An Atlantic high-pressure system is expected to remain the dominant feature across the Eastern Caribbean through the weekend. Isolated showers are possible, due to surface to low level confluence along the southern periphery of this feature. These showers will generally be fairly brief, occurring mainly during the early morning and interrupting settled conditions.
This high-pressure system, due to a tight pressure gradient, is producing breezy conditions across the Eastern Caribbean, with winds between 15-30 KM/H and gusts to 50 KM/H.
These breezy conditions are also generating moderate seas and will continue to do so through next Wednesday. Waves in open waters will be up to 2.5 meters and less than 1.0 meters in sheltered areas. Small craft operators, sea bathers and other persons with marine interests should exercise caution.
Temperatures are expected to be fairly mild through the weekend, with highs between 30-31°C across both islands. Lows in Trinidad near 22-23°C and 23-24°C in Tobago. Note that cooler temperatures are possible across interior parts of Trinidad, as well as in mountainous areas.
No significant rainfall is expected over the next 5 days as meteorological drought conditions intensify. Generally, less than 10 millimeters of rainfall is possible, favoring Northeastern Trinidad through the next 5 days, with less than 5 millimeters elsewhere.
Increased concentrations of Saharan Dust will be present in the atmosphere over the next 24 hours. Air quality levels will be reduced to moderate or unhealthy for sensitive groups at times. Saharan dust combined with already reduced air quality due to the prevalence of bush fires can further reduce air quality to unhealthy levels. Most of the dust is expected to diminish by Sunday afternoon.
