Hurricane Ginger originated in a cold-core upper-level low that persisted for several days in early September in the Western Atlantic Ocean. The upper-level low was located within a large, persistent area of convection from the Gulf of Mexico through the central Atlantic, which resembled the Intertropical Convergence Zone but at a higher latitude. The convective feature was influenced by an anticyclone located over northern South America, which was opposite of the typical flow for September. The anticyclone also led to the formation of Hurricane Fern, Tropical Storm Heidi, and two tropical depressions. By September 5, the low had descended to the surface as its thermal structure warmed, and the next day it developed into a tropical depression about 235 mi (375 km) northeast of the Bahamas.
