Tropical Depression Three formed over the Atlantic Ocean east of the Lesser Antilles on Monday morning. At 11:00 a.m. EDT on Monday the center of Tropical Depression Three was located at latitude 11.0°N and longitude 40.3°W which put it about 1425 miles (2295 km) east of the Lesser Antilles. Tropical Depression Three was moving toward the west at 21 m.p.h. (33 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 circulation within a tropical wave previously designated as Invest 92L strengthened on Monday morning and the National Hurricane Center designated the system as Tropical Depression Three. More thunderstorms were developing near the center of Tropical Depression Three. Other 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 Three will move through an environment favorable for intensification during the next 36 hours. The tropical depression will move over water where the Sea Surface Temperatures are near 28˚C. It will move under the axis of an upper level ridge over the tropical Atlantic Ocean. The upper level winds are weak near the axis of the ridge and there will be little vertical wind shear. Tropical Depression Three is likely to strengthen to a tropical storm during the next 24 hours. It could strengthen to a hurricane later this week.

Tropical Depression Three will move south of a subtropical high pressure system over the Atlantic Ocean. The subtropical high will steer the tropical depression toward the west during the next 36 hours. It could move more toward the west-northwest later this week. On its anticipated track, Tropical Depression Three could approach the Lesser Antilles on Thursday. It could be a hurricane by that time.
