. As the tornado traversed through the counties
Charles,
Calvert,
Dorchester and
Wicomico, many forest and towns were left in ruins. In La Plata, the structural damage was catastrophic. Approximately 65 percent of the entire downtown sustained heavy damage or complete destruction. In total, the tornado killed 5 people and injured some 122 others. It also inflicted $115 million in damage, making it the costliest Mid-Atlantic tornado on record. Entire
utility poles were also snapped and thrown. Along Saint Marys Avenue, a brick and steel
lumber yard building was demolished. "Heavy F4 damage" occurred just east of this. As the tornado entered Calvert County south of the
Patuxent River Bridge, it struck a development of homes. Over half of them were damaged. Several homes were also destroyed. Along
Hallowing Point Road, a home with no anchoring or foundation was picked up and thrown into a culvert, killing an elderly couple. Many other homes also lost their walls and roofs in western Calvert County. The tornado continued south of
Prince Frederick before passing just north of the
Calvert Cliffs Nuclear Power Plant where several large trees were leveled. Tornado damage in Calvert was rated at F1 to F2 intensity. At least 125 homes were damaged, with another 10 being destroyed. Many of the "slider homes" swept off their foundation were rated F1 to F3, with surveyors having to rely solely on the severity of the surrounding damage to determine ratings. == Aftermath ==
