Task: Explanation
Input (English): 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. Question: What was the name of the first tropical storm of 2015 whose season began in June? Answer: Tropical Storm Ana
Output (English):  A relatively rare preseason system, Ana was the first tropical storm of the 2015 Atlantic hurricane season.
