Tropical Depression Two Forms East of the Lesser Antilles

Tropical Depression Two formed east of the Lesser Antilles on Thursday morning.  At 11:00 a.m. EDT on Thursday the center of Tropical Depression Two was located at latitude 10.2°N and longitude 41.4°W which put it about 1385 miles (2230 km) east-southeast of the Lesser Antilles.  It was moving toward the west at 16 m.p.h. (26 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 1009 mb.

A distinct area of low pressure developed in the northern end of a tropical wave on Thursday and the National Hurricane Center designated the system as Tropical Depression Two.  The circulation of the depression was quite small.  Several short bands of showers and thunderstorms were revolving around the center of circulation.  Storms near the center were beginning to generate upper level divergence which was pumping mass away from the depression.

Tropical Depression Two will move through an environment somewhat favorable for intensification.  It will move over water where the Sea Surface Temperature is near 26.5°C.  However, there is cooler water to the north of the anticipated track and the depression will not intensify if it moves over the cooler water.  An upper level ridge north of the tropical depression will produce easterly winds which will blow toward the top of the circulation.  The wind speeds will be similar at all levels and there will be little vertical wind shear.  Tropical Depression Two is forecast to strengthen into a tropical storm during the next day or two.

Tropical Depression Two was moving around the southern side of the subtropical ridge over the Atlantic Ocean and the ridge was steering the depression toward the west.  The ridge is forecast to steer the depression toward the west-northwest during the next two or three days.  On its anticipated track Tropical Depression Two could be east of the Lesser Antilles on Sunday.
