A powerful storm system roared across the Southeast United States on Wednesday, April 27, 2011. In the wake of this system, hundreds of people were left injured and/or homeless, along with approximately 100 people who lost their lives in the northern Alabama area alone. Some of the devastation was literally unimaginable with countless homes, neighborhoods and even portions of cities or towns either partially or completely destroyed. This storm system would be responsible for one of the largest and deadliest tornado outbreaks to ever impact much of the southeastern region.

The powerful storm system that affected the National Weather Service, Huntsville service area would actually occur in three separate waves of severe weather that day. The first occurred during the early morning hours of April 27, 2011 roughly between the hours of 2 AM and 8 AM CDT, while the second occurred during the late-morning to early afternoon period. The third and most devastating wave occurred during the afternoon hours on Wednesday, with some of the most violent and destructive tornadoes to affect the central Tennessee Valley area in recent decades.

The worst areas impacted by these storms included the towns of Phil Campbell and Oak Grove in eastern Franklin County Alabama, Mt. Hope in western Lawrence County and the Tanner Community in eastern Limestone County. Along a line connecting these areas tracked an EF5 tornado with peak winds around 210 mph, the strongest and most violent on the Enhanced Fujita Scale.
Other areas impacted by the storms include the city of Cullman, where extensive damage occurred to buildings in the downtown area, and to the town of Fairview, both of which are located in Cullman County. Downstream, further significant damage occurred to the Ruth and Oak Grove communities in Marshall County. In addition, the communities of Rainsville and Sylvania along with the towns of Henagar and Ider in DeKalb County were severely impacted. Fatalities in DeKalb County alone numbered at least 33 people. Furthermore, the towns of Flat Rock, Higdon and Pisgah in Jackson County sustained incredible damage. The tornadoes that affected these areas were rated as an EF4 with maximum winds near 190 mph.
In most of these areas alone, numerous people lost their lives. These represent just several of the communities and towns impacted by the events of April 27, 2011. While the majority of the analysis and survey work conducted by the National Weather Service, Huntsville and its partners have been completed, there will undoubtedly be countless research studies conducted by both academia and operational personnel in order to further evaluate and understand the complex processes associated with this near unprecedented severe weather outbreak.

Tornado in DEKALB, ALABAMA
From 27-APR-11 17:19:00 to 27-APR-11 17:56:00 (CST-6)
Location: TEN BROECK
Tornado F-scale: EF5
Property damage: 0.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

A violent long track tornado began in the Lakeview community northeast of Geraldine before tracking northeastward, generally parallel to and just east of State Route 75.  Along this line, the tornado passed through Fyffe, Rainsville, Sylvania, and eventually into northern DeKalb County south of the Cartersville community, killing 25 people. On the first day of surveys, the survey team noticed initial damage in the Lakeview community where the path width was generally around 50 yards.  This initial damage included mostly felled and snapped trees and structural damage to small buildings.  Extensive damage was noted especially in Rainsville and Sylvania where the path width was estimated to over 1/2 mile wide.  Damage in Rainsville included houses that were completely removed from foundations, with debris scattered for about one mile.  Near this location, trees were debarked and a few mobile homes were completely destroyed, with debris strewn for about a mile downstream.
A narrow corridor of intense damage extended from Skaggs Road to Lingerfeldt Road (also known as County Road 180), extending toward County Road 514.  Along Skaggs Road, a stone house was completely obliterated with much of the interior debris strewn well away from the structure.  A supporting large cement stone pillar was ripped completely out of the ground.  Another home along Skaggs Road was also leveled completely to the ground. The NOAA overflight showed significant ground scarring in this area and a walk through the nearby fields showed large pot marks and other sections of disturbed ground.
Slightly northeast along Lingerfeldt Road, numerous homes were leveled completely to their foundation with vehicles and debris strewn for hundreds of feet.  Overhead photos and follow-up visual confirmation revealed a mangled vehicle tossed well into a ravine and resting up in the remainder of trees.  At  1608 Lingerfeldt Road/County Road 180, a large two story brick home was completely obliterated with several of the supporting anchors ripped of the ground.  A concrete porch was ripped off with pieces strewn up to 150 yards.  A section of the asphalt driveway was pulled up.  In addition, an anchored liberty safe weighing 800 pounds was pulled off its anchorage and thrown into a wooded area 600 feet away.  When found, the safe's door had been ripped open and completely off.  A large pick-up truck at this residence was found mangled in pieces over 250 yards away in the same wooded area.  The residents of the home survived in a nearby storm pit.  Of note, the storm pit was partially exposed by the tornado with dirt being sucked up and pulled away around the opening.  Next door, a mobile home was completely disintegrated.  The residents of the mobile there also survived in a storm pit.  The section of damage from Skaggs Road to Lingerfeldt Road near the intersection with Crow Lane was deemed to be EF-5 intensity.   Severe damage with high end EF-4 damage was noted in a corridor from County Road 515 through a neighborhood along County Road 441.  In the east and south ends of the neighborhood, many one and two story homes were leveled to their foundation with debris scattered some distance.  Several cars were thrown a large distance in this area.  There was evidence of ground scarring as well as some sidewalk pavement pulled up in this location.  However, some of the homes in this area appeared to be pushed off their foundation initially with limited anchorage.
In the Sylvania community, similar situation occurred with houses completely removed from foundations and debris blown far downstream.  Some of these houses were connected to their foundations with anchor bolts and foundation straps, indicating a stronger construction of the homes.
Tornado damage continued from the Blake community, intersecting County Road 27, running parallel between State Highway 75 and Interstate 59 through Henager, Ider, to south of Cartersville.
In the Blake community, the tornado path width was estimated to be one half to three quarters of a mile.  Along County Road 27 just southeast of Sylvania, significant damage was observed .  All exterior and interior walls of several homes were completely destroyed with partial block and mortar foundations remaining.  In one instance, a concrete slab that served as a porch was displaced a few feet and broken in half.  Some hardwood trees in the area were stripped with no stubs of any branches remaining and were partially debarked.  The Mountain View Baptist Church sustained significant damage.  An old, one-story portion of the church dating back to 1902 and constructed of a brick and mortar exterior on wood frame walls was completely destroyed.  A recent two-story addition to the church was constructed in 2004 and consisting of similar building materials was partially destroyed, with most exterior walls and nearly all interior walls fallen.  A concrete block and mortar foundation was all that remained of a hallway adjoining the two buildings.

