List of Storms in The 2006 Pacific Hurricane Season - Tropical Depression Eighteen-E

Tropical Depression Eighteen-E

The origins of Tropical Depression Eighteen-E were from a tropical wave that exited the coast of Africa on October 7. It briefly spawned a low-pressure area as the wave continued westward without development. On October 20, the wave entered the Pacific Ocean, developing an area of thunderstorms about four days later. By 1200 UTC on October 26, a tropical depression formed about 155 mi (260 km) south of Manzanillo. Initially, Tropical Depression Eighteen-E was located in an area of light wind shear, and the NHC anticipated further organization and strengthening to near hurricane status. The tropical depression initially maintained a steady westward motion away from the Mexican coastline, due to a ridge north of the cyclone. By October 17, convection had decreased, and the depression was not forecast to intensify as much. Possibly due to intrusion of dry air, the circulation became exposed from the thunderstorms, and having weakened, it turned to a southward drift. By 0000 UTC on October 28, the system had weakened to a non-convective remnant low, which dissipated the following day.
