Tropical weather outlook

The Atlantic High-pressure system will maintain light to moderate easterly winds and warm conditions across the region, during the next 24 hours. A surface trough is expected to cause an increase in cloudiness, showers and possibly thunderstorms mainly over the northern portion of Lesser Antilles, during the forecast period. Two tropical waves located over the central and eastern Tropical Atlantic are moving westward near 15 mph or 24 km/h. A third tropical wave is forecast to move off the coast of west Africa tomorrow. Although environmental conditions are not particularly conducive, but some slow development is possible while it moves generally northwestward across the far eastern Tropical Atlantic.
