Tornado Surveys Compiled From Friday Night/Saturday Morning

Here are some links to information about the Arkansas and Iowa tornadoes.

The information for our region is below. The Memphis office still has a lot of work to do, and I'd ask everyone to be patient with them and the Nashville office, as surveying damage from this bad an outbreak is a lot of hard work. 

Pretty sad stuff seeing that even some site-built homes in both the Waynesboro and the Hazel Green/Huntland tornado were completely destroyed by winds of "only" E/F2-F3 strength. One person even died in one of those houses that was completely blown up. 

Something is wrong with that picture. I think we need better building codes, and for those to actually be followed, in tornado-prone parts of the world. And until that happens, I hope the trend will continue for more shelters to be available to people who are willing to use them, especially in poor parts of towns where nobody can afford to buy a storm shelter for their home. New schools are being built with tornado shelters that are about as strong as a bank vault (and I've seen people interviewed who survived F-5 winds in a bank vault), so I know that progress along these lines is possible. 

Alabama has a lot of storm shelters, but Tennessee still does not have many. It looks like Mississippi may have a little more than Tennessee, but not by much. If we're going to say we care about people's lives being protected during these tornado outbreaks, then having adequate shelter is part of the equation. If people get the warnings and are willing to take shelter, but do not really have a safe enough place to go, then we are back to the drawing board. 

The injuries from the Hackleburg/Bear Creek (F-1, high-end) and Boaz/Sardis City (F-0) tornadoes all happened in trailers. And we expect that. Never want anyone to stay in a mobile/manufactured home during a tornado.

Survey Summary:




A National Weather Service, Madison County EMA, and Lincoln


County EMA damage assessment team found evidence of an


EF3 tornado in Northern Madison County and Southeastern Lincoln


County. Peak winds were estimated at 160 mph on Borderline Rd.




The tornado began west of Highway 431 and south of Elkwood


Section Rd where multiple trees were uprooted and several trees fell


on homes. On the eastside of HWY 431, near the Lincoln Rd.


intersection, numerous structures were heavily damaged including multiple 


stores which sustained major damage. This includes a


collapse of walls and roofs displaced with debris


thrown eastward. Given the degree of damage at this location, a


mid-range EF3 rating was reported. The tornado tracked east-


northeast through Mulberry Rd. Along this path, the tornado


uprooted and snapped numerous trees and caused significant roof


damage to a single-family home. Unfortunately, the tornado


continued to intensify on route to Borderline Rd. which is along


the Alabama and Tennessee border. At this location, heavy damage


was noted where houses were heavily damaged and two homes


experienced a complete collapse of walls, destroying the


structures. One fatality was reported at a single-family home


along Borderline Rd. where the structure was destroyed. The


tornado's estimated peak wind of 160 mph was noted at the


intersection of Borderline Rd and Myers Rd where a newly


constructed, however not completed, home was destroyed with a


complete collapse of walls. The degree of damage at this location


was slightly lowered below expected values due an uncertainty in


the status of the garage, which was facing west. The tornado


continued eastward just north of the Stateline, paralleling


Borderline Road as it continued north/east. Sporadic trees were


uprooted and snapped south of Vanntown, crossing Hester Creek.


The tornado destroyed several farm/outbuildings housing farm


equipment from Mason Road eastward onto Echols Road. The tornado


was weakening at this point, and finally lifted just after it


crossed John Hunter Highway/Hwy 122 just south of Elora in far


southeastern Lincoln County. Tin was strewn into an open field in


this location, but no further tree/structural damage was noted


beyond the tree line near Collins Road and Mountain Road.

Survey Summary:

This major, long track tornado began in McNairy County and

continued across Hardin County before moving into Wayne County

southwest of Clifton. Please refer to NWS Memphis damage surveys

for more information on the McNairy and Hardin County portions of

this tornado path. The tornado entered Wayne County around 2 miles

south of Clifton and continued northeast, passing across Highway

641 near Tom Holt Road where several homes and outbuildings were

heavily damaged and dozens of trees blown down. Further northeast,

the tornado struck the Leatherwood community along Beech Creek

Road, where a few poorly constructed homes were leveled and others

heavily damaged. One woman was critically injured in this area and

airlifted to the hospital. The tornado then crossed Highway 13

about 6 miles north of Waynesboro before moving through the Topsy

and Ashland communities, snapping and uprooting hundreds of more

trees. The tornado entered Lewis County along Cothran Road and

continued northeast across Seiber Ridge Road, Rockhouse Road,

Howard Switch Road, Buffalo Road, and the Natchez Trace Parkway

at Summertown Highway, blowing down hundreds of more trees and

damaging several homes and outbuildings. The last damage was seen

on Tiger Bennett Road, although reports indicate the tornado may

have continued further to near the Maury County line before

lifting. The tornado path length and width will be refined over

the coming days as newly available satellite and drone imagery

becomes available.


