Eastern Caribbean A surface to mid-level north central Atlantic high-pressure system was the dominant feature across Barbados and the eastern Caribbean. In addition, a relatively dry lower to upper-level environment remained over the region. Despite this, the BMS Dual polar Doppler Radar revealed some small cloud patches traversing the island chain. As a result, mostly clear, and breezy weather conditions were occasionally interrupted by partly cloudy to cloudy skies with some isolated showers. 11.0 mm was recorded at the BMS Main Office at Charnocks between 6 pm and 6 am, where rainfall accumulations across the south of the island ranged between 0.4 mm and 7.2 mm over the same period. Similar weather conditions were encountered over Trinidad and Tobago due to the dominant ridge pattern. Farther south, across the Guianas, wind surge coupled with surface to low-level confluence and a favorable upper-level environment, generated showers across French Guyana, which slowly subsided as the night progressed, as unsettled weather conditions drifted westward across Suriname and Guyana under mostly cloudy skies and some isolated to scattered showers. Winds across the region were moderate and peaking at 24 knots, with a gust near a passing shower of 35 knots here at Charnocks in Christ Church and 22 knots in St. Lucia. Meanwhile, BMS Drone data revealed sea swells peak at 2.7m in open waters to the east of the island. A small craft and high surf advisory is in effect for above normal sea swells. Sea bathers are encouraged to use beaches with active lifeguards on duty. |

Western Caribbean A surface to mid-level north central Atlantic high-pressure system was the dominant feature across the western Caribbean. In addition, a relatively dry lower to upper-level environment remained over the region. As a result, mostly fair weather conditions were experienced. Meanwhile, a surface to low-level trough extending NE through SW from near 35N 56W to across the northeast of Hispaniola generated some isolated thunderstorms across the Windward Passage and eastern Hispaniola. |

Eastern Caribbean Outlook Today: A surface to mid-level north central Atlantic high-pressure system will be the dominant feature across Barbados and the eastern Caribbean. In addition, a relatively dry lower to upper-level environment will exist over the region. However, during the morning, some low-level cloud patches will traverse the island chain triggering some isolated to scattered showers. As a result, mostly fair, cool, and breezy weather conditions can be expected, by the mid-morning. Barbados Forecast Max/Min Temps: 31/23. Wednesday: Model data indicates numerous low-level cloud patches associated with low-level moisture to drift across the eastern Caribbean. Consequently, early morning and late evening intermittent light showers are forecast. Barbados Forecast Max/Min Temps: 31/23. Thursday: Similar conditions to the previous day will persist. However, by late evening a weak surface to low-level shear line will move across the region producing cloudy skies and showers. Barbados Forecast Max/Min Temps: 31/23. Friday: A deep-layered Atlantic high-pressure system will be the dominant feature across Barbados and the eastern Caribbean. In addition, a relatively dry lower to upper-level environment will remain over the region. As a result, mostly fair, cool, and breezy weather conditions can be expected. Barbados Forecast Max/Min Temps: 31/23. Saturday: Similar conditions to the previous day will persist. However, by late evening a surface to low-level confluence coupled with a pooling of low-level moisture will move across the region producing cloudy skies and showers. Barbados Forecast Max/Min Temps: 30/23. |

Western Caribbean Outlook Today: A surface to mid-level north central Atlantic high-pressure system will be the dominant feature across the western Caribbean. In addition, a relatively dry lower to upper-level environment will exist over the region. As a result, mostly fair weather conditions are forecast. Meanwhile, unsettled weather conditions will be maintained across Hispaniola as a surface to low-level prefrontal trough system drifts eastward toward Puerto Rico. Wednesday: The aforementioned trough is forecast to move slightly eastward over Puerto Rico. An upper-level Jet over the central Caribbean is likely to enhance scattered moderate showers and possible thunderstorms between Hispaniola, Puerto Rico, and the Virgin Islands. Thursday: The trough is forecast to weaken. However, lingering surface to low-level moisture between eastern Cuba and eastern Hispaniola including Jamaica and the southern Bahamas is likely to produce cloudy skies and a few passing showers. Friday: No significant change in weather conditions from the previous day is expected. However, a frontal boundary moving southeastward from the Florida Panhandle is likely to trigger a few showers over the northern Bahamian Islands. |
