On May 30th, the NHC began monitoring an area of disturbed weather over the Gulf of Mexico for possible tropical development. An area of low pressure developed the following day, and the disturbance was designated Invest 91 L. The system organized into Tropical Depression Two at 21 UTC on June 1st, while located off the west coast of South Florida. Hurricane Hunters investigated the depression on the morning of June 2nd, and determined that it had strengthened into Tropical Storm Arlene. Wind shear and a dry atmosphere prevented the system from intensifying further as it drifted southward through the Gulf of Mexico. On June 3rd at 15 UTC, Arlene weakened to a tropical depression, and degenerated into a remnant low shortly thereafter.
