Eastern Caribbean Throughout the day, a weak surface to low-level trough was dominant across Barbados and the island chain. Due to a higher concentration of moisture and instability, the Leewards and northern windwards experienced partly cloudy to cloudy skies and scattered light to moderate showers. Across Barbados and the remainder of the Windwards, conditions were more dry and stable with a mix of sunshine and clouds, as well as a few isolated light showers experienced. Here at Charnocks, Christ Church, no rainfall was measured to have fallen today, with islandwide accumulations being similarly minimal. Toward the south, moisture and instability trailing the trough brought cloudiness and showers to Trinidad, while Tobago experienced more fair conditions, similar to their northern neighbours. Across the Guianas, skies were partly cloudy to cloudy with light showers, with surface to low-level convergence and diurnal heating bringing some isolated thunderstorms to coastal Guyana during the afternoon. Winds across the region were moderate to breezy at times, with speeds peaking at 22 knots in St. Lucia. Seas across the region remain moderate to rough, with swells peaking around 3.0m in open water. A SMALL CRAFT ADVISORY REMAINS IN EFFECT FOR THE ISLAND. |

Western Caribbean Throughout the day, a deep-layered ridge pattern was dominant across the Western Caribbean, bringing mostly fair skies interrupted by periods of cloudiness and showers, due to perturbations within the flow. |

Eastern Caribbean Outlook Tonight: The weak low-level trough will continue westwards. Moisture and instability trailing the trough axis will bring occasionally cloudy skies and scattered light to moderate showers to the southern Windwards. Barbados and the central Windwards will be on the northern periphery of this activity, with a mix of clear skies and clouds and a few scattered light showers expected. Elsewhere, the ridge pattern will be dominant with fair skies and isolated showers expected. Barbados Forecast Max/Min Temps: 27/23. Sunday: Surface to low-level moisture trailing the aforementioned trough is likely to maintain a few scattered showers across the extreme southern Windward Islands. Elsewhere, perturbations within the dominant ridge flow will continue to bring occasional periods of cloudiness and showers, interrupting otherwise fair skies. Barbados Forecast Max/Min Temps: 30/23. Monday: A weak shearline within the ridge flow will bring occasional cloudiness and scattered light to moderate showers to Barbados and the island chain as it traverses the region. Barbados Forecast Max/Min Temps: 30/23. Tuesday: Perturbations within the dominant ridge flow will continue to bring occasional periods of cloudiness and sharp showers to Barbados and the island chain, interrupting otherwise fair skies. Barbados Forecast Max/Min Temps: 30/23. Wednesday: No significant change in weather conditions compared to the previous day is expected. Barbados Forecast Max/Min Temps: 30/23. |

Western Caribbean Outlook Tonight: A deep-layered ridge pattern will be dominant across the Western Caribbean. Perturbations within the ridge flow will interrupt the mostly fair conditions with the occasional period of cloudiness and light showers. Sunday: A surface to mid-level western Atlantic ridge pattern will be the dominant feature across the western Caribbean. As a result, a mix of clear skies and clouds with a few isolated showers is forecast. Monday: A frontal boundary moving across the northern Bahamas and extending over western Cuba will generate cloudy to overcast skies, scattered showers, periods of rain, and possible thunderstorms across those parts. Elsewhere, the ridge pattern will remain dominant. Tuesday: As the frontal boundary will maintain unsettled weather across western Cuba and the Bahamas, it will stall across these islands. Simultaneously, a weak shearline will exit the eastern Caribbean. The Virgin Islands and Puerto Rico will be on the northern periphery of the associated activity, with occasionally cloudy skies and sharp showers anticipated. Elsewhere, the ridge pattern will remain dominant. Wednesday: Though the frontal boundary across Cuba and the Bahamas will gradually weaken, it will continue to maintain some unsettled weather across the islands. Elsewhere, perturbations within the dominant ridge flow will continue to bring occasional periods of cloudiness and showers, interrupting otherwise fair skies. |
