Tropical Depression 4 emerges in the Central Atlantic and could become a named storm today
Tropical Depression 4 emerged in the Central Atlantic on Monday morning and was forecast to grow into Tropical Storm Colin possibly as early as Monday afternoon.

Under the preliminary forecast, subject to large errors, the system was forecast to approach the northern Lesser Antilles on Wednesday and then turn north in the general direction of the Carolinas. It also could potentially swing out to sea.

It was not projected to grow into a hurricane over the next five days, but rather remain a tropical storm with maximum sustained winds of 60 mph. That is because it was expected to encounter wind shear near Puerto Rico, forecasters said.

As of 11 a.m. EDT on Monday, Tropical Depression 4 was 1,365 miles east of the Lesser Antilles, moving northwest at 17 mph with sustained winds of 35 mph. It was about 2,700 miles southeast of Cape Hatteras, N.C.
