EF3 tornado in Marshall County, Alabama

A tornado touched down approximately 2.5 miles south southeast of Grant along Campbell Mill Road. A few houses sustained minor roof damage on the southeast side of Grant. At least two mobile homes sustained major damage from falling trees. The tornado continued east crossing Old Union Road, Columbus City Road, and Cardessa Lane before descending into the Tennessee River Valley. The tornado crossed Highway 79 at approximately 307 PM CDT at the Baker Mountain Road intersection. At this point the damage path width was just below a half of a mile wide. One woman was injured when a tree fell on her car near the Waterfront Grocery store. Several houses sustained substantial damage on the east side of Highway 79 and many trees were snapped and uprooted. The roof was blown off of one home and a brick wall collapsed. The tornado crossed a small inlet onto the south side of Preston Island, wiping out several boat docks and boat houses. Several homes sustained significant damage on the island from falling trees. At least two wood homes had complete roof collapse and partial wall collapse.

The tornado crossed Lake Guntersville into the South Sauty community. At least one person was injured in this area when he was caught outside during the tornado. At this point, the damage path width increased to at least a half a mile wide. Several well built homes were damaged by falling trees along Memonminee Road. At least 20 boat houses were destroyed in the community. Along Chilcotin Road a well constructed two story brick house lost its roof. Also falling trees damaged several camper trailers. One trailer was blown into Lake Guntersville. Thousands of trees were uprooted or snapped along the path of the tornado in Marshall county. The tornado crossed the CR 67 causeway and very shortly after moved into Jackson county. On CR 67, tornadic winds damaged the shoulder of the roadway as it crossed.

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.
