Meteorological History


Erika developed from a tropical wave that exited the coast of Africa on September 2. On September 3, the wave passed over the Cape Verde Islands with deep convection confined to the southern portion of the wave axis. From September 4-6, the wave appeared on satellite imagery as mainly a very large swirl of low clouds. By September 7, convection began to increase, and by 1800 UTC September 8, the wave was well enough organized to designate the formation of a tropical depression while located midway between powerful Hurricane Claudette and Tropical Storm Danny. The cyclone moved around the western periphery of the subtropical ridge located north and later northeast. By 1800 UTC September 9, the depression strengthened into Tropical Storm Erika. Later on September 10, Erika briefly interacted with Hurricane Claudette and then accelerated northeastward along the norther portion of the aforementioned subtropical ridge. It is estimated that Erika reached its peak intensity of 60 mph at around 1800 UTC September 10 while heading toward the Azores. While approaching the Azores, Erika was losing tropical characteristics, and was declared extratropical on September 12 while located just east of the Azores.

Lack of Retirement

Because it did not affect land, the name Erika was not retired in the Spring of 1992 by the World Meteorological Organization. It is on the list of names to be used for the 2009 Atlantic hurricane season.
