A weak tropical wave moved off the coast of Africa on August 7. It tracked across the Atlantic Ocean and Caribbean Sea without development due to strong wind shear. The wave then split into two, with the northern portion dissipating over Cuba on August 15 and the southern portion continuing westward. The wave crossed Central America and entered the Pacific Ocean on August 16. Deep convection increased over the wave upon entering the Pacific, and early on August 19 it started to become better organized. After the development of a low-level circulation, the system organized into Tropical Depression Fourteen-E on August 20 while located about 275 miles (445 km) south-southwest of Manzanillo, Colima.
