A powerful storm system crossed the Southeast United States on Wednesday, April 27, 2011, resulting in a large and deadly tornado outbreak. This epic event broke the record for number of tornadoes in a day for the state of Alabama, becoming the most significant tornado outbreak in the state���s history. ||Central Alabama had two rounds of severe weather that day. During the early morning hours, a Quasi-Linear Convective System quickly moved across the northern half of the National Weather Service, Birmingham county warning area. Straight line winds of 90 mph (78kts) or greater and 11 tornadoes lead to widespread damage and power outages. During the afternoon, long-lived supercell thunderstorms produced long-track, strong and violent tornadoes. Destruction and loss of life across many towns and communities was devastating. ||The hardest hit areas included Shottsville and Hackleburg, both in Marion County, where winds of 160 mph and 210 mph respectively, caused unimagineable damage. Cordova, in Walker County, was hit twice; by a tornado along the Quasi-Linear Convective System during the early morning hours and again in the afternoon by a long-track EF4 tornado. A long track tornado moved across the city of Tuscaloosa and the western suburbs of Birmingham, resulting in the complete destruction of whole neighborhoods and numerous injuries and fatalities in those heavily populated areas. The same parent supercell produced another violent tornado in east Central Alabama as it tracked across St. Clair and Calhoun Counties, resulting in additional fatalities and incredible damage to a number of neighborhoods. Another violent EF4 tornado tracked across portions of Elmore and Tallapoosa Counties, including Lake Martin, destroying numerous homes and a large section of a mobile home park. ||Most of the violent tornadoes from this day were captured on video by a number of people, including storm spotters and chasers, as well as numerous television news crews and remotely controlled web-enabled video cameras. This allowed unprecedented coverage and viewing of this historic event in real time from people worldwide.

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.

A stationary front remained draped across Southern Missouri into Western Kentucky from April 24th, 2011 into April 25th, 2011. A very warm and unstable atmosphere was in place across the Mid-South ahead of the front. A low pressure system developed along the front and interacted with the unstable environment which helped produce several rounds of severe storms into the evening of April 26th, 2011. As a result of the severe storms, the front sank south during the early morning hours of April 27th, 2011 as a secondary low pressure system developed along the front. As a result, another round of severe storms fired during the afternoon hours ahead of the low pressure center. Additional severe storms fired along the trailing cold front. Tornadoes, large hail, damaging winds, flash flooding occurred as a result of the severe storms.

A tornado initially touched down west of Hamilton in southwest Marion County and moved northeast where it caused devastating damage to the city of Hackleburg. The tornado continued into Franklin County and tracked through Lawrence, Morgan, Limestone, and Madison Counties in Alabama. The tornado continued into Lincoln County Tennessee and finally dissipated in Franklin County Tennessee (See Storm Data Huntsville). The average path width of the tornado while in Marion County was 0.5 mile (880 yds). The tornado touched down west of AL Hwy 19 near Sipsey Creek and moved northeast and crossed Corridor X/Future Interstate 22. Here it caused significant tree damage. The tornado strengthened north of Hamilton and caused roof damage to at least one home. The storm strengthened further as it approached US Hwy 43, southwest of Hackleburg, to a violent EF4 rating with winds estimated at 170 mph. The tornado tracked parallel to US Hwy 43 toward Hackleburg and strengthened more to an EF5 with winds up to 210 mph, as its path widened to 0.75 mile (1320 yds). Several subdivisions and businesses, Hackleburg High School, Middle School, and Elementary School, and the Wrangler Plant were destroyed. Vehicles were tossed up to 200 yards. One well built home with 4 brick sides was completely leveled and the debris from the home was tossed over 40 yards to the north. The tornado moved northeast of Hackleburg and continued to parallel US Hwy 43. It crossed into Franklin County just east of the highway. Along the damage path in Marion County, thousands of trees were downed, several hundred structures were damaged, and at least 100 of these structures were completely destroyed as many homes were leveled. Eighteen fatalities are attributed to this tornado in Marion County, as well as numerous injuries.

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.

After lifting for 4 miles, a violent EF-5 tornado touched back down southwest of Smithville and moved northeast. The town of Smithville was almost completely destroyed by the tornado. Homes and businesses were completely wiped off of their foundations. The town hall, post office, police station, and four churches were destroyed. All appliances and plumbing fixtures in the direct path of the tornado were shredded or missing. Granite tombstones were knocked down in the opposite direction of the tornado passage. A ford explorer that was parked a half mile away from the town's water tower was picked up by the tornado and thrown into the top of the water tower. The vehicle was then thrown an additional few hundred feet. In total, 117 structures were destroyed with an additional 50 structures sustaining major damage. Numerous other structures sustained minor damage. Trees were debarked, twisted, and snapped. Power lines were knocked down and the town's water system was destroyed. A lot of the homes that were destroyed were well built, bolted to their foundations and were less than 10 years old. A total of 16 fatalities occurred from the tornado. Thirty-seven injuries occurred as well. The tornado continued northeast after destroying Smithville and crossed into Itawamba County, Mississippi.

A violent tornado moved northeast from Monroe County, Mississippi into Southeast Itawamba County. The tornado weakened as it moved through Itawamba County. Numerous trees and power lines were knocked down. One home sustained roof damage. The tornado continued northeast and crossed over into Marion County, Alabama.
