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: EVENT NARRATIVE: This strong tornado touched down in the Blackwater Community and caused extensive damage along its 2 mile path. Six homes were destroyed, five of which were mobile homes and one modular home. Nine people were injured with three serious. One car was flipped over and rolled along with extensive damage to trees and power lines along the path of this high end F2 tornado. EPISODE NARRATIVE: During the evening of Jan 4th and early morning hours of Jan 5th, a potent storm system moved across the Lower Mississippi Valley. This system was dynamic enough to generate a line of thunderstorms across Central Mississippi. This line developed within a strongly sheared environment and evolved into a squall line with bowing segments. These bowing segments proved very efficient with respect to producing damaging wind gusts and six tornadoes. The squall line matured just east of Interstate 55 around 11 pm and raced east before exiting into Alabama around 3 am. | |||||||||||
