Depression Prompts Tropical Storm Watch for El Salvador

A potential risk posed by Tropical Depression Nineteen-E prompted the issuance of a Tropical Storm Watch for El Savador. At 5:00 p.m. EDT on Sunday the center of Tropical Depression Nineteen-E was located at latitude 10.8°N and longitude 92.5°W which put it about 300 miles (480 km) southwest of San Salvador, El Salvador. The tropical depression was moving toward the northeast 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 1005 mb.

A Tropical Storm Watch was in effect for the entire coast of El Salvador.

The circulation around Tropical Depression Nineteen-E exhibited a little more organization on Sunday afternoon. Thunderstorms began to form near the center of the circulation around the depression. More thunderstorms also started to develop in the bands 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 Nineteen-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 29°C. It will move under the southwestern part of an upper level low over the Northwestern Caribbean Sea. The upper level low will produce southwesterly winds that will blow toward the top of the tropical depression. Those winds will cause moderate vertical wind shear and the wind shear will inhibit intensification. The wind shear will not be strong enough to prevent intensification. Tropical Depression Nineteen-E is likely to intensify to a tropical storm during the next 24 hours.

The upper level trough over the Northwestern Caribbean Sea will steer Tropical Depression Nineteen-E slowly toward the northeast during the next 24 hours. On its anticipated track, the tropical depression could approach El Salvador on Tuesday. Tropical Depression Nineteen-E is forecast to stall when it gets near El Salvador. The tropical depression could bring gusty winds and locally heavy rain to the coast of El Salvador. Heavy rain could cause flash floods in some locations.

Tropical Depression Nineteen-E Forms South of Mexico

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.

Tropical Depression Forms Over Gulf of California

Tropical Depression Nineteen-E formed over the Gulf of California on Wednesday morning.  At 11:00 a.m. EDT on Wednesday the center of Tropical Depression Nineteen-E was located at latitude 26.3°N and longitude 110.9°W which put it about 35 miles (55 km) northeast of Loreto, Mexico.  It was moving toward the north at 13 m.p.h. (20 km/h).  The maximum sustained wind speed was 30 m.p.h. (50 km/h) and there were wind gusts to 40 m.p.h. (65 km/h).  The minimum surface pressure was 1004 mb.

The circulation of Tropical Depression Nineteen-E was still organizing .  There was a cluster of thunderstorms near the center of circulation.  Most of the stronger storms were east of the center.  Several short bands of showers and thunderstorms were beginning to develop north and south of the center of circulation.  Storms near the center were generating some upper level divergence which was pumping mass away to the northeast of the depression.

Tropical Depression Nineteen-E will move through an environment somewhat favorable for intensification during the next 12 hours.  The water in the Gulf of California is very warm and the depression will move over water where the Sea Surface Temperature is near 31°C.  An upper level trough west of California will produce southwesterly winds which will cause moderate vertical wind shear.  Tropical Depression Nineteen-E could intensify during the next 12 hours and it has a chance to become a tropical storm.

The upper level trough west of California will steer Tropical Depression Nineteen-E toward the north-northeast.  On its anticipated track the depression will reach the west coast of Mexico near Guaymas in about 12 hours.  It could be a tropical storm when it reaches the coast.  It will bring some gusty winds, but locally heavy rain is the greatest risk.  There is the potential for flash floods in parts of Sinaloa, Sonora and Chihuahua.  The lower portion of Tropical Depression Nineteen will weaken quickly after it makes landfall and moves over mountains in western Mexico.  The upper portion of the circulation and some of the moist air will be transported farther northeast and the remnants of the circulation could enhance rainfall farther inland.
