Earl developed from a tropical wave that moved off the coast of Africa on September 18. Over the next several days, the wave traversed westward across the Atlantic Ocean at low latitudes, producing disorganized convection. As the wave approached the Lesser Antilles, it began to interact with a large and powerful upper-level trough that was at least partially caused by the outflow of Tropical Storm Danielle and Hurricane Bonnie. Due to interaction with the aforementioned trough, most of the wave's convection was located north of the wave axis. The trough developed into an upper-level low while moving southwestward toward central Cuba. It is estimated that the wave developed into Tropical Depression Eight at 1800 UTC September 26 while located about 360 miles north of Hispaniola. The depression moved quickly west-northwest toward the northern Bahamas, steered by the aforementioned upper-level low over Cuba. An approaching cold front caused the depression to stall over the warm Gulf Stream, where it strengthened, becoming Tropical Storm Earl at 1200 UTC September 29, as per reconnaissance reports as well as ship observations. By the time it had become a tropical storm, Earl was already moving eastward ahead of the aforementioned cold front. Nevertheless, Earl was able to remain a distinct, separate entity from the cold front, and it reached its peak intensity of 65 mph with a pressure of 990 mb at 0000 UTC October 2. Earl continued moving east-southeast, producing transient convection, but maintaining a well-defined low-level circulation. At 1200 UTC October 3, Earl weakened to a tropical depression, and it became an extratropical cyclone later that day. Earl's extratropical remnants wandered across the Atlantic Ocean for a few more days before dissipating completely.
Lack of Retirement
Because it did not affect land, the name Earl was not retired in the Spring of 1993 by the World Meteorological Organization. It has been used in both the 1998 season as well as the 2004 season, and will be used again in 2010.
