2011-04-27 · near Cluttsville, Madison, Alabama
Event narrative
The tornado crossed in Madison County east of Limestone County Prison'along Orvil Smith Road with a path width of mile. The tornado maintained an EF-3 strength with winds of 140 to 160 MPH and a path width between and mile for much of its track northeast across Old Railroad Bed Road and Ford Chapel Road, before narrowing to around 300 yards in Anderson Hills. Dozens of well-constructed homes were destroyed, in some cases with all exterior walls collapsing in both single and two-story homes. At least 3-5 mobile homes were either destroyed or swept completely clean with no evidence of debris. At least 2 other well-constructed homes had complete wall collapse in Anderson Hills and were shifted off their foundation. This damage was once again consistent with low end EF-4 wind speeds of around 170 MPH.
Numerous tall pines and other hardwood trees were snapped, uprooted and debarked along the entire path. The path width widened once again to around mile as the tornado tracked through residential areas along Bald Eagle Lane, Old Eli Road and Ginnery Row. At least 2 of these homes had complete wall collapse, but these structures had foundation straps and nails in lieu of bolts. At least one fatality was confirmed at one of these residences. Eight additional fatalities occurred in Madison County along the track of this violent tornado. The damage was consistent with high end EF-3 wind speeds between 140 and 160 MPH. The tornado lifted just south of the Patterson Lane after twisting irrigation equipment and snapping additional trees. Just to the northeast of this location, the tornado touched down again as an EF-0 tornado with peak wind speeds of 70 MPH. Along Grimwood Road and Walker Lane, south of Hazel Green, the tornado uprooted and snapped several trees. The tornado weakened or may have lifted briefly across extreme northeast Madison County before re-strengthening again as it entered Lincoln County in Southern Middle Tennessee.
Wider weather episode
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.
