Tropical Storm Dolly was the fourth named storm of the 2002 Atlantic hurricane season. Dolly formed on August 29 in the deep tropics from a tropical wave that emerged off the coast of Africa on August 27. Dolly moved west, then northwest and dissipated on September 2 because of strong upper-level wind shear. Dolly was one only two tropical cyclones to develop within the deep tropics during 2002; the other being Hurricane Lili. Dolly was initially forecast to become a hurricane, but it failed to do this. Operationally, Dolly was considered to have had 65 mph winds, but post-season analysis indicated that Dolly had 60 mph winds at its peak.

Dolly caused no damage and no deaths.

Meteorological History

A tropical wave moved off the coast of Africa on August 27. The wave moved westward across the Atlantic Ocean, and ship reports indicated that the wave was accompanied by an area of low pressure. In addition, satellite imagery showed an increase in convection. The wave moved west, then west-southwest and by 1200 UTC on August 29, the wave had organized enough for the National Hurricane Center to classify it as Tropical Depression Four while located about 550 miles southwest of the westernmost Cape Verde Islands. The depression quickly became better organized, developing a well-defined cyclonically curved convective bands as well as good outflow in all quadrants. By 1800 UTC that same day, the depression strengthened into Tropical Storm Dolly. It reached its peak intensity of 60 mph with a pressure of 997 mb 1200 UTC on August 30. Dolly then moved to west-northwest around the periphery of a subtropical ridge for the next couple of days. Thereafter, Dolly curved to the northwest and then north ahead of an approaching mid-level trough with a minor fluctuation in intensity at 0000 UTC on September 3 when Dolly's convection decreased. Dolly became a remnant low late on September 4 when strong upper-level winds removed most of the deep convection. Dolly eventually became absorbed by the aforementioned trough.

Lack of Retirement

Because it affected no land areas, the name Dolly was not retired in the Spring of 2003 by the World Meteorological Organization. It is on the list of names to be used for the 2008 Atlantic hurricane season.
