Tropical Storm Doria was the costliest tropical cyclone in the 1971 Atlantic hurricane season. The fifth tropical storm of the season, Doria developed from a tropical wave on August 20 to the east of the Lesser Antilles, and after five days without development it attained tropical storm status to the east of Florida. Doria turned to the north, and reached peak winds of 65 mph (105 km/h) as it was making landfall near Morehead City, North Carolina. It turned to the northeast, and moved through the Mid-Atlantic and New England as a tropical storm before becoming an extratropical storm over Maine on August 29.
