Depression Prompts Tropical Storm Watch for Mexico

The formation of Tropical Depression Ten-E over the Eastern North Pacific Ocean prompted the issuance of a Tropical Storm Watch for a portion of the coast of Mexico.  At 5:00 p.m. EDT on Sunday the center of Tropical Depression Ten-E was located at latitude 13.8°N and longitude 98.7°W which put the center about 175 miles (280 km) south of Punta Maldonado, Mexico.  The tropical depression was stationary.  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 1005 mb.

A Tropical Storm Watch was in effect for the portion of the coast from Punta Maldonado to Salina Cruz, Mexico.

A low pressure system over the Eastern North Pacific Ocean strengthened on Sunday afternoon and the U.S. National Hurricane Center designated the system as Tropical Depression Ten-E.  More thunderstorms formed near the center of Tropical Depression Ten-E.  Bands of showers and thunderstorms began to revolve around the center of the tropical depression.  Storms near the center of circulation began to generate upper level divergence that pumped mass away from the tropical depression.

Tropical Depression Ten-E will move through an environment favorable for intensification during the next 24 hours.  The tropical depression will be over water where the Sea Surface Temperatures are near 30°C.  It will be in a region where the upper level winds are weak and there will be little vertical wind shear.  Tropical Depression Ten-E is likely to strengthen to a tropical storm during the next 24 hours.

Tropical Depression Ten-E will be in an area where the steering winds are weak during the next 24 hours.  The tropical depression is likely to move very slowly toward the north on Monday.  On its anticipated track, Tropical Depression Ten-E will move a little closer to Mexico.

Tropical Depression Ten-E Forms South of Baja California

Tropical Depression Ten-E formed over the Eastern North Pacific Ocean south of Baja California on Saturday afternoon. At 5:00 p.m. EDT on Saturday the center of Tropical Depression Ten-E was located at latitude 18.0°N and longitude 111.5°W which put it about 355 miles (570 km) south-southwest of the southern tip of Baja California. The tropical depression was moving toward the west-northwest at 10 m.p.h. (16 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 Baja California exhibited more organization on Saturday afternoon and the National Hurricane Center designated the system as Tropical Depression Ten-E. The distribution of thunderstorms around Tropical Depression Ten-E 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. Tropical Depression Ten-E was moving under the southwestern part of an upper level ridge over northern Mexico. The upper level ridge was producing easterly winds that were blowing toward the top of the tropical depression. Those winds were causing moderate vertical wind shear and the shear was the primary reason for the asymmetrical distribution of thunderstorms.

Tropical Depression Ten-E will move through an environment marginally favorable for intensification during the next 24 hours. The tropical depression will move over water where the Sea Surface Temperatures are near 27˚C. However, the upper level ridge over northern Mexico will continue to cause moderate vertical wind shear. The wind shear will inhibit intensification. Tropical Depression Ten-E could strengthen to a tropical storm if the upper level winds weaken for a few hours. The tropical depression will move over cooler water on Monday, which will make the environment unfavorable for intensification.

Tropical Depression Ten-E will move around the southern side of a high pressure system over northern Mexico and the Eastern North Pacific Ocean. The high pressure system will steer Tropical Depression Ten-E toward the west-northwest during the next 24 hours. On its anticipated track Tropical Depression Ten-E will move farther away from Baja California.
