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.
Cyclone Roanu Cyclonic Storm Roanu was a relatively weak tropical cyclone that caused severe flooding in Sri Lanka and Bangladesh during May 2016. It is the first tropical cyclone of the annual cyclone season. Roanu originated from a low pressure area that formed south of Sri Lanka, which gradually drifted north and intensified into a cyclonic storm on 19 May. However, wind shear and land interaction caused it to weaken slightly, before reintensifying as it accelerated towards the coast of Bangladesh.
