Eastern Caribbean A shearline generated cloudy to overcast skies, showers and isolated thunderstorms across the Leewards and northern Windwards. Meanwhile, the southern portion was affected by a combination of mid to upper instability and lower-level convergence which also brought similar cloudy to overcast skies but with less shower activity. Trinidad and Tobago and the Guianas saw cloudy skies along with scattered showers, periods of rain, and isolated thunderstorms due to the low-level convergence and upper-level support. Winds were light to moderate across the region, peaking at 10 knots here in Barbados. Seas were slight to moderate in open water, peaking between 1.0m and 1.5m. |
Western Caribbean The Bahamas was under the influence of a ridge pattern where mostly fair conditions persisted. The remainder of the Greater Antilles was under the influence of a shear line which resulted in cloudy skies with showers and isolated thunderstorms. |
Eastern Caribbean Outlook Today: Moisture levels across the eastern Caribbean remain elevated; periodic cloudy to overcast skies with light to moderate showers are expected along with potential isolated thunderstorms. These conditions are a result of an upper jet supporting areas of lower-level convergence across the southern portion of the region. The northern portion is being affected by a weak shear line that is forecast to remain there until mid-week. Barbados Forecast Max/Min Temps: 29/22. Monday: Current model guidance is leaning towards sunnier skies across Barbados and the southern portion of the region with a ridge pattern being dominant. Elsewhere, no significant change is forecast. Barbados Forecast Max/Min Temps: 30/22. Tuesday: No significant change is forecast. Barbados Forecast Max/Min Temps: 30/22. Wednesday: An abundance of moisture will continue encouraging shower activity across the Leewards. Elsewhere, a ridge pattern will be dominant. Barbados Forecast Max/Min Temps: 30/22. |
Western Caribbean Outlook Today: A shear line across the Greater Antilles with its corridor of surface to mid-level moisture will continue to bring showers, cloudy to overcast skies and scattered thunderstorms to the region. Meanwhile, the Bahamas will be under the influence of a ridge pattern: partly cloudy skies are forecast. Monday: No significant change is forecast across the western Caribbean. Tuesday: Current model guidance suggests a reduction in atmospheric moisture across Cuba and the Bahamian Islands. Elsewhere, the shearline and its moisture will remain the dominant feature producing occasionally showers and thunderstorms Wednesday: No significant change is forecast across the western Caribbean. |