A violent tornado continued its wide path of violent destruction across the northern tip of DeKalb County in the Shiloh community.  The tornado killed 6 people in this area (12 total along its path across Jackson and DeKalb counties).  Several cinder block foundation homes and mobile homes were completely destroyed or swept away.  In addition, thousands of large trees were sheared off toward the base.  An older two-story and fairly well-built log cabin home was destroyed.  The top story of this home was lifted off, moved about 20 yards and twisted 180 degrees.  The lower story collapsed and was shifted off its foundation.  A senior citizen van was lofted and dropped into a field nearly 400 yards away.  At least 3 chicken barns collapsed with a high loss of livestock noted.  The tornado crossed into Dade County Georgia with a 1/4 to 1/2 mile wide path along County Road 155 north of Highway 75.

This long-track EF4 tornado that originated in Pickens county Alabama, moved through Blount county and weakened to EF1 intensity as it tracked northeast into southern Marshall County. This was the same tornado that did significant damage further southwest to the town of Cordova, in Walker County.
The tornado continued its track across the Blount/Marshall county line along a heavily wooded ridgeline between Highway 79 and Diamond Road. Aerial photography confirms the tornado tracked northeast along this ridgeline doing significant damage to a house just inside the Marshall County line, as well as snapping and uprooting numerous trees. The tornado crossed Highway 79 between mile marker 56 and 57, snapping a few trees and causing damage to the roof of a shed near a residence. Just northeast of this point, the tornado appeared to briefly strengthen (EF-2), completely destroying an industrial plant (Ferguson Industries).  The tornado continued northeast moving again over heavily wooded terrain just east of Highway 79. The damage path along this ridgeline can be seen from Highway 79 and aerial pictures confirm this track.
Beyond this point several miles south of Highway 431, little additional damage can be confirmed from this tornado. Radar data also suggests that this storm (supercell) was undergoing a transformation period causing the tornado to weaken and eventually lift.
This supercell later spawned another EF-5 tornado that devastated the town of Rainsville (DeKalb County) and moved northeast across the AL/GA state line.

