2.3 SSE Vincent - 2.6 NW St Ives National Weather Service meteorologists surveyed the damage in the vicinity of Vincent in Shelby County and Logan Martin Dam in Talladega County. The damage found was consistent with an EF-1 tornado with winds of 105 mph and was a regeneration of the Wateroak and Marvel supercell. The tornado touched down south of the town of Vincent on County Road 62, in Shelby County, where it uprooted dozens of trees. The tornado traveled to the northeast and dropped trees along the path. As it continued to the northeast into Talladega County, the tornado caused tree damage on the east end of Logan Martin Dam and continued through a couple of residential neighborhoods. Here, the tornado snapped and uprooted hardwood and softwood trees. The only home damage found and surveyed was due to fallen trees on Shaw Lane alongside Logan Martin Lake. Start: 33.3507/-86.4013 End: 33.4483/-86.3092

NWS EF Scale: F1

Event Narrative

A tornado initially touched down in northeastern Bibb County, near the community of Marvel and tracked northeast into western Shelby County. The tornado tracked north of CR 54 where it caused significant tree damage. Damage was consistent with winds of 105 mph and an EF1 rating. The tornado lifted in a field near Pea Ridge, along CR 10.

Episode Narrative

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.
