EF2 tornado, Danville Arpt to Morgan City, Alabama, March 24, 2023

From Danville Arpt to Morgan City, this EF2 tornado ran 4.9 miles across Morgan County on March 24, 2023, touching down at 12:33 AM CDT and reaching 125 yards wide. It killed nobody.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mphthis tornado

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded

A severe line of thunderstorms rolled through north Alabama during the late evening hours of the 24th into the early morning hours of the 25th, producing 7 tornadoes. An embedded supercell thunderstorm with a history of tornadoes in Mississippi moved east-northeast across northwest Alabama, yielding another two tornadoes in Lauderdale County in Florence and near Anderson. Associated with this line, multiple narrow swaths of intense damaging winds of 60 to 90 mph occurred across the Shoals metro area, including Sheffield, Tuscumbia, Muscle Shoals and Florence. The winds caused widespread power outages, damaged numerous structures, and toppled or snapped numerous trees, power poles and power lines. A few trees and power poles were dropped onto residences and vehicles, either destroying or heavily damaging them. Roof damages were reported at many locations as well. All told, an estimated #### million in damages occurred, the majority in northwest Alabama in Colbert and Lauderdale Counties. As the line continued east, additional tornadoes were spawned in Lawrence, Morgan, Jackson and DeKalb Counties.

A tornado tracked out of far east central Lawrence County into Morgan County. Minor damage was noted around Danville High School with the football scoreboard partially destroyed. The tornado intensified as it tracked east-northeast toward Targum Road. Uprooted trees, minor damage to a home, and a destroyed carport were observed. Tracking east, the tornado uprooted and snapped a significant number of trees along Iron Man Road and Forest Chapel Road. While there was heavy structural damage to single-family homes, the bulk of the damage was due to trees falling on houses. The tornado remained on the ground uprooting trees and tracking toward Vaughn Bridge Road. Near the Vaughn Bridge and Vest Road intersection, the tornado lifted and snapped the anchoring system of a single-wide mobile home. This caused the unit to overturn and roll, destroying the home. One fatality was reported at this location. Given the degree of damage, and strapping of anchors to the I-beam, the damage indicator held consistent with expected wind speed values. As the tornado tracked east, numerous trees were uprooted causing structural damage along Highway 31 and further east on Sparkman Street and through Bethel Road. The tornado likely lifted before the Bethel Road and I-65 intersection.

A tornado touched down on Highway 55 in Falkville and tracked generally northeastward. Initially, the tornado snapped trees and a small power pole in a yard on Highway 55. Farther to the northeast, the tornado did considerable roof damage to a barn at a residence on Chappell Road, and uprooted trees near the intersection of Chappell Road and Bert Stinson Road. The tornado then tracked along a largely wooded area, before snapping and uprooting trees on Nature Trail. There, the tornado also created roof damage to a small log cabin style home. ||Farther to the northeast, in a heavily wooded area to the north of Nature Trail, the tornado uprooted and snapped a long swath of trees nearly continuously before emerging into an open field, where it continued to snap and uproot trees along its path. In the open field, the tornado completely destroyed a large pole barn that contained 4x4 posts, some of which were anchored into the ground with cement. The walls of the barn were made of exterior metal sheeting with 2x4 wooden studs, which were toe-nailed into the 4x4 posts, and accompanied by a metal truss system. The barn contained 10,500lb hay bales which were blown downstream. A very large, old oak tree was uprooted adjacent to the barn. The width at its base was estimated to be 5 feet. ||The tornado continued to track generally to the northeast, snapping and uprooting trees along Wilson Mountain Road, which continued along the northeast adjacent and along Blankenship Narrell Drive. On Cottonwood Lane, trees were uprooted and snapped. One tree fell on an RV at a residence. From there, the tornado moved into a largely inaccessible heavily wooded area.

A National Weather Service damage survey assessed tornado damage in northeastern Morgan County. Damage was consistent with an EF-1 tornado with a peak wind speed of 94 mph.||Many damage indicators were in the form of uprooted trees and minor structural damage. The tornado touched down near the Highway 32 and Crisco Circle intersection. Tracking east-northeast, numerous trees were uprooted along Rescue Road. Near Rescue Road and Highway 231, an unanchored shed was destroyed. The tornado crossed the highway and uprooted many more trees along Old Silo Road and also damaged the roof to chicken houses. The tornado lifted just west of the Morgan-Marshall County line.

