The National Hurricane Center in Miami has announced that an area of disturbed weather in the eastern Atlantic has become Tropical Depression Four.

At 11 a.m., TD 4 was centered about 1,365 miles east of the Lesser Antillles Islands, or about 2,400 miles south-southeast of Charleston, at latitude 12.6 north, longitude 41.1 west. The depression was moving toward the west-northwest at 17 mph.

TD 4 is expected to continue this track for the next couple of days. Maximum sustained winds are near 35 mph, with some higher gusts. Some strengthening is forecast during the next 48 hours, and the depression could become a tropical storm by tonight or Tuesday, NHC officials said.

If the system develops into a tropical storm, with sustained winds of 39 mph, it would be named Colin.

According to AccuWeather forecasters, the disturbance is spinning in an environment conducive for tropical development as it churns over water that is warmer than normal. Strong wind shear that would rip apart the low and prevent strengthening does not lie in its path.

Disruptive wind shear was the reason for the demise of Tropical Storm Bonnie last week.

Most forecast models have the current Atlantic disturbance continuing its course through the week then trailing north along the U.S. coast.
