The preliminary conclusion, based on the ground surveys, is that a single, continuous path of tornadic damage was produced from west of Tallulah Louisiana to the extreme western part of Oktibbeha county in northeast Mississippi. The tornado appeared to dissipate at this point but the storm produced two additional tornadoes in the NWS Jackson service area: an EF-1 in northern Oktibbeha County and an EF-2 in northeast Clay County. The main long track tornado was strong almost from its initial stage of development in northeast Louisiana. EF-2 and EF-3 damage was common all along the tornado's path into central Mississippi with areas of EF-4 damage observed in both Yazoo and Holmes counties. After crossing Interstate 55, the tornado weakened with EF-1 and occasional EF-2 damage being commom as the tornado moved across Attala County. The tornado reintensified as it moved into Choctaw County, with at least high end EF-3 damage occurring northwest of the Weir community. The tornado remained strong before rapidly weakening and then dissipating just after moving into Oktibbeha County. Event Summary A potent storm system brought an extended period of severe weather to the Arklamiss region beginning in the afternoon hours of Friday, April 23rd and lasting through the late evening hours of Saturday, April 24th. Scattered severe thunderstorms developed and moved across northeastern Louisiana and parts of Mississippi during the afternoon and evening hours. Several reports of large hail were received from across the area, including golf ball size hail in Sunflower County. In addition, some wind damage was reported over southern portions of Leflore County in association with a possible tornado. Though the storms on Friday did not cause widespread damage, a much more dangerous situation unfolded across the region on Saturday. Initially, two separate clusters of strong to severe thunderstorms affected the area during the morning hours. One moved across southeastern Arkansas and northwestern Mississippi, dropping hail up to golf ball size. Another moved across south central and southeastern Mississippi, producing large hail and some wind damage. One of the storms over southern Mississippi produced a possible tornado as it moved from southern Simpson County across Smith County, northern Jasper County, and into the Meridian area in Lauderdale County. The same storm produced golf ball size hail across Smith County. However, the most destructive storm of the day developed over northern Louisiana during the mid to late morning hours. The first report of damage was received shortly after 11am near the city of Tallulah. From that point, things only got worse as the supercell tracked from west to east across the entire state of Mississippi. Along the way, it produced significant damage in several locations including the Eagle Lake area of Warren County, Valley Park in Issaquena County, Satartia and Yazoo City in Yazoo County, Ebenezer and Durant in Holmes County, north of Kosciusko near Hesterville in Attala County, French Camp and Chester in Choctaw County, north of Starkville in Oktibbeha County, and east of West Point in Clay County. Multiple fatalities and injuries were reported in association with the storm, and several structures were damaged or destroyed. Later in the evening hours, additional storms lingered over portions of east central Mississippi. Large hail was reported with some of these storms, including hail to the size of tennis balls in southern Lowndes County. One storm northwest of Meridian produced an apparent tornado along the Lauderdale-Kemper County line. Several trees were downed and some minor structural damage was reported in the area. |
