EF5 Tornado — Lawrence, Alabama
2011-04-27 · near Mt Hope, Lawrence, Alabama
Event narrative
The violent tornado continued to track northeast from Franklin County into Lawrence County as an EF-5 near the Mt. Hope area where significant devastation was incurred to single family homes and a restaurant. Nothing but the foundation and a pile of debris remained in this area, and a small portion of the restaurant foundation buckled. Thousands of hardwood and softwood trees were snapped, with a significant number of trees twisted and debarked with only stubs of branches remaining. Many mobile homes were also destroyed with the frames mangled, and a single family home was completely destroyed with the walls and contents strewn over a hundred yards. Further northeast the damage was slightly less intense, with more trees snapped and twisted as the tornado reached Highway 24. At this location multiple chicken houses were completely destroyed with much of the debris wrapped around debarked trees. TVA high voltage power line trusses were also destroyed at this location. As the tornado continued northeast more significant damage occurred in and around the Langtown community north of Moulton. On the west side of Alabama Highway 33, several homes sustained significant damage with roofs missing or only interior rooms remaining. A nearby store and gas station also sustained significant damage. The tornado strengthened again to a high end EF-4 as it moved over County Roads 214 and 298, where multiple houses and mobile homes were completely destroyed. Several cars were tossed into fields and wrapped around trees along County Road 291 and 292. One vehicle was tossed into a large hardwood tree that was also debarked. Tree and mobile home damage continued along County Roads 217 and 222, where a handful of large high tension TVA power poles were destroyed. Sustained EF-4 damage continued northeast towards Alabama Highway 20, where a restaurant was completely destroyed and two single family houses were significantly damaged. Tree damage continued into extreme northeastern Morgan County.
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.
