The remnants of Cyclone Dawson (South Atlantic) entered the equator on April 29. Reforming into a strong tropical low on April 30, NHC intiated watch on this system. Although poor organization and minimal thunderstorms, NHC upgraded the low into Tropical Depression One on May 1, the earliest storm to form in a season since 2003. Struggling to intensify, One wasn't designated a Tropical Storm until it was in the Yucatan Channel on May 5.
