| Brief Description: EVENT NARRATIVE: This extremely large tornado (1.8 miles wide) moved east and then turned northeast towards Kiowa county. Many power poles were taken down by the tornado. It also caused EF3 damage to trees, two old houses, barns and it carried an oil tank battery 1.8 miles depositing it in trees. There was at least 20 head of cattle killed by the tornado. There was minor injuries received by a 20 year old male as he took refuge in his truck that was parked next to a baler inside a barn. The barn was completely swept away leaving the young man with cuts from broken glass. The baler that was left standing probably protected him and his truck from going airborne, if not rolling. Also, there was serious injury to a male in a semi on highway 34 in the vicinity of 37.3327 N, 99.6344 W probably by the RFD. Two other semis parked at this location rolled over but no injuries were sustained by the drivers. This extremely large tornado moved into Kiowa county. The radar signature was eerily similar to the Greensburg tornado that occurred on May 4, 2007. EPISODE NARRATIVE: An anonymously strong upper level system allowed everything to come together at the surface to produced what is perhaps the biggest tornado outbreak to ever occur in the Dodge City CWA! Fifty-five tornadoes were documented during that afternoon and evening! Some of the tornadoes were very large and damaging. The character of the supercell thunderstorms that day had similarities to the storms that produced the Greensburg tornado a little over a year after. In fact there was one tornado that was just as large and perhaps could have been just as damaging that was headed towards the small Kiowa county town but fortunately turned and dissipated. | |||||||||||

| Brief Description: EVENT NARRATIVE: This killer tornado started in Comanche county and crossed into Kiowa county at 2003 CST / 2103 CDT. It curved north then northwest before making a complete loop northwest of Greensburg. Thus, the path was 25.8 miles. This tornado destroyed nearly 95 percent of the town of Greensburg and despite adequate warning, unfortunately took the life of 11 people, some that were in basements. First responders arriving on the scene requested three refrigerated refer trucks thinking there would be hundreds of fatalities. It also destroyed a dozen homes and a church south of Greensburg but did not cause injury. In all, 961 homes and businesses were destroyed, 216 received major damage and 307 received minor damage. As the tornado was dissipating it turned northwest, west, south and then back east making a loop. This was documented on both high resolution doppler radar and through the ground survey. Also as the tornado was dissipating a new circulation quickly grew northeast of town. Several oil storage tanks were destroyed causing an environmental concern. In the town of Greensburg, hazardous material was strewn everywhere. As of July 26th, the debris was still not fully cleaned up. Two landfills were filled with debris from the town and this was even as most was burned. Hundreds of thousands of dump truck loads were taken out. It was estimated that approximately 400,000 cubic yards of debris was removed. The major highway running through town was closed for 1 full month. At one time there were over 150 law enforcement officers (from all over the country) present. Military was called in for debris removal and rebuilding. Damage of insured losses exceeded $150 million, but including un-insured losses, was roughly 250 million dollars. **** NOTE **** The 11th victim passed away on September 19th, 2007 after a long battle with a head injury sustained during the tornado. EPISODE NARRATIVE: A destructive tornado, the first 5 rating on the new Enhanced-Fujita Scale and the first 5 classification since May 3, 1999 when an F5 tornado ripped through Moore, Oklahoma occurred on this day. There were 12 tornadoes during about a 4 hour period, one a little over 2 miles wide! Two of the tornadoes existed for over 1 hour as they churned up the ground, leveling homes and causing fatalities along their path. Miraculously, on 13 people perished, 11 in Greensburg - a miracle because over 90 percent of the town of Greensburg was literately wiped off the face of the earth. Another round of tornadoes occurred the following day across generally the same area. Nearly 250 pivot irrigation sprinklers were damaged or destroyed during the 2 day outbreak. Due to the number of sprinklers involved and the lack of replacements, some farmers would be out of service for over 1 year. | |||||||||||

| Brief Description: This tornado became quite large as it moved at first to the southwest and then turned southeast. The tornado completely stripped topsoil from one field and debarked trees at a pond. Several dozen cattle were killed with several 1500 pound heifers carried 3/4 of a mile. Two other tornadoes crossed nearly the same location within an hour, which may have contributed to the scouring of the topsoil. | |||||||||||

| Brief Description: A tornado touched down 3.5 WSW of Kismet at 1535 CST and moved ENE across Highway 54 and east into Meade County where it ended at 1610 CST at a point one southeast of Meade. Speed of movement was 35 mph with total path length of 26 miles. In Seward County the tornado struck a car and mobile home 2 E of Kismet at 1540 CST. Two adults were in the car and one adult and five children were in the mobile home. All eight sustained minor injuries and the mobile home was demolished. The tornado had a maximum path width of 1,000 yards in Seward County, but expanded to a maximum width of a mile southeast of Plains in Meade County. | |||||||||||

| Brief Description: EVENT NARRATIVE: A strong tornado, rated EF3 at its peak intensity, struck south-southwest of the Selman area, producing widespread damage along its path. The tornado touched down, doing minor damage to trees and outbuildings. The tornado continued moving northeast and struck a residence. Significant damage consistent with EF2 damage was seen at this location. More significant damage was done to a residence and stocked workshop building as the tornado moved northeast. This was the strongest point of the tornado, rated EF3. A semi-cab and a 20-horse trailer were blown 50 yards from inside of the workshop. They both sustained significant damage. The tornado moved north from this point, doing EF2 damage to a building and workshop. The owners of the home took shelter in their storm shelter during the tornado, but became trapped inside by debris over top of the door. They were freed by local firemen after approximately 45 minutes. The tornado continued north and then northwest as it began to dissipate. Before it dissipated, however, a heavy fiberglass water tank that was filled with water was destroyed and moved some distance away. Two horses were also killed and one was seriously injured by swirling tin and other sharp debris. Monetary damages were estimated. EPISODE NARRATIVE: Thunderstorms developed during the afternoon ahead of a dry line that was located near the Texas panhandle and Oklahoma border. The thunderstorms quickly became supercells as they moved toward southwest Kansas. Very large hail was the initial threat, although a significant tornado threat became apparent as they neared the Kansas border. Three tornadoes were reported with the thunderstorms, with two of them doing significant damage. The tornadic thunderstorms moved northeast by nightfall, with other less severe thunderstorms developing farther south. Monetary damages were estimated. | |||||||||||

| Brief Description: EVENT NARRATIVE: This 1/2 mile wide tornado moved out of Oklahoma. EF3+ damaged was based on trees that appeared to be sand blasted. Also, there were trees uprooted, several antique cars that have yet to be found as of late July, 2008 (probably dropped in ravines in the area). An oil tank was carried 2 miles. Several head of cattle were killed. The tornado turned west (left) as it began to dissipate.

| Brief Description: EVENT NARRATIVE: The tornado began just south of the Bar-B Ranch and moved north damaging much of the ranch property...mainly along the western edge. A large horse trailer and several other utility trailers were destroyed as they bounced and rolled and/or became airborne for significant distances. The horse trailer was displaced more than one hundred and fifty yards from its original location. Several power poles and trees were snapped at the base within the path of the tornado. A large grain silo was toppled with parts of the roof of the silo carried over one hundred yards. No injuries were reported. EPISODE NARRATIVE: Severe thunderstorms during the early evening hours produced deadly tornadoes...damaging winds and hail across the central and eastern Oklahoma panhandle. Heavy rains caused flash flooding in the eastern Oklahoma panhandle during the late night and early morning hours. A couple was killed in Beaver County when a tornado struck their home. | |||||||||||
