Eastern Caribbean The central and southern Windwards were affected by a trough system which was enhanced by upper-level divergence. The mentioned features generated moderate to heavy showers and some thunderstorms under cloudy to overcast skies. In contrast, the Leewards and northern Windwards were under the influence of the ridge pattern and observed fair to occasionally cloudy skies with brief light showers. Here at Charnocks, Christ Church, no rainfall was recorded, while across the island accumulations ranged from 1.2mm to 6.4mm from 6am to 6pm. Trinidad and Tobago were on the southern fringe of the trough and experienced partly cloudy to cloudy skies and some showers. Across the Guianas, a ridge pattern was dominant with fair and stable weather conditions. Winds were generally gentle to moderate across the region with sustained winds of 19 knots in Barbados, and gusts up to 35 knots. Seas were slight to moderate in open water, with swell heights in the range of 1.0m to 2.0m. |

Western Caribbean An upper-level trough west of the Florida Pan handle enhanced activity associated with surface to mid-level convergence across the area. Cloudy to overcast skies, light to heavy showers and thunderstorms were observed over the northern Bahamas and Florida. A low-level trough over Hispaniola also generated occasional cloudiness and showers and thunderstorms stretching well north of the same island. Elsewhere, a weak ridge was dominant with fair to partly cloudy skies and some scattered showers reported. |

Eastern Caribbean Outlook Tonight: A ridge pattern will remain dominant across the northern Windwards and the Leeward islands. Meanwhile, the central and southern Windwards, will be affected by unstable conditions as a result of a low-level trough paired with the favourable upper-level divergence. Cloudy skies and scattered moderate to heavy showers, rain and isolated thunderstorms are likely. Barbados is forecast to remain on the northern fringe of the aforementioned activity with cloudy skies and light to heavy showers expected. Barbados Forecast Max/Min Temperatures: 30/24. Monday: No significant change in the synoptic pattern is expected from the previous night. However into the night, Barbados may experience an improvements as the activity continues to slowly shift southwards. Barbados Forecast Max/Min Temperatures: 29/25. Tuesday: Cloudy conditions and a few light showers are anticipated to remain. However, by this time, upper-level conditions will change and be less favourable across the southern section of the region. Elsewhere, no significant change is expected. Barbados Forecast Max/Min Temperatures: 30/24. Wednesday: A reduction in moisture in the mid to upper levels will prevail allowing for a mix of clear skies and clouds, with light showers expected across the island chain as a weak ridge pattern will begin to develop. Barbados Forecast Max/Min Temperatures: 30/24. Thursday: A ridge pattern will be dominant across the region with cloudy periods likely and a few showers as low-level moisture and instability linger across the southern Leewards. Barbados Forecast Max/Min Temperatures: 30/24. |

Western Caribbean Outlook Tonight: A surface to mid-level trough maintained occasionally cloudy skies and showers over Hispaniola. Further north, convergence along with the supporting upper-level support may bring showers and possible thunderstorms across the Northern and Central Bahamas. Monday: Increased upper-level instability coupled with pooling of moisture at the surface to low-levels, as a result of troughing in the vicinity of the Windward Passage will result in enhanced convection across the majority of the Greater Antilles. Showers and thunderstorms with cloudy skies are anticipated. The aforementioned trough in the Caribbean Sea will continue westward over Jamaica, generating cloudy skies and showers. Tuesday: No significant changes in the synoptic pattern is expected. Wednesday: Improving conditions are expected across eastern Cuba as a weak ridge pattern begins to rebuild. Elsewhere, unsettled weather is expected to persist. Thursday: No significant change from the previous day is forecast as unstable conditions remain across Hispaniola and the central Caribbean. |
