Hurricane Diana was the first tropical cyclone to produce hurricane-force winds at a nuclear power plant. The ninth tropical cyclone, fourth named storm, first hurricane, and first major hurricane of the 1984 Atlantic hurricane season, Diana developed just north of the Bahamas on September 8 from an extratropical cyclone. After initially moving westward towards east-central Florida, the storm turned northward and paralleled the coastline. Diana intensified into a hurricane on September 11 and continued to strengthen, peaking as a Category 4 hurricane on the Saffir–Simpson scale with maximum sustained winds of 130 mph (215 km/h) on the following day. After drifting offshore the Carolinas, Diana weakened and then made landfall near Cape Fear, North Carolina, as a Category 2 hurricane on September 13. The cyclone quickly weakened to a tropical storm and curved back out to sea, heading northeast until it became extratropical near Newfoundland on September 16. Category 4 hurricane: peak winds of 130 mph (115 knots), lowest pressure 949 mb. September 8 – September 16, 1984. Landfall: September 13 at 90 mph, 33.9°N 78.0°W. Accumulated cyclone energy: 15.2.
