Tropical Depression Three developed over the Bay of Campeche on Monday afternoon. At 5:00 p.m. EDT on Monday the center of Tropical Depression Three was located at latitude 19.6°N and longitude 91.2°W which put it about 55 miles (90 km) north-northeast of Carmen, Mexico. The depression was moving toward the west-northwest at 7 m.p.h. (11 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 government of Mexico issued a Tropical Storm Warning for the portion of the coast from Campeche to Puerto de Veracruz.
The remnants of the center of circulation of former Tropical Storm Amanda moved northward across Honduras and emerged over the eastern Bay of Campeche on Monday afternoon. The National Hurricane Center designated the system as Tropical Depression Three and initiated advisories on the system.
More thunderstorms began to form on the northern side of Tropical Depression Three after the center of circulation moved over the eastern Bay of Campeche. More thunderstorms were developing near the center. Bands of showers and thunderstorms that included the remnants of the the circulation of former Tropical Storm Amanda were revolving around the center of the depression.
Tropical Depression Three will move through an environment favorable for intensification during the next 24 hours. The depression will move over water where the Sea Surface Temperature is near 29°C. It will move under the western side of an upper level ridge over the northwestern Caribbean Sea. The ridge will produce northerly winds which will blow toward the top of the depression. Those winds will cause some vertical wind shear, but the shear will not be strong enough to prevent intensification. Tropical Depression Three is likely to intensify into a tropical storm on Tuesday.
Tropical Depression Three will move around the northern side of a larger counterclockwise circulation sometimes called a Central American Gyre (CAG). The CAG will steer the depression toward the west-northwest during the next 12 to 24 hours. The depression could move toward the southwest on Tuesday when it moves around the northwestern part of the CAG. On its anticipated track Tropical Depression Three could approach the coast around the southern Bay of Campeche. The depression could drop heavy rain over Campeche, Tabasco and eastern Veracruz. The heavy rain could cause flash floods in some locations.
