Showers and thunderstorms have changed little in organization in association with an area of low pressure located roughly halfway between the Cabo Verde Islands and the Lesser Antilles.

Environmental conditions are forecast to be conducive for development, as long as this system remains far enough removed from Tropical Storm Philippe to its west.

A tropical depression or storm is expected to form in the next day or so while the system moves northwestward across the central tropical Atlantic.