.NEAR TERM...
(Tonight)
Issued at 543 PM CDT Fri Mar 24 2023

A line of strong to severe thunderstorms continues to push east
across western Mississippi. Several supercell thunderstorms have
developed south of this line into central Mississippi as well
along a secondary warm front with the loss of daytime heating.
Despite some cooling early this evening in NW Alabama and near
the AL/MS border, the area may still have surface based
instability between 100 and 500 J/KG in place, especially south of
the Tennessee River. Plenty of effective shear is already in
place in NW Alabama of 40 to 60 knots. Effective shear has also
increased over the past hour to between 200 and 300 M2/S2 as well.

Timing for the main period of severe weather still looks to be
along and ahead of the pre-frontal trough axis that is currently
producing this robust convection over western Mississippi. This
would be mainly between 10 PM and 5 AM on Saturday. The strength
of the low/mid level wind fields suggest some very strong wind
gusts to between 65 and 75 could be possible where we remain
surface based. This may be more south of the Tennessee River, but
several models show very meager CAPE around 100 to 200 J/KG
remaining in place as far north as southern middle Tennessee
overnight. Main threats will be damaging winds and tornadoes.
Though, some large hail might occurred overnight if MUCAPE get
around 1000 J/KG just ahead of the pre-frontal trough axis. Very
heavy rainfall rates are also expected over the area. Though the
area of convection is expected to accelerate and move more quickly
overnight, the very intense rainfall rates could cause some
flooding given (current flash flood guidance of 1.5 to 2.5 inches
in most locations).

Given radar trends and the environment, expect a watch (likely a
tornado watch) to be in place between 9 and 10 PM CDT.

.SHORT TERM...
(Saturday through Monday)
Issued at 300 PM CDT Fri Mar 24 2023

After the main line of thunderstorms clear out Saturday morning,
gusty winds up to 45 mph will remain despite lack of rain. With
saturated soils and weakened trees, this time will be particularly
of concern as trees will be at risk of falling more easily than
normal. The aforementioned Wind Advisory is set to expire at 12Z
(7 AM CT) due to gusts dipping below criteria by this time.
Despite being below criteria, Saturday will be a windy day with an
increased pressure gradient over our area. High temperatures are
expected to climb into the mid to upper 70s with mostly clear,
post- frontal skies. The dry weather may be short- lived, however,
as Sunday afternoon brings a low chance (15-20%) for rain south
of the TN River due to a potential stalled boundary in Central AL.
These chances will increase both in likelihood and area in the
evening and overnight, reaching medium chances of 40-60%. By
Monday, rain should clear out NW to SE as a secondary cold front
moves through and continues southeast, allowing a return of mostly
sunny skies.

&&

.LONG TERM...
(Monday night through Friday)
Issued at 300 PM CDT Fri Mar 24 2023

Monday night low temperatures will dip into the upper 40s to lower
50s before a short-lived pattern change begins for the mid-week.
As high pressure builds in from the NW, more seasonal temperatures
(as opposed to above-normal) are expected. Highs are expected to
be in the 60s both Tuesday and Wednesday before beginning to warm
up above-normal again Thursday, reaching the lower 70s as the high
pressure continues eastward. Confidence is still low at this time,
however, by the end of the long-term period, there may be another
system moving through with the capability to produce strong to
severe storms. We will continue to monitor this potential in
future forecast updates.

.AVIATION...
(06Z TAFS)
Issued at 1130 PM CDT Fri Mar 24 2023

Band of strong to severe TS will continue to track east, including
the KHSV vicinity, and exiting northeast AL by ~08-09Z. Wind gusts
of 40-60kt are possible in a few locations along this band, along
with +RA and frequent lightning. IFR conditions are likely as this
moves through. Improvement to VFR will occur shortly after, but
with continued gusty southwest wind flow at times. Gusts of
25-30kt are possible through the day Saturday before diminishing
by 00Z.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
