Brief Description: EVENT NARRATIVE: Representatives from the National Weather Service and the Jackson County Emergency Management Agency conducted a storm survey of damage that occurred in Jackson County, Alabama early in the morning of February 6, 2008. The damage was determined to originate from a strong tornado, which at its peak had winds of at least 180 MPH, giving it a rating of EF-4 on the Enhanced Fujita Scale. The most significant damage occurred at the corner of County Road 60 and 177, between the Rosalie and Pisgah communities in eastern Jackson County. This is also approximately the location where one fatality occurred. Trees along the tornado path were snapped and in some cases shredded, several houses were swept from their foundations, and a large section of a chicken house collapsed. Several large hay bales (weighing 2,500 pounds) were blown apart or tossed around. EPISODE NARRATIVE: The WFO Huntsville County Warning Area experienced the worst tornado outbreak in 19 years on February 6, 2008. While the number of observed tornadoes was low (4), the area experienced two EF-4 tornadoes, the first time the area has witnessed more than one devastating tornado on the same day since 1974. This event was part of a large tornado outbreak which spanned both February 5th (Super Tuesday) and 6th (Wednesday). A series of tornadic supercell thunderstorms swept across the Mid-South and Southeast states ahead of a potent cold front. | |||||||||||

Brief Description: EVENT NARRATIVE: A damage survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia confirmed that a brief EF2 tornado had touched down approximately one mile southeast of Summerville and tracked less than one mile almost due east. The tornado was determined to have a maximum path width of 200 yards with maximum winds estimated to be 120 mph. Considerable damage was noted in the Summerville area. Over 30 homes were damaged along with 10 businesses. Most of the damage to these structures was determined to be minor. The majority of the damage occurred on Commerce Street. The brick wall of a car care center collapsed, the roof was shifted and lifted from a lumber warehouse, and windows were blown out of a barbecue restaurant. All of these events occurred on Commerce Street. At the intersection of Cleghorn and Scoggin Streets nearby, a single-wide mobile home was completely destroyed. Although the mobile home was anchored, the metal frame was ripped from the foundation and the home was tossed on its side. EPISODE NARRATIVE: A vigorous upper closed low was moving from the mid-south and Mississippi valley region into the mid-Atlantic and southeast U.S. A strong cold front accompanied the upper system. A strong low-level jet in advance of these weather systems transported warm, moist Gulf air northward into the region. With strong dynamics, hence shear, combined with an unusually moist, unstable atmosphere, the atmosphere was primed for a major weather outbreak. One round of thunderstorms passed through north Georgia during the early morning hours. A few minor severe weather events accompanied this system in northwest Georgia. Partial clearing followed the morning convection, allowing temperatures to soar into the mid 70s across much of north and central Georgia in advance of the main weather system. Scattered to numerous discrete supercell thunderstorms developed during mid-afternoon in northwest Georgia and progressed east and southeast across the remaining portions of the county warning area during the evening hours. Severe thunderstorms and tornadoes lingered into the early morning hours of the 11th across the southern counties of central Georgia. During the eight hour period from 5 pm EDT on April 10th to 1 am EDT on April 11th, a total of 14 tornadoes were confirmed to have touched down in north and central Georgia causing millions in damages. While some injuries were observed, no deaths were observed. | |||||||||||
