"The Tropics are heating up with 3 systems that we are monitoring," the agency warned, as it shared a map of the weather patterns sparking concern out at sea.

The National Hurricane Center is monitoring multiple areas, including Tropical Storm Dexter. Dexter formed on Sunday and is expected to stay in the Atlantic as a tropical storm. It will then weaken into a post-tropical cyclone by Wednesday. But the NHC is monitoring two more areas that could develop.
