Eastern Caribbean Today, surface to low-level instability trailing a weak trough was enhanced by a mid to upper-level trough located to the east of the Island Chain. This activity triggered partly cloudy to cloudy skies, light to moderate showers, and periods of rain across Barbados, the Windward Islands, and the southern Leewards. No rainfall was recorded here at the BMS in Charnocks; however, the maximum rainfall accumulation recorded across the island was 4.8 mm in St. George. Across the northern Leewards and Trinidad and Tobago, mostly fair conditions were experienced as a ridge pattern was dominant. Further south across the Guianas, low-level convergence along with adequate low-level moisture triggered cloudy skies, light to moderate showers, and isolated thunderstorms across the area. Winds were generally light to moderate, peaking at 20 knots in St. Lucia and 19 knots at Charnocks, Christ Church. Sea conditions were moderate, with swell heights of 1.5 to 2.5 meters in open water. |

Western Caribbean A frontal boundary slowly transitioning into a shearline across the central Bahamas and extending across central Cuba produced cloudy to overcast skies and scattered showers. In addition, low-level convergence triggered cloudy skies and periods of rain across Hispaniola. Elsewhere, a ridge pattern was the dominant feature, allowing for mostly dry and stable weather conditions. |

Eastern Caribbean Outlook Tonight: Surface to low-level instability ahead of an approaching trough system will trigger occasionally cloudy skies and scattered light to moderate showers across the region. Barbados Forecast Max/Min Temps: 29/20. Wednesday: Another trough will drift across the region, triggering cloudy skies and scattered light to moderate showers, mainly across the northern Windwards and Leewards. Barbados is expected to be on the southern fringe of this unsettled weather. Despite this, some scattered light to moderate showers are likely. Barbados Forecast Max/Min Temps: 29/20. Thursday: Similar weather conditions to those of the previous day are expected. In addition, a low-level confluent pattern across Barbados and the southern islands will also cause unsettled conditions to persist Barbados Forecast Max/Min Temps: 29/20. Friday: A surface to low-level Atlantic high-pressure system will rebuild across the region. However, copious amounts of surface to low-level moisture on the southern periphery of the said high pressure is likely to produce a mix of clear skies and clouds with intermittent scattered light to moderate showers. Barbados Forecast Max/Min Temps: 29/20. Saturday: Similar weather conditions to those of the previous day are expected. Barbados Forecast Max/Min Temps: 29/20. |

Western Caribbean Outlook Tonight: A shearline will continue to produce unsettled weather conditions across the central Bahamas and central Cuba. Meanwhile, a confluent pattern is likely to trigger some shower activity across Hispaniola. Elsewhere, a ridge pattern will remain the dominant feature, allowing for mostly dry and stable weather conditions. Wednesday: A deep-layered northwestern Atlantic high-pressure system will rebuild across the western Caribbean. In addition, a relatively dry mid to upper-level environment will be noticeable over the region. As a result, mostly dry and stable weather conditions are forecast. Thursday: A surface to low-level trough will move across the Virgin Islands and Puerto Rico and eventually eastern Hispaniola as the day progresses. Consequently, partly cloudy skies, occasional scattered light to moderate showers with a few breaks of clear skies are forecast. Elsewhere, no significant change in weather conditions compared to the previous day is expected. Friday: The aforementioned trough is forecast to weaken across Hispaniola. Despite this, a surface to low-level confluent pattern in conjunction with copious amounts of surface to low-level moisture will form over the area. As a result, a mix of clear skies and clouds with sporadic scattered light to moderate showers is anticipated. Saturday: As the Atlantic High-pressure system rebuilds across the area, a confluent pattern on the southwestern periphery of the ridge, along with adequate low-level moisture, will trigger unsettled weather conditions across the greater Antilles. Meanwhile, across the Bahamas, a drier atmosphere will produce mostly fair conditions. |
