Tropical Depression One-E formed over the Eastern North Pacific Ocean south of Mexico on Friday night. At 11:00 p.m. EDT on Friday the center of Tropical Depression One-E was located at latitude 12.8°N and longitude 97.9°W which put it about 220 miles (355 km) south-southwest of Puerto Angel, Mexico. Tropical Depression One-E was moving toward the west at 7 m.p.h. (11 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and and there were wind gusts to 45 m.p.h. (75 km/h).

More thunderstorms formed near the center of a low pressure system over the Eastern North Pacific Ocean south of Mexico on Friday night and the National Hurricane Center designated the system as Tropical Depression One-E. The inner end of a rainband wrapped around the northern and western sides of the center of Tropical Depression One-E. Other bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center began to generate upper level divergence that pumped mass away from the tropical depression.

Tropical Depression One-E will move through an area favorable for intensification during the next 48 hours. The depression will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the western part of the axis of an upper level ridge over Central America and the Eastern North Pacific Ocean. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear.. Tropical Depression One-E will intensify to a tropical storm on Saturday and it could strengthen to a hurricane by the end of the weekend.

Tropical Depression One-E will move around the western part of a high pressure system over Central America and the Eastern North Pacific Ocean. The high pressure system will steer the tropical depression toward the north during the next 36 hours. On its anticipated track, Tropical Depression One-E will move closer to Mexico. The depression could approach the coast of Mexico on Monday. It could be a hurricane when it approaches Mexico. The government of Mexico is likely to issue watches and/or warnings for a portion of the coast on Saturday.
