| Brief Description: EVENT NARRATIVE: A significant tornado first touched down around 1227 pm at State Highway 28 near Miller's Ferry dam. The tornado then tracked northeast across William Bill Dannelly Reservoir moving ashore on Sand Island Drive. This is where most of the severe damage occurred with numerous homes damaged or destroyed. One resident had arrived at his home on the lake to eat lunch when the tornado hit and he was killed when his newer model manufactured home was destroyed. The straps holding the home down all snapped in the same place. He was thrown out of his home and later found in the debris. Neighbors next door had sought shelter in an underground storm shelter outside their house seconds before the tornado hit. When they safely emerged from the shelter, they found their home destroyed. Most of the homes on Sand Island are vacation homes with part-time residents. If the tornado had struck on the weekend when more people are present, the loss of life would likely have been greater. Around 40 homes(four of these were slab homes)were damaged or destroyed along Sand Island Drive with some of the debris scattered up to two miles downstream. The tornado continued quickly to the northeast through sparsely populated areas. Damage did occur to homes and hunting camps along this path. However, the damage here was only rated as EF-0 and EF-1 on the Enhanced Fujita Scale. The tornado crossed into Dallas County. In all, one person died and two people were slightly injured by the tornado. The injuries occurred along Sand Island Drive when a single wide trailer was destroyed with the occupants being thrown from the trailer. They were protected from flying debris by part of the trailer that had fallen on top of them. The highest wind speed of the tornado was estimated at 185 mph. EPISODE NARRATIVE: Isolated thunderstorms developed ahead of a strong spring cold front. One of these thunderstorms produced a significant tornado in Wilcox County. | |||||||||||

| Brief Description: The tornado began in southwestern Tuscaloosa County on the west side of the Black Warrior River. Traveling in a northeasterly direction the tornado moved from a rural, unpopulated area of the Black Warrior River into an area of homes south of Shelton State Community College. The tornado crossed SR 69 destroying a nearly complete shopping center which included a Winn Dixie store. East of SR 69 the tornado destroyed a number of houses and residential structures. As the tornado reached US 82 it destroyed a number of mobile homes where several deaths were reported. From US 82 the tornado continued northeasterly downing numerous trees and power lines and damaging residential structures. The tornado crossed I-20/59 just west of exit 77 where many trees were uprooted or snapped off. Minor damage occurred to the JVC manufacturing facility. At exit 77 a number of commercial structures including hotels, fast food restaurants, and truck stops sustained damage including a number of vehicles that were overturned. The tornado continued northeasterly for a couple of miles before dissipating rapidly. Ironically, the tornado dissipated as it moved into an open, unpopulated area. The tornado was spawned by a supercell thunderstorm that originated in Mississippi. This thunderstorm was responsible for additional tornado damage in St. Clair and Etowah counties. Tuscaloosa EMA reported 11 fatalities with this tornado along with 144 injuries. Nine of the fatalities occurred in mobile homes, one in a vehicle, and one in a commercial building converted to residential use. Six of those killed were females and five were males.

There were 251 single family dwellings affected (43 destroyed, 76 with major damage, 138 with minor damage), 179 mobile homes affected (79 destroyed, 23 with major damage, 77 with minor damage), and 13 businesses affected (1 destroyed, 7 with major damage, 5 with minor damage). The tornado was on the ground for a total of 18 miles, all within Tuscaloosa County. The tornado path was estimated to be 750 yards wide at it's maximum intensity. This tornado was rated an F4 on the Fujita Scale for tornado intensity. Tornado intensity varied along the path with considerable F2 and F3 damage in the area from just west of SR 69 to US 82 in the Hinton Place and Hillcrest Meadows areas as well as the Bear Creek area.
