Tropical Depression Nineteen-E formed over the Eastern North Pacific Ocean south of Mexico on Wednesday night. At 11:00 p.m. EDT on Wednesday the center of Tropical Depression Nineteen-E was located at latitude 15.2°N and longitude 101.3°W which put it about 175 miles (280 km) south of Zihuatanejo, Mexico. The tropical depression was moving toward the west-northwest at 5 m.p.h. (8 km/h). The maximum sustained wind speed was 35 m.p.h. (55 km/h) and there were wind gusts to 45 m.p.h. (75 km/h). The minimum surface pressure was 1007 mb.

A low pressure system over the Eastern North Pacific Ocean south of Mexico strengthened on Wednesday night and the National Hurricane Center designated the system as Tropical Depression Nineteen-E. More thunderstorms were developing near the center of Tropical Depression Nineteen-E. Bands of showers and thunderstorms were revolving around the center of circulation. Storms near the center generated upper level divergence that pumped mass away from the tropical depression.

Tropical Depression Nineteen-E will move through an environment favorable for intensification during the next 48 hours. The tropical depression will move over water where the Sea Surface Temperatures are near 29˚C. It will move under the axis on an upper level ridge over the Eastern North Pacific. The upper level winds are weak and there will be little vertical wind shear. Tropical Depression Nineteen-E will strengthen during the next 48 hours. It could intensify to a tropical storm during the next 12 hours. It could strengthen to a hurricane by Friday evening.

Tropical Depression Nineteen-E will move around the southwestern side of a surface high pressure system centered over northern Mexico. The high pressure system will steer the tropical depression toward the west-northwest during the next 48 hours. On its anticipated track Tropical Depression Nineteen-E will move parallel to the southwest coast of Mexico. It will turn more toward the north when it reaches the western end of the high pressure system during the weekend.
