The ninth tropical depression of the Atlantic Ocean hurricane season developed in the central Atlantic on September 16, 2015. The day before, NASA's RapidScat instrument analyzed the surface winds of the developing low pressure area and found tropical-storm-force winds in one quadrant of the system. NASA's Aqua satellite looked at the depression and saw that it was already being affected by wind shear.
