 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.

Several large hardwood trees were snapped off near the trunk base with extensive damage occurring in a concentrated path. The tornado continued its northeast movement and finally weakened to a EF-1 with a maximum wind speed of 100 mph as it dissipated at the foothill of Signal Mountain. A school and several homes suffered minor to moderate wind damage along the nearly 5 mile of the tornado. EPISODE NARRATIVE: A cold front tracked across east Tennessee during the afternoon and evening hours. The resulting squall line triggered numerous thunderstorm wind damage reports along with large hail. Three tornadoes were also reported. One person was injured.

 Brief Description: EVENT NARRATIVE: A storm survey conducted by the National Weather Service Forecast Office in Peachtree City, Georgia in cooperation with the Georgia State Patrol confirmed that the EF3 tornado, that originated in Polk county just east of Seney, and continued across extreme southeast Floyd county, continued into southern Bartow county. The tornado entered the county about 3 1/4 miles west-northwest of Taylorsville and finally lifted about four miles southwest of Cartersville. The tornado tracked approximately 11 miles across southern Bartow county. While no deaths or injuries were reported from the tornado in Bartow county, several mobile homes were heavily damaged and hundreds of trees and several high voltage power transmission lines were knocked down and there was damage to the Georgia Power Plant on Georgia Highway 113. In addition, the Taylorsville Elementary School sustained significant damage. Several homes sustained roof damage along Popum Road just north of Taylorsville, a number of trees were down along Euharlee Road, and several bulidings, a number of trees, and several street signs were down in the area of Woodland High School about three miles southwest of Cartersville. All together, there were approximately 55 homes damaged, six of which were destroyed, and 30 homes with minor damage. Two schools, as noted above Taylorsville Elementary and Woodland High School suffered heavy damage. Some Georgia Power high transmission towers were also down. EPISODE NARRATIVE: The pattern that began to evolve on March 14th continued and intensified on March 15th. A stationary front remained draped across north Georgia from near Atlanta to Athens. South of this front, the air mass was becoming increasingly warm, moist and unstable. Meanwhile, aloft, a low amplitude, yet vigorous short wave embedded within a fast zonal flow, was tracking rapidly eastward from the mid south into the southeast. Strong shear and high helicity combined with the unstable air mass and the frontal boundary to allow repeated severe thunderstorms to develop and track eastward along the boundary across north Georgia. The activity began early in the day as a complex of thunderstorms moved into the area from Alabama and continued until nearly midnight. As the day progressed, especially during the afternoon, the development of the activity gradually progressed further south and by midnight had reached the south and southeast parts of the state. Numerous severe thunderstorms and tornadic supercells were observed throughout the day. Historical records indicate that this was one of the most significant severe weather days for the Peachtree City Weather Forecast Office with more events and warnings than had been observed since May 2003.

 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 ground and aerial storm survey conducted by the National Weather Service Forecast Office in Peachtree City Georgia in cooperation with the Georgia State Patrol confirmed that the EF3 tornado, that first touched down in extreme north central Polk county just east of Seney, continued on an east-northeastward track across extreme southeast Floyd county. Approximately three miles of the 16-mile long path of this tornado was within Floyd county. The maximum path was once again estimated to be approximately 1/2 mile. Despite the relatively short time frame and small area of the county affected, considerable damage was inflicted to the far southeast part of the county. A home was destroyed on Old Wax Road, resulting in additional fatality and injury. Dozens of trees and several power lines were also down in this part of the county. Overall damage consisted of 20 homes, 10 of which were destroyed, and 10 with minor damage. EPISODE NARRATIVE: The pattern that began to evolve on March 14th continued and intensified on March 15th.

 Brief Description: EVENT NARRATIVE: A ground and aerial survey conducted by the National Weather Service Forecast Office in Peachtree City, GA in cooperation with the Georgia State Patrol and local emergency managers confirmed that an EF3 tornado had touched down in extreme north central Polk county, just east of the town of Seney near the intersection of Georgia Highway 101 and the Floyd county line. The tornado then tracked approximately 16 miles across extreme northeast Polk, extreme southeast Floyd, and into southern Bartow county before lifting southwest of Cartersville. The tornado had a maximum path width of 1/2 mile with maximum wind speeds estimated at 150 mph. EF3 damage was noted at three locations along the path of the tornado as it tracked across the three counties. The tornado made an approximate 3-mile track across far northern Polk county. Within Polk county, four homes were destroyed, two sustained major damage, five had minor damage, and 5 others were minimally impacted. All of these were in the far north central and northeast part of the county between Georgia Highway 101 and the Floyd county line where Bon Loop Road intersects the Floyd county line. One fatality and one injury occurred on Bon Loop Road where a home was destroyed. In addition, several county outbuildings, barns, shops, vehicles, one motor home, one travel trailer, one dog kennel business, several fences were heavily damaged. Several livestock were either injured or killed. Hundreds of trees and power lines were down in the area, including several high tension power lines support structures, which were heavily damaged.
