| Brief Description: An F2 tornado that developed over Franklin County, moved into Johnson County about 3 miles west-southwest of Hunt, on Highway 352. The tornado moved northeastward, passing just northwest of Hunt. The tornado continued on across a portion of Horsehead Lake, tracked several miles east of Catalpa and then crossed into Newton County about one mile west of Salus.

Two additional injuries occurred on County Road 29, about 1.5 miles north of Hunt, when two people were inside a chicken house when it was destroyed. Six chicken houses were destroyed at this location. Three of the chicken houses contained about 120 thousand chickens, many of which were killed. Other damage in Johnson County included more than a dozen barns destroyed, several mobile homes destroyed, several homes with major damage and a number of homes with lesser damage. A number of vehicles were destroyed and many others were damaged. Many outbuildings were destroyed and thousands of trees were blown down. | |||||||||||

| 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 strong tornado was spawned in southern Johnson County. Toward the town of Hartman, the tornado heavily damaged or destroyed a couple of barns. Farther northeast toward Clarksville, every piece of tin was removed from a chicken house. Chickens were thrown from the house and from nearby houses. Up to 10,000 chickens were lost in the storm. Numerous trees were also downed. The tornado tracked about 7 miles before dissipating just southwest of Clarksville | |||||||||||

| Brief Description: EVENT NARRATIVE: This tornado exited Conway County north of Cleveland and entered Van Buren County south-southeast of Liberty Springs. The tornado, rated EF3 in Van Buren County, caused extensive damage to the town of Scotland, especially in areas along Lo Gap Road. A 67 year-old woman was killed when she was thrown from her home. Approximately 15 others were injured. A damage assessment by the Arkansas Department of Emergency Management indicated 13 homes (including houses and mobile homes) destroyed, 3 homes with major damage, 7 homes with minor damage, and 11 homes affected. In addition, Scotland's community center was destroyed, and barns, outbuildings, and a gas well were damaged. Thousands of trees and numerous power lines were blown down. EPISODE NARRATIVE: Moisture from the Gulf of Mexico surged into Arkansas at the end of April, so conditions in the state became warm and humid. On the 30th, a strong area of low pressure aloft approached from the west, resulting in the development of thunderstorms. Wind shear, a change in wind direction and speed with height, was present. This created a favorable environment for the formation of tornadoes. | |||||||||||
