| Brief Description: Initial touchdown occurred 1 mile southwest of Hoisington. The tornado rapidly achieved F3 intensity as it entered the west side of town. Moving northeast around 20 mph, the tornado intensified to F4 within 2-3 minutes. While crossing northwest Hoisington, the tornado inflicted a path about 2 miles long and about 2 blocks wide of almost complete destruction. Damage summary: 182 homes destroyed, 52 homes with major damage, 180 homes with minor to moderate damage, 12 businesses destroyed, tore the roof off the hospital, and severed power to most (if not all) areas on the northwest and north sides of town. As the tornado exited through the north side of town it weakened rapidly, inflicting F1-F2 damage as it approached Deception Creek which runs in a southeast to northwest manner 3 miles northeast of town. Once the tornado crossed the creek, it suddenly turned toward the northwest where it damaged two farmsteads shortly before dissipating. One man, 69 years of age, was killed when a minivan fell on him. There were 28 injuries of which 3 were critical. M69PH | |||||||||||

| Brief Description: EVENT NARRATIVE: This wedge tornado was occurring simultaneously to another large but smaller tornado (within several miles). Damage was done to houses, trees and pivot irrigation sprinklers. EPISODE NARRATIVE: Unbelievably, an outbreak of tornadoes, some very large in size, raked the earth in basically the same area as the day before when Greensburg was nearly completely leveled. Although some of the tornadoes were large and apparently very strong, there was no loss of life on this day. A National Weather Service assessment team was in an area about 30 minutes before a tornado moved through. They also saw one tornado during the storm survey of damage that was produced the day before. | |||||||||||

| Brief Description: EVENT NARRATIVE: This killer tornado formed just east of another large but dissipating tornado that was approaching Macksville. Unfortunately a law officer watching the dissipating tornado was unaware that this one was rapidly forming and could not get out of harms way. His car was thrown at least 1/4 of a mile and was found in a field. He died several days later from catastrophic injuries received in the crushed vehicle. EF3 damage was done to over a dozen farms, trees, machinery, vehicles, pivot irrigation sprinklers and power poles. 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: EVENT NARRATIVE: This tornado moved out of Stafford county and did EF2 damage to a house and barn just west of the Stafford/Edwards county line. A Female received a serious injury when she was blown down the stairs. Pivot sprinklers and trees received EF1-2 damage. The tornado started in the southeast part of Edwards county, moved into Pratt and Stafford and then turned northwest before ending in the extreme northeast part of the county. 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. | |||||||||||

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: EVENT NARRATIVE: This large tornado moved out of Pratt county and did EF3 damage before moving into Edwards county. EF3 damage was done to trees and a pivot sprinkler. Other pivot sprinklers received EF1-2 damage along with EF2 damage done to a house and grain bins. 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. | |||||||||||
