|Brief Description: EVENT NARRATIVE: The tornado first touched down at approximately 1415EST in northwest Pierce County near Merson Road and Crump Road. Several trees were damaged and a farm shed had portions of its sheet metal roof removed. Winds here were estimated to have been near 70 mph or EF-0. The tornado moved northeast across several fields and encountered two small farm structures and a wooded area along Tiny Lane. The structures were completely destroyed with their contents strewn across the wooded area. Extensive tree blow down occurred in the woods with many pines snapped at 10 to 15 feet above ground level. The tornado was estimated to have been an EF-1 event in this location with winds of 110 mph. The funnel continued to move across fields next encountering wooded areas and structures near Scuffletown Road. At this point the funnel was one quarter mile or approximately 440 yards wide with winds estimated at 105 mph. Extensive tree blow down continued here with one mobile home destroyed and substantial damage to a wood frame structure. The tornado crossed the Big Satilla Creek at this point, and crossed into Appling County, continuing on a northeast track. EPISODE NARRATIVE: Strong mid and upper low initially over Texas was moving east-northeast while the upper level trough it was embedded in became negatively tilted. This led to a broad diffluent pattern over most of the southeastern states. As the system approached the right rear quadrant of upper jet moved into the forecast area coincident with a low-level jet of, at least, 60 knots. This created atmospheric dynamics favorable for severe weather, with the only limiting factor being modest instability. A warm front over the area during the morning moved rapidly north in response to increasing southerly flow allowing a gradual increase in low level instability. By afternoon several severe weather events and three tornadoes occurred over portions of southeast Georgia.|

|Brief Description: EVENT NARRATIVE: The tornado first touched down at approximately 1415EST in northwest Pierce County near Merson Road and Crump Road. It crossed the Big Satilla Creek, entering into Appling County at this point, and continued on a northeast track. The funnel may have briefly lifted off the ground at this point. The next significant damage occurred along Metts-Overstreet Road with the complete destruction of a singlewide mobile home and a farm shed at approximately 1425EST. Additionally, at this location, a brick cider block structure had one wall knocked over. The tornado then moved into a dairy just west of the intersection of State Road 15 and Wireglass Road. The event was rated as an EF-2 with winds of 135 mph at this location. Three metal building structures were destroyed with one removed from its foundation and blown into a pile of scrap metal. It is possible the funnel may have approached EF-3 at this particular location with winds of 140 to 150 mph; however, other damage to frame and masonry structures at the dairy suggested a lower wind value should be assigned to this area. One individual escaped injury by jumping into a depressed area inside one of the structures before it blew down around her. East of State Road 15, along Wireglass Road, extensive tree blow down and snapping continued in a tree farm. Once again the funnel likely lifted off the ground touching down again at 1430EST near 4230 Antioch Church Road destroying a doublewide mobile home. At this location, two middle aged individuals were in the bedroom, preparing for work, when the funnel destroyed the mobile home. Both escaped with only minor cuts despite the fact that the doublewide was completely obliterated and the frames bent. Once again at this location the winds were rated at 135 mph for a strong EF-2 rating.

