Tropical Depression Thirteen-E Forms Southwest of Baja California

Tropical Depression Thirteen-E formed over the Eastern North Pacific Ocean southwest of Baja California on Friday afternoon.  At 5:00 p.m. EDT on Friday the center of Tropical Depression Thirteen-E was located at latitude 11.2°N and longitude 128.4°W which put the center about 1460 miles (2350 km) west-southwest of the southern tip of Baja California.  The tropical depression 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 there were wind gusts to 45 m.p.h. (75 km/h).  The minimum surface pressure was 1006 mb.

A low pressure system over the Eastern North Pacific Ocean southwest of Baja California strengthened on Saturday afternoon and the U.S. National Hurricane Center designated the system as Tropical Depression Thirteen-E.  More thunderstorms formed near the center of Tropical Depression Thirteen-E on Friday afternoon.  Other bands of showers and thunderstorms were revolving around the center of the tropical depression.  Storms near the center of circulation generated upper level divergence that pumped mass away from the tropical depression.

Tropical Depression Thirteen-E will move through an environment that will be somewhat favorable for intensification during the next 24 hours.  The tropical depression will move over water where the Sea Surface Temperatures are near 28°C.  It will move under the western part of an upper level ridge over the Eastern North Pacific Ocean.  The upper level ridge will produce easterly winds that will blow toward the top of the depression’s circulation.  Those winds will cause some vertical wind shear.  The wind shear will inhibit intensification, but the shear may not be enough to prevent intensification.  Tropical Depression Thirteen-E could intensify to a tropical storm during the next 24 hours.

Tropical Depression Thirteen-E will move south of a high pressure system over the Eastern North Pacific Ocean.  The high pressure system will steer the tropical depression toward the west during the next 24 hours.  On its anticipated track, Tropical Depression Thirteen-E will move farther away from Baja California.

Tropical Depression Forms South of Mexico, Watch Issued

Tropical Depression Thirteen-E formed over the Eastern North Pacific Ocean south of Mexico on Thursday and the government of Mexico issued a Tropical Storm Watch for a portion of the coast. At 8:00 p.m. EDT on Thursday the center of Tropical Depression Thirteen-E was located at latitude 12.8°N and longitude 95.6°W which put it about 215 miles (345 km) south-southeast of Puerto Angel, Mexico. The tropical depression was moving toward the northwest at 3 m.p.h. (5 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 Tropical Storm Watch was in effect for the portion of the coast from Laguna de Chacahua to Zihuatanejo, Mexico. The Tropical Storm Watch includes Acapulco.

The circulation around a low pressure system over the Eastern North Pacific Ocean strengthened on Thursday and the National Hurricane Center designated the system as Tropical Depression Thirteen-E. Tropical Depression Thirteen-E had a well defined low level center of circulation but the distribution of thunderstorms was asymmetrical. Most of the thunderstorms were occurring in bands in the western half of the tropical depression. Bands in the eastern half of the circulation consisted primarily of showers and lower clouds. Storms near the center of circulation generated upper level divergence that pumped mass away to the west of the tropical depression.

Tropical Depression Thirteen-E will move through an environment somewhat favorable for intensification during the next 36 hours. The tropical depression will move over water where the Sea Surface Temperatures are near 30˚C. It will move under the southern side of an upper level ridge over Mexico. The upper level ridge will produce easterly winds that will blow toward the top of the tropical depression. Those winds will cause vertical wind shear and the wind shear will inhibit intensification. Tropical Depression Thirteen-E is likely to strengthen gradually during the next 36 hours.

Tropical Depression Thirteen-E will move around the southwestern part of a high pressure system that extends over Mexico. The high pressure system will steer the tropical depression toward the northwest during the next 36 hours. On its anticipated track Tropical Depression Thirteen-E will approach the southwest coast of Mexico on Saturday morning. It is likely to be a tropical storm when it approaches the coast.
