What was the name of the first tropical storm of 2015 whose season began in June?
Tropical Storm Ana (2015) Tropical Storm Ana was the earliest recorded tropical cyclone to make landfall in the United States in any given year. A relatively rare pre-season system, Ana was the first tropical storm of the 2015 Atlantic hurricane season. It developed as a subtropical cyclone from a non-tropical low north of the Bahamas, and intensified to attain peak winds of 60 mph before transitioning into a fully tropical cyclone early on May 9. Sustained in part by the warm waters of the Gulf Stream, Ana made landfall along the northeast coast of South Carolina early the next morning, becoming the earliest U.S. landfalling system on record. Overall, damage from the storm was minor. Heavy rainfall and gusty winds affected parts of the Carolinas, and some vulnerable beaches endured coastal flooding and several feet of erosion. Gusty winds damaged trees and powerlines, causing sporadic power outages, and a weak tornado was reported in association with Ana. In North Carolina, two deaths—one direct and one indirect—were attributed to the storm.
Hurricane Irene–Olivia Hurricane Irene–Olivia was the first actively tracked tropical cyclone to move into the eastern Pacific Ocean from the Atlantic basin. It originated as a tropical depression on September 11, 1971, in the tropical Atlantic. The cyclone tracked nearly due westward at a low latitude, passing through the southern Windward Islands and later over northern South America. In the southwest Caribbean Sea, it intensified to a tropical storm and later a hurricane. Irene made landfall on southeastern Nicaragua on September 19, and maintained its circulation as it crossed the low-lying terrain of the country. Restrengthening after reaching the Pacific, Irene was renamed Hurricane Olivia, which ultimately attained peak winds of 115 mph (185 km/h). Olivia weakened significantly before moving ashore on the Baja California Peninsula on September 30; the next day it dissipated.
