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.
