What was the name of the first tropical storm of 2015 whose season began in June?
Timeline of the 2015 Atlantic hurricane season The 2015 Atlantic hurricane season was the third consecutive year to feature below-average activity, with eleven named storms. The season began on June 1 and ended on November 30, dates adopted by convention that historically describe the period in each year when most tropical cyclones form in the Atlantic basin. The season's first storm, Tropical Storm Ana, developed on May 8; the season's final storm, Hurricane Kate, lost its tropical characteristics on November 11.
2011 Atlantic hurricane season The 2011 Atlantic hurricane season is tied with 1887, 1995, 2010, and the following 2012 season for the third highest number of named storms since record-keeping began in 1851. The season officially began on June 1 and ended on November 30, dates which conventionally delimit the period during each year in which most tropical cyclones develop in the Atlantic Ocean. However, the first tropical storm of the season, Arlene, did not develop until nearly a month later. The final system, Tropical Storm Sean, dissipated over the open Atlantic on November 11. Despite unfavorable conditions, seven storms reached Category 1 strength and four of those storms reached major hurricane status, which is Category 3 or higher on the Saffir–Simpson scale. Katia and Ophelia reached Category 4 status and tied with strongest winds, though Ophelia was the most intense cyclone of the season because it had a lower barometric pressure.
