High Quality Content by WIKIPEDIA articles! Tropical Depression One was the first tropical cyclone to develop during the 2009 Atlantic hurricane season. Upon being declared a tropical depression on May 28, it marked the third time that a pre-season storm formed in three consecutive years. Originating from a disorganized area of low pressure off the coast of North Carolina, Tropical Depression One quickly developed over the Gulf stream. After attaining winds of 35 mph (55 km/h) along with a minimum pressure of 1006 mbar (hPa; 29.71 inHg), the depression began to weaken due to increasing wind shear and cooling sea surface temperatures. During the afternoon of May 29, convection associated with the system was significantly displaced from the center of circulation; this led the National Hurricane Center to issue their final advisory on the depression as it had degenerated into a remnant-low pressure area. As a tropical cyclone, Tropical Depression One had no effects on land; however, the precursor to the depression brought minor rainfall and light winds to parts of coastal North Carolina. Its track, formation, and timing were relatively similar to Tropical Storm One of the 1940 Atlantic hurricane season.
