EF3 tornado in Dekalb County, Alabama

This destructive tornado continued to move east northeast from Jackson county into Dekalb county. Just on the east side of Highway 35, a large metal industrial building that was securely anchored into the ground was completely destroyed. In Sylvania, significant damage occurred to several homes in the Stonebrook division. One home was completely lifted off its foundation and driven nearly 4 feet into the ground. Sporadic damage continued just to the east of Sylvania until the tornado apparently lifted between 335 and 340 PM CDT, just south of the Mahan Crossroads community in west central Dekalb county.

A strong upper level storm moving across the Mississipi Valley brought a dry line and cold front into north Alabama during the afternoon and early evening hours. Several classic supercell thunderstorms developed by early afternoon in northwest Alabama, sweeping across the remainder of north Alabama during mid to late afternoon hours. Many of the storms produced very large hail, up to baseball and softball sized, producing significant damage, especially from Decatur through Madison and northwest Huntsville. One of the supercells produced a long track tornado producing damage of up to EF-3 intensity which struck northeastern Marshall County, crossed Lake Guntersville, and moved into southern DeKalb County.
