Eastern Caribbean ********************** TROPICAL WAVES AT (0600UTC/ 2AM LST) ********************** A tropical wave was analyzed near 33W south of 15N, moving west at 5 - 10 knots. Outlook (18Z/03) Time/Date-------00Z/04----12Z/04-----00Z/05----12Z/05----00Z/06---12/06----00/07--- Wave Position----31W-------32W--------33W-------33W-------34W-----36W-----38W ********************************************************************************************* A strong surface to mid-level north-central Atlantic high-pressure system was the dominant feature across Barbados and the eastern Caribbean during the night and through to daybreak. Consequently, mostly fair weather conditions were experienced. Trinidad and Tobago also encountered fair weather conditions as the high-pressure system was also dominant over that area. Over the Guianas, a surface to low-level trough across the border of Guyana and Suriname produced a mix of clouds and clear skies with a few showers and thunderstorms. Winds were generally light to moderate over the region, peaking at 17 knots in St. Lucia and 16 knots here at Charnocks in Christ Church. Seas were slight to moderate in open water, with swell peaking at 1.5m in open water. |

Western Caribbean Unsettled weather conditions remained over the Bahamas and Cuba as the frontal boundary stalled across that area. At the same time, a surface to low-level trough moving westward from over the USVI triggered a few passing showers over the central Caribbean. |

Eastern Caribbean Outlook Today: A surface to low-level trough will drift across Barbados and the island chain. During this time, occasional light to moderate showers with partly cloudy skies can be expected. Barbados Forecast Max/Min Temps: 33/25. Friday: Instability will persist across Barbados and the southern Windwards with a favourable upper-level pattern supporting moderate showers and the possibility for isolated thunderstorms. Over the Leewards and northern Windwards, a ridge pattern will dominate with fair to partly cloudy skies expected. Barbados Forecast Max/Min Temps: 33/25. Saturday: The surface to mid-level ridge pattern will be dominant across Barbados, and the northern half of the island chain, allowing for mostly dry and stable weather conditions. However, the combination of a surface to low-level confluent pattern and deep-layered moisture on the southern periphery of the ridge is forecast to produce sporadic light to moderate showers under partly cloudy skies over Trinidad and Tobago and the extreme southern Windward Islands. Barbados Forecast Max/Min Temps: 32/25. Sunday: The surface to mid-level ridge pattern will be dominant across Barbados, and the eastern Caribbean, allowing for mostly dry and stable weather conditions. Barbados Forecast Max/Min Temps: 32/25. |

Western Caribbean Outlook Today: Unsettled weather conditions will remain over the Bahamas and Cuba as the frontal boundary stalls across that area. A surface to mid-level north-central Atlantic high-pressure system will be noticeable from the USVI to eastern Cuba. Despite this, afternoon localized showers and thunderstorms are still possible across the Greater Antilles, which may be further enhanced by an upper trough over the central Caribbean. Friday: No significant change in weather conditions from the previous day is expected. Saturday: Model data indicate some weakening of the aforementioned frontal boundary. However, scattered showers and isolated thunderstorms will persist with gradual improvement by evening. In addition, a mid to upper-level trough over Puerto Rico and Hispaniola could initiate inclement weather conditions across that area. Sunday: No significant change in weather conditions from the previous day is expected. |
