The supercell then spawned a series of destructive tornadoes while crossing the Potomac River into Maryland, that moved along a nearly continual path starting south of Indian Head, Maryland and continuing into La Plata, Maryland, devastating La Plata's business district. Multiple homes were reduced to bare slabs by the La Plata tornado, and the damage was unintentionally rated as an F5. Further surveys revealed that the homes that were swept away were not attached to their foundations, and the tornado was then downgraded to an F4. Very large hail was also reported with these storms. Much of La Plata had previously been decimated by an F4 tornado on November 9, 1926.
