Hurricane-force winds extend outward up to 30 miles from the center and tropical storm-force winds extend outward up to 70 miles. The associated thunderstorm activity does show some signs organization, but still lacks a defined center.
It is not forecast to impact Florida, and is expected to dissipate within 72 hours, the Hurricane Center said. It will be battling dry air and strong wind shear over the Caribbean, which will likely hinder further tropical development.
Even if no cyclone forms, the system is expected to dump heavy rain on the Lesser Antilles.
The system colored in yellow on the above map, dubbed Invest 96L, is an area of disturbed weather located about 800 miles west-southwest of the Cabo Verde Islands.
The system is dealing with dry air, so development, if any, is expected to be slow as the area moves to the west at 15-20 miles per hour.
Aircraft flew into the storm earlier Monday and determined the system was organized enough to be a tropical storm.
Another tropical wave, with a low chance of development during the next two days, will continue to drift slowly west-northwest.
