TROPICAL WEATHER OUTLOOK

The Inter-Tropical Convergence Zone is active over the southern portion of the Lesser Antilles. Low-level clouds drifting with the wind flow, will produce a few showers over the remainder of the region, during the next 24 hours.

Activity associated with a tropical wave located over the central tropical Atlantic has diminished. Development of this system appears unlikely during the next day or two, as it moves generally northwestward near 15 mph or 24 km/h.

Another tropical wave has emerged off the west coast of Africa. Some slow development of this system is possible during next week, while it moves west-northwestward near 20 mph or 23 km/h.
