From NWS Birmingham: The tornado first touched down near the Walnut Grove community along the Blount-Etowah County line. Here sporadic tree damage was noted with some large limbs snapped and trees uprooted along Highway 278. The tornado tracked northeast tracking along the ridgeline in northern Etowah County. Sporadic tree damage was noted along Cove Spring Road and Cove Road. The tornado began to strengthen as it moved northeast toward the southern portions of Boaz. Several homes were damaged in this area some from falling trees and others from direct tornado damage. At least one home near the intersection of Highway 179 and Glover Road sustained significant structural damage. A large industrial building in this area also sustained significant damage. At this point, the tornado reached its maximum intensity in Etowah County at 115 mph with a width of approximately 350 yards. The tornado continued to move northeast through Boaz with homes and structures damaged along Pleasant Hill Road and Highway 205. Significant tree damage with uprooted and snapped trees were noted in this area. The tornado continued to track northeast through the city of Boaz and into Marshall County.
From NWS Huntsville: The tornado in Marshall County likely touched down west of HWY 431, south of Denson Ave. It quickly intensified to its peak strength as it crossed HWY 431 and plowed through a neighborhood north of Roden Rd. Nearly every single home (dozens) in this neighborhood experienced some degree of damage. The most intense damage was noted from two separate single family homes. The first home, with most devastating damage, was completely destroyed and was mostly taken off its foundation with only two small interior rooms remaining, where the residents took shelter. It was noted howeverthat the anchorage system for the home appeared to be non- existent with no bolts observed to the foundation crawl space piers. This led to a much lower expected value for storm damage of this magnitude. The second heavily damaged home had damage indicators more in line with a strong EF2 tornado. This home, also on Lee Ave, experienced a collapse of exterior walls, likely occurring after the roof was taken off.
The tornado continued on an east to northeast track across and along Bethsaida Rd causing numerous trees to snap or be uprooted. Several houses appeared to have had shingle roof damage. The tornado continued in the southern DeKalb County and caused sporadic tree damage before it dissipated near the intersection of CR 29 and CR 26.