|Brief Description: EVENT NARRATIVE: A survey team from the National Weather Service Office in Charleston, South Carolina along with other damage survey experts from across the country determined that the Tornado that struck McIntosh county Georgia on Sunday morning May 11, was a violent EF-4. The Tornado beginning and end times are based on radar data combined with credible ground truth reports. The Tornado formed at 952 am, approximately 3 miles northwest of Darien, Georgia and tracked east about 11 miles before dissipating at 1007 am as a water spout in Doboy Sound. The Tornado formed in a wooded area about a half mile west of Route 251 where numerous trees were snapped off. The Tornado strengthened rapidly as it approached and moved across Route 251. The Tornado struck a Marine Sales and Services Business located on the east side of Route 251. The bolts for all but one of the anchored metal support beams for the metal building were snapped off just above the concrete slab. With the exception of the one metal support beam that was bent to the ground, the slab was wiped clean. Approximately 50 boats were tossed around and destroyed, with one 18 foot 4000 pound boast carried about 650 yards into some trees. A 32 foot 8000 pound boat was carried about 130 yards onto the top of the Gateway Behavioral Services Building. A vehicle that was parked in the parking lot was carried in the air 150 yards. One 125 horsepower boat motor weighing 300 to 350 pounds was carried 250 yards and deposited into the roof of a building. In addition, one of the boats had yet to be accounted for at the time the survey was conducted. Several other vehicles near the business were rolled or tossed and severely damaged or destroyed. No one was in the building at the time the Tornado struck and damage to the building and all the boats were estimated to be 5 million dollars. Approximately 100 yards to the south-southeast of the Marine Sales and Services Building, the McIntosh Emergency Medical Services Building was destroyed by the Tornado with damage to three ambulances and one fire truck. Many of the metal support beams from this facility were torn from the concrete slab or snapped off. This building was rated for 120 mph winds. No one was in this building at the time of the Tornado because they were out on a non weather related call. The Gateway Behavioral Health and Services Building was totally destroyed. This metal framed building with brick exterior was located about 100 yards east-northeast of the McIntosh Emergency Medical Services Building and 130 yards east-southeast of the Marine Sales and Services Building. The roof of the Gateway Building collapsed along with many of the outer brick walls. Many of the large load bearing metal beams were bent or knocked down. Portions of the metal roof were carried a mile away onto Interstate 95. Some of the roofing material was found 11 miles away on Sapelo Island. Of the 12 people that were in the building when the Tornado hit, 9 were injured sustaining broken bones and or lacerations. Six vehicles around this building were damaged or destroyed and a metal light pole and several trees were snapped off in this area. Two other businesses in this area suffered damage including damage to satellite dishes and two overturned tractor trailers. Damage to the Marine Sales and Services Business and the Gateway Behavioral Health and Services Building indicated that EF-4 damage had occurred with winds estimated to be between 170 and 180 mph. After leaving this area the Tornado traveled east and weakened. The Tornado reached its maximum width of 700 yards as it crossed Interstate 95, and then decreased in size and was mainly from 200 to 500 yards wide during the remainder of the path. The Tornado damaged or destroyed four billboards along Interstate 95, produced mainly minor roof damage to several dozen homes mainly in the Ridgeville area, snapped off or uprooted thousands of trees, some of them falling on homes or vehicles, and damaged or destroyed numerous outbuildings. A resident of Ridgeville, Georgia whose home suffered minor damage in the Tornado, took shelter in a closet after seeing a National Weather Service Severe Weather Statement on the television mentioning that Ridgeville was in the path of the Tornado. The Tornado also damaged the Blue-N-Hall Marina and Fishing Dock. In this area, a large boat hoist along with 18 boats and several boat trailers were damaged or destroyed. Several power poles were also snapped off and several vehicles were damaged. Numerous trees were also snapped off on Hird Island. The Tornado likely dissipated over Doboy Sound as a waterspout. Besides portions of the Gateway roof, lots of other debris including signs were deposited on Sapelo Island. EPISODE NARRATIVE: A warm front lifted northward through southern South Carolina and southeast Georgia during the morning, with a strong cold front then sweeping through the area during the evening. This resulted in several rounds of severe weather across the region.|

|Brief Description: Tornado touched down in field along the Atkinson-Coffee County line near Marshal Corbet Road. Just inside of Coffee county one wood frame structure had a portion of its roof removed. Three large 100 yard long chicken houses were totally destroyed and machinery tossed about. One automobile was picked up and landed on the roof of a brick structure. Extensive roof damage to brick structure. Several work sheds destroyed. Trees snapped off and twisted at tops with debris wrapped in tree tops. Numerous large live oak trees felled. Clear evidence of rotation was noted by investigating officials. The storm continued north in a discontinuous path doing damage to cotton fields. the tornado crossed Highway 135 at the Satilla River with trees again snapped and twisted at the tops. Approximately 1 mile north of the Satilla River the tornado passed over an airstrip destroying a hanger/office structure and severely damaging a crop dusting aircraft. Debris from the destroyed chicken houses was identified at this site some 3 miles from its point of origin. This was the final discernable touchdown, although there was some evidence from debris further north that the system continued as a funnel cloud just above tree top level into southeast Douglas.|

|Brief Description: EVENT NARRATIVE: The United States Army Garrison at Fort Steward, Georgia found 850 full size trees downed in one of their training areas. Crew members of Fort Steward determined many downed trees were in a dropped matchstick pattern. A survey from air and ground confirmed EF2 tornado damage with estimated wind speeds between 115 to 125 miles per hour. The tornado occurred along a southwest to northeast path beginning at latitude and longitude coordinates 32.002, -81.708 and ending at 32.013, -81.708. The tornado path length was 0.80 mile long and approximately 1/4 mile to 1/2 mile wide. A total of 63 acres were damaged. The monetary damage was estimated at $425,000. Timber from the trees will be salvaged. No injuries or deaths resulted from this event. EPISODE NARRATIVE: A weak short wave tracked northeast to the lee of the Southern Appalachians late Tuesday afternoon into Tuesday evening, providing ascent and allowing a band of convection to shift east into the forecast area. Convection became enhanced as a warm front lifted north and west into the forecast area causing dewpoints to surge into the mid 70s and destabilization to occur. Meanwhile, strong low-level shear developed as a low-level jet strengthened to 30-50 kt over the area.|
