Shottsville A long track violent tornado touched down in Monroe County Mississippi, southwest of Smithville where it caused damage associated with an EF5 rating. The tornado moved northeast through Itawamba County before it crossed into Marion County, Alabama at a point near CR 93, southwest of Bexar. The tornado weakened to an EF1 rating as it entered Alabama, with winds of 110 mph . As the tornado tracked south of Bexar, a few mobile homes and outbuildings were damaged and numerous trees were snapped off and uprooted. The tornado moved across Corridor X/Future Interstate 22, near CR 33. As the tornado approached AL Hwy 19, 4 miles east southeast of Shottsville, it strengthened to an EF3 rating with winds of 160 mph, and destroyed several homes. This resulted in 6 fatalities. The tornado continued northeastward where it destroyed several single family homes and mobile homes along CR 20 and AL H ighway 187, 9 miles north of Hamilton. As the tornado approached the Marion/Franklin County L ine, several more houses were damaged and at least one chicken house destroyed near AL H ighway 187. Along the Alabama portion of the tornado path, hundreds of trees were downed, and at least 25 homes, mobile homes, and outbuildings were damaged or destroyed. The average path width of the Alabama portion of the tornado path was 0.5 mile (880 yds). The tornado continued into Franklin County Alabama (See Storm Data Huntsville), dissipating near Old Line Ro a d. This tornado decreased quickly in intensity as it moved into southeastern Franklin C ounty after producing EF-3 damage in Marion C ounty. Just after crossing the Marion/Franklin C ounty L ine, the tornado collapsed two chicken houses and ripped roofing material off of two others nearby along H ighway 187. The tornado continued its brief track northeast and ripped much of the roof off of a two story home as it approached H ighway 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 H ighway 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 quickly dissipate over the forested area northeast of Old Line Road as little additional damage was seen from ground surveys. However, vehicle access via roadways was not available to ascertain whether the track continued any further northeast. The total tornado damage path length was 37.10 miles and was rated an EF-5 in Monroe and Itawamba Counties of Ms. Start: 34.1677/-88.1932 End: 34.3233/-87.8982

NWS EF Scale: F3 (F5)

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.
