| Brief Description: EVENT NARRATIVE: The tornado moved from Marion County, north-northeast of Rea Valley, into Baxter County, just east-southeast of Cotter. A survey by the Red Cross indicated 21 houses were destroyed, 23 suffered major damage, 35 had minor damage, and 147 others were affected. In addition, 9 mobile homes were destroyed, 12 suffered major damage, 10 had minor damage, and 10 others were affected. One fatality occurred in a mobile home park. Most of the residential structures were in the area around Gassville. A number of businesses in Gassville, along U.S. Highway 62/412, were damaged. Numerous trees, power lines, and power poles were blown down. The tornado dissipated before reaching Mountain Home. EPISODE NARRATIVE: Early on the 5th, a strong storm system approached from the Plains. Ahead of the system, breezy southerly winds provided well above normal temperatures and abundant moisture. Warmth and moisture destabilized the atmosphere and fueled developing thunderstorms. A cold front moved across the state causing numerous severe storms and several tornadoes. One of the tornadoes tracked from Yell County to Sharp County, staying on the ground for 121.84 miles. This track length set a record for the longest tornado path ever recorded in Arkansas. The continuous track was confirmed by two National Weather Service meteorologists who flew the track with the Civil Air Patrol. The final track was based on ground surveys, the Civil Air Patrol flight, and an aerial mapping flight performed for the Arkansas Forestry Commission. | |||||||||||

| Brief Description: A tornado touched down just before 830 pm just south of Highway 76/86 between Exeter and Ridgley. Initial damage was limited to chicken houses and grain bins which suffered sporadic damage. The tornado quickly intensified as it crossed the Highway and moved north across a residence. Extensive damage occurred to the property including two storage buildings swept clean of their foundations, a dump truck flipped almost 30 feet, and the loss of the residence's roof. Nearly a dozen other vehicles suffered collateral damage, along with numerous trees stripped or uprooted. Three individuals were injured as their vehicle was flipped over. The tornado tracked for approximately four miles north of Exeter, causing significant damage to at least three additional residences. Numerous outbuildings were also destroyed along with hundreds of trees that were uprooted. The tornado reached a width of over one quarter of a mile at peak intensity, before dissipating just north of Highway CC. The damage assessment would place this tornado at the high end of an F2 rating on the fujita scale...with winds approaching 150 mph. | |||||||||||