This tornado decreased quickly in intensity as it moved into southeastern Franklin county after producing EF-3 damage in Marion county. Just after crossing the Marion/Franklin county line, the tornado collapsed two chicken houses and ripped roofing material off of two others nearby along highway 187. The tornado continued its brief track northeast and ripped much of the roof off of a two story home as it approached highway 172. Based on roof damage observed and widespread nature of large trees blown down or snapped off near their base, winds were estimated at 120 mph -- EF-2 tornado.   Another house nearby experienced significant roof damage as well.  The path width at this point was around 300 yards. As it reached highway 31, some minor shingle and home damage was observed. However, the tornado moved over a mainly forested portion of this area, continuing to snap/uproot numerous large trees, snapping several near their bases.
As the tornado moved toward Old Line Road, additional damage to houses was observed.  A few homes had portions of their roofs peeled off.  In addition, a mobile home was destroyed.  In this area a car was totaled by the tornado. Numerous large trees were snapped off or blown down as well.  A barn was heavily damaged by trees in this area as well.  The path width of the tornado was largest at this point and was estimated to be around 550 yards.  A path of numerous large trees being snapped or blown down continued just northeast of this road. The tornado appeared to gradually weaken and lift over the forested area northeast of Old Line Road as little additional damage was seen from ground surveys.  New satellite imagery reveals tree damage extending a little over 1/2 mile east of Old Line Road. Due to this new information, the end point was adjusted slightly east from its original point (5/17/12).

A violent long track tornado began it's life about 3 miles northeast of Section producing damage of EF-0 to EF-1 intensity with peak wind speeds of 70 to 90 mph, snapping or uprooting several softwood and hardwood trees.  The tornado rapidly intensified and began producing high end EF-3 to low end EF-4 damage within a matter of minutes, with peak wind speeds of 150 to 170 mph, and a path width of 1/2 to 3/4 mile as it roared into areas northeast of Pisgah and north of Rosalie.  Residents interviewed remarked that up to 3 tornadoes merged into one very large tornado.  There was evidence of this in the damage swath.
The tornado swarmed several mobile homes and block foundation homes in its path, snapping or uprooting thousands of trees.  Numerous trees were debarked in the process.  The tornado leveled at least 2 mobile homes and swept their remains hundreds of yards downwind.  Three were killed in 3 separate residences (6 total fatalities - 2 in Pisgah and 4 in the Higdon/Flat Rock communities).  Several vehicles were launched or swept several yards in different directions, in a few cases up to 50 yards.  The Friendship Church roof was heavily damaged.  Several farms were also affected, with barns and chicken houses heavily damaged or destroyed.
As the tornado continued its path, it intensified further on approach to Flat Rock and Higdon, producing damage of high end EF-4 intensity with peak winds up to 190 mph.  The tornado killed three from the same family at a residence southwest of Flat Rock.  The tornado mowed thousands in up to a 3/4 mile wide path.  One well-built block foundation home literally exploded as the tornado struck, lifting and sweeping all its structure and contents downwind, in some cases several hundred yards.  Miraculously, a mother and 3 children taking refuge in a hallway were completely unharmed.  At this farm, all fencing was destroyed and up to 19 cattle perished.  Two chicken barns were completely obliterated and swept away and unidentifiable.  A propane tank was lifted from the previous location of chicken barns and dropped over 100 yards away in front of the destroyed home.

Eight large metal power poles were bent over just above the base and several campus buildings had significant portions of metal roofing torn off.  A mid-rise under construction had its windows blown out, while the high-rise building sustained additional minor damage.  The connected construction crane remained standing.  To the south of the main track, in Hanceville proper, significant numbers of large pine, poplar and other hardwood trees were toppled onto houses.  The roof of the high school gym in town was partly destroyed and additional small buildings near downtown Hanceville sustained damage..
The tornado continued its track northeast from Hanceville, nearly paralleling Highway 91. Between Center Hill and Walter, large hardwood trees were found snapped and twisted. In addition along County Road 645, a barn was nearly destroyed. Continuing northeast along a path, just south of Holly Pond along Highway 91, a portion (1/3 to 1/2) of a residential shelter or shed was destroyed and a portion of a chicken house was badly damaged.
Additional damage was seen along County Road 1742 and 1753, several miles northeast of Holly Pond, and along Highway 231 in extreme northeast Cullman county. This damage is considered to be with the same complex of storms that rolled across the area during the early morning hours April 27th, however there is too much distance between damage points to be considered one long track tornado.

The violent tornado continued it's path from the Tennessee River along the Lawrence/Limestone county line northeast through Tanner and into the east Central portion of Limestone County.   Homes were completely obliterated along a wide swath in the Tanner community.  Nearly a dozen high tension power lines were snapped or taken to the ground in Limestone County.  Concrete power poles were also snapped off at their base.  A subsequent ground team, aided by a storm survey expert from the University of Alabama in Huntsville, surveyed the most intense damage in Limestone County.  High end EF-3 damage was noted over a large area in eastern Limestone County along and north of the East Limestone High School.  The intensity was maximized in Limestone County in the community of Tanner, with a large swath of EF-4 damage and a narrow corridor of high end EF-4 damage.  Several well-constructed homes with anchor bolting were completely wiped clean.  One home had the debris lofted over 300 hundred yards with large items carried completely away.  Intense ground scarring was noted in this area.  In addition, a large cargo container was picked up and blown approximately 600 yards and several cars were carried airborne for hundreds of yards.  In all, hundreds of homes received moderate to major damage along the path with many of these being total losses.

