WEATHER SUMMARY:

TROPICAL WAVES:

 

 

One tropical wave remained to the east of the Caribbean region today. This wave which was located near 35°W yesterday, weakened considerably as it progressed to near 47°W today.  Meanwhile the axis of the wave now affecting the southern Windwards had already pass the islands and was located near 61/62°W south of 16°N, moving westwards near fifteen to twenty knots.

BARBADOS AND EASTERN CARIBBEAN OUTLOOK

Residual moisture associated with the tropical wave will continue to spread some scattered showers and isolated thunderstorms over the southern islands tonight and into tomorrow. A dense layer of Sahara dust associated with this wave will probably lessen deep shower activity over these islands. Meanwhile the northern islands will continue to enjoy generally fair and hazy weather conditions tonight and early tomorrow. However, fair conditions will be short-lived over these islands(the north) as models suggest that the weak wave near 47°W will increase instability and showers by late tomorrow.Thereafter, as the upper level Atlantic ridge expands across the chain a strong upper level southerly flow will pull ITCZ moisture northwards on Sunday. This will allow for higher moisture levels over the region and increase showers over Barbados and the southern Windwards. By Monday, a building ridge pattern will begin to once again re-establish itself across the chain and this will allow for a drying trend. A temporary marginally reduction in surface winds is anticipated tomorrow (averaging 15knots) however by Sunday and into early next weekend easterly to east southeasterly breezes averaging fifteen to twenty knots will sustain wave heights in the vicinity of 2.5m. The layer of dust haze will persist, varying in intensity over the weekend however it is not expected to lift out of the area until early next week.

 

CENTRAL AND WESTERN CARIBBEAN OUTLOOK

 

The upper level low will maintain weak instability over the northern Bahamas tonight and into

tomorrow. Hence scattered showers are likely to continue over these islands. Meanwhile, as the

tropical wave (along 76°W) moves out of the area without much fanfare subsidence associated with the

broad surface to low level ridge will prohibit deep convective activity over the other islands. The very

large and dense area of Saharan dust will move across the Central islands reducing horizontal

visibilities over Puerto Rico and Hispaniola by tomorrow.
