Hurricane Diane made landfall near Wilmington, North Carolina, and it went on to cause major floods and kill more than 184 people.

Hurricane Diane was the first Atlantic hurricane to cause more than an estimated $1 billion in damage, including direct costs and the loss of business and personal revenue. It formed on August 7 from a tropical wave between the Lesser Antilles and Cape Verde. Diane initially moved west-northwestward with little change in its intensity, but began to strengthen rapidly after turning to the north-northeast. On August 12, the hurricane reached peak sustained winds of 105 mph (165 km/h), making it a Category 2 hurricane. Gradually weakening after veering back west, Diane made landfall near Wilmington, North Carolina, as a strong tropical storm on August 17, just five days after Hurricane Connie struck near the same area. Diane weakened further after moving inland, at which point the United States Weather Bureau noted a decreased threat of further destruction. The storm turned to the northeast, and warm waters from the Atlantic Ocean helped produce record rainfall across the northeastern United States. On August 19, Diane emerged into the Atlantic Ocean southeast of New York City, becoming extratropical two days later and completely dissipating by August 23.