A violent long track tornado continued it's path from Marion County into southern Franklin County north of Hackleburg.  Significant devastation occurred throughout the city of Phil Campbell. Prolific damage was noted from the intersection of CR 51 and Alabama Highway 237, to the intersection of CR 81 and CR 75. Within a two mile corridor of either side of the railroad tracks the damage was significant. Within this corridor, several well constructed houses were destroyed.  Along Bonner Street, multiple block homes were leveled to the ground with the block foundations destroyed.  A twenty-five foot section of pavement was sucked up and scattered. Chunks of the pavement were found in a home over 1/3 of a mile down the road. The damage in this area was consistent with EF-5 damage.
In addition, at least three churches along the path sustained significant damage.   One church in Phil Campbell was completely destroyed with only the slab remaining.
Multiple mobile homes throughout the path were completely destroyed, and their mangled frames were tossed 25 to 50 yards.  Cars were tossed and destroyed throughout the path of the tornado, with one car wrapped around a debarked tree in Phil Campbell.   All along the path length, thousands of hardwood and softwood trees were snapped.  Hundreds of trees were also debarked and twisted, and had only stubs of the largest branches remaining.  EF-5 damage continued similarly northeast from Phil Campbell, roughly along County Roads 81 and 82 toward the community of Oak Grove.
In Oak Grove, the tornado may have reached a relative maximum in intensity well into the EF-5 category as the damage was slightly more intense and the path width was at a maximum of greater than one mile.  A large swath of complete devastation was noted in Oak Grove along County Roads 38 and Smith Lane.  A large well-constructed home with extensive anchoring was razed with debris carried well away from the site.  A Corvette sports car was mangled and thrown 641 feet (measured). A block home next door was also disintegrated.  Along Smith Lane a block home was wiped out and the only remains of a nearby chicken house was a small piece of a metal truss.  In this same area, the tree damage was significant and a large percentage of trees were stripped bare.

A tornado of EF-1 intensity produced wind speeds of up to 110 mph.  The tornado touched down just south of Section, crossing State Highway 35, then traveling nearly parallel to State Highway 71, through Dutton, into southern portions of of Pisgah before crossing into far northern DeKalb County.  The tornado uprooted and snapped numerous trees along its path, knocking out power in many locations. One fatality occurred in the Pisgah area associated with this tornado.
The tornado took a very similar track to a violent tornado of EF-4 intensity later during the afternoon of the 27th.  This made it very difficult to distinguish damage between the two tornadoes.  Several eyewitnesses remarked about the morning tornado location and damages.

Just south of the intersection of County Road 96 and State Highway 277, a mobile home was obliterated and another home collapsed.  Two other homes sustained structural damage along this section of road, two mobile homes were rolled on their side, and a metal barn was destroyed.
The tornado continued northeast and at the intersection of County Roads 255 and 256, the most significant damage was encountered and rated EF-4.  A residence just to the south of this intersection was reduced to its foundation.  A concrete slab at the front of the home was pulled up, and a set of concrete stairs was ripped from the foundation.  A compact car was thrown about 50 yards.
To the northeast of the intersection, two well-built and well-anchored homes were also reduced to their foundations.  A car was thrown approximately 50 yards across the street from one residence.  Several large trees were snapped off a few feet above the ground.  A third residence along County Road 256 had zero walls left standing.  Across the street from this home, a mobile home was completely demolished and strewn along County Road 256.
The tornado continued northeastward, destroying a cinder block garage and damaging a mobile home along 6th Street just southeast of Bridgeport.  The tornado crossed the Tennessee River, producing significant tree damage along County Road 91 before crossing into Marion County in Tennessee.

A family of 9 was in this house and 5 were killed. A trailer was missing and a metal-bolted garage was wiped clean of its foundation.  Along Frontier Road, a large brick home was nearly wiped clean off its foundation with several large trees ripped out of the ground and missing.  Further northeast along the path, along Walnut Ridge, a one-story home was severely damaged with the roof missing and a trailer that was tossed into a tree.  Several concrete power poles were bent over as the tornado crossed U.S. Highway 231, some bent at the base.  One the east side of Highway 231, a gas station building was completely demolished and two gas pumps were ripped from the ground and missing. The canopy over the pumps remained mostly intact.
