Hale County / AL
Start Lat/Lon:          32.5582 / -87.6852

End Date:               02/16/2025

End Location:           4 SW Marion / Perry County / AL
End Lat/Lon:            32.5918 / -87.3753

Survey Summary:
National Weather Service Meteorologists surveyed damage in
southern Hale and Perry Counties and determined that the damage
was consistent with a tornado. The start of the tornado was
estimated to be just west of Alabama Highway 69, where tree
damage was observed in an inaccessible area. The tornado
continued eastward, moving parallel to County Road 10. Along the
roadway, numerous trees were snapped or uprooted, along with at
least 40 to 50 power poles snapped. A site built home sustained
roof damage along with farm outbuildings that sustained
significant damage. The tornado gained strength as it moved east
of Alabama Highway 25, where EF-1 damage occurred. Multiple
manufactured homes were severely damaged due to large trees
falling on top of them, while another manufactured home was
destroyed due to tornadic wind gusts estimated around 95mph.
Residents who were inside the homes received the tornado warning
on their mobile phones, and were able to quickly take as much
shelter as they could. A mother and her two kids in one home took
shelter in their bathtub, which ended up being the only room in
the home that did not sustain major damage. 2 injuries occurred
where the homes were damaged, and the maximum width was estimated
to be 200 yards at this location. The tornado continued eastward
and crossed Alabama Highway 61 into Perry County. Minor tree
damage was noted along Jenkins Bryant Rd, and farm outbuildings
sustained major damage along Perry County Rd 23. The tornado
lifted along Lakeland Farm Rd, and no further damage was noted to
the east.

Severe T'Storm Warning (Tornado Possible)

It ain't over till it's over with these events.  I would probably go ahead and shelter for this one since it has shown some rotation...
