Miami, Florida (CNN) -- Tropical Depression Four has formed in the Atlantic Ocean, about 1,365 miles east of the Lesser Antilles, the National Hurricane Center said Monday.

The system's maximum sustained winds were at 35 mph, just short of the 39 mph needed to classify it as a tropical storm, the Hurricane Center said. If it becomes a tropical storm, it will be given the name Colin.

As of 11 a.m. ET, the depression was moving to the west-northwest at near 17 mph. "A continued motion toward the west-northwest with an increase in forward speed is expected over the next couple of days," forecasters said.

Some strengthening is expected, and the depression could become a tropical storm by Monday night or Tuesday.

The depression poses no immediate threat to land, the Hurricane Center said. Tracking maps show it turning northwest in the Atlantic through Saturday.