Special thanks to the Wayne and Lewis County EMAs as well as the

PERILS project for their help with this damage survey.

Survey Summary:


NWS personnel have surveyed the damage in Marion and Winston


Counties and determined that the damage was caused by an EF1


tornado with maximum wind speeds of 110 mph. The tornado began on


Marion County Road 348 west of AL Highway 253 south of 


Hackleburg, where minor tree damage was noted. The tornado rapidly


increased and caused significant damage as it crossed AL Hwy 253,


uprooting several trees and causing superficial damage to a home 


on the edge of the track. The tornado continued east- 


northeastward along Union Hill Road, crossing the twisting road 


twice before the intersection with Chalk Mine Road. Damage in this


segment of the path consisted solely of pockets of tree damage 


which varied in intensity but was easily identified as tornado 


damage. As the tornado paralleled Chalk Mine Road, it produced 


more widespread tree damage, and destroyed a manufactured home 


that was exposed on a knob of a hill. The damage to trees 


surrounding the manufactured home was minimal, which contributed 


to a below expected value or 100 mph assigned to the flipping and 


tossing of the home. The tornado continued across the Fairview 


community causing significant tree damage just east of County Road


12, with a grove of pine trees all being sheared off about 20 


feet above ground level. The tornado then continued over 


inaccessible areas south of County Road 6 as it headed towards the


Lumbull community, crossing Alabama Highway 241 just south of 


Lumbull. As it approached Bear Creek, it continued to cause sparse


but notable tree damage. The most significant damage along the 


entire path occurred along Alabama Highway 13 south of Bear Creek,


where a large metal building structure received significant 


damage to the windward side of the building. Winds in this area 


approached 110 mph, bringing this tornado to a high end EF-1 


tornado. The tornado then crossed AL Hwy 13, where an individual 


received major injuries as the manufactured home being occupied 


was flipped upside-down. The tornado continued eastward, crossing 


Old Union Road, then paralleling County Line Church Road until the


tornado passed into Winston County, snapping and uprooting trees 


in a continuous but sparse pattern. A few homes and outbuildings 


were affected either by minor wind damage or trees falling on 


them. The tornado weakened somewhat as it crossed the county line,


and the damage path widened. As it approached the vicinity of 


Posey Field, the tornado seemed to intensify locally, uprooting 


several trees in a residential neighborhood. The tornado crossed 


Airport Road, damaging trees and a detached garage at a residence.


The tornado continued eastward through the Center community, with


damage decreasing and becoming more sporadic before eventually 


dissipating just north of County Road 68 just west of Alabama 


Highway 195




.Tornado #2 Sardis City Tornado...




Rating:                 EF0


Estimated Peak Wind:    85 mph


Path Length /statute/:  3.10 miles


Path Width /maximum/:   250 yards


Fatalities:             0


Injuries:               2




Start Date:             04/01/2023


Start Time:             04:51 AM CDT


Start Location:         1 SSE Boaz / Etowah County / AL


Start Lat/Lon:          34.1805 / -86.1494




End Date:               04/01/2023


End Time:               04:55 AM CDT


End Location:           2 ENE Sardis City / Etowah County / AL


End Lat/Lon:            34.1829 / -86.0957




Survey Summary:


A damage survey conducted in the Sardis City area of northern


Etowah County revealed an EF0 tornado that occurred on the morning


of April 1. The damage path began with an uprooted tree along


Coosa Road before moving across Highway 431, where a shop had


large doors blown out and a church had the roof partially removed.


At Morningview Drive and Hood Drive, several homes had significant


roof damage and numerous trees were uprooted. A shed was blown


several yards and destroyed, a fence was blown down, and one home


had failure of the west facing garage door which caused the roof


to be removed and walls to collapse. More trees were downed in a


wooded area before the tornado moved along Patterson Street. Here,


one home sustained roof damage, a silo was damaged, a metal shed


had significant damage to the southeast corner, and a tree fell


through another home's backyard privacy fence. Many hundred-year-


old trees were uprooted around both homes. Another home was 


damaged by a falling tree at the corner of Patterson and Church 


Road. More trees were downed across Parkway Drive and Alexander 


Drive. Two pine trees fell through two mobile homes on Alexander 


Drive. Two people were injured in one of the mobile homes. A few 


more pine trees were uprooted, with smaller limbs snapped off as 


well, across Kristie Lane and Oak Drive. At Horton Circle, 


numerous trees were uprooted, and a house sustained minor shingle 


damage. The damage path ended after crossing Broadwell Road near 


the Sardis Drive intersection.
