1940: A Category 2 hurricane struck the Georgia and South Carolina coast. A 13-foot storm tide was measured along the South Carolina coast, while over 15 inches of rain fell across northern North Carolina. Significant flooding and landslides struck Georgia, North Carolina, Tennessee, and Virginia during the system's slow trek as a weakening tropical storm, and then as an extratropical cyclone, through the Southeast. The landslides which struck North Carolina were considered a once in a century event. Damages relating to the storm totaled $13 million (1940 USD) and 50 people perished.
