A new tropical depression has formed in the Atlantic and is forecast to become a powerful hurricane by the end of the week, according to the National Hurricane Center.

On Tuesday, the center of Tropical Depression 13, which formed between Western Africa and the Windward Islands, is expected to continue to move toward the west-northwest at 15 mph with sustained winds of 35 mph, according to the NHC.

The tropical depression is then expected to strengthen into Tropical Storm Lee late Tuesday or early Wednesday, CBS News Miami reported. It is forecast to become a potential “major hurricane,” the NHC said.
