Presently, isolated showers are affecting the Southern half of Trinidad, mainly eastern and central parts of the island. Cloudy conditions are occurring elsewhere, with upper level cirrostratus clouds moving across T&T. Isolated showers are forecast overnight with several low-level cloud patches East of T&T, generally moving west to northwest.
Over the next several days, through Tuesday, Trinidad and Tobago will generally be experiencing similar daily weather. Mostly settled conditions will be interrupted by low-level cloud patches, bringing partly to mostly cloudy skies and the odd isolated shower. There are increased chances for showers across Southern and Eastern Trinidad, as well as hilly areas over the next 24 hours due to winds from the east-southeast.
This is due to a mid level low pressure to the north of Puerto Rico, weakening the dominating high pressure system’s influence over the region. It will also allow for the advection of upper level moisture and weak instability from the south, creating occasional cloudiness and a few showers over the weekend. No significant rainfall is forecast.
The dominating weather feature, however, is the weak surface to low-level high pressure system, in the Eastern Atlantic. Surface to low-level convergence, on the southwestern periphery of the ridge (high pressure), will aid in the development of occasional cloudiness and isolated showers, mainly during the early morning and late evening over the next several days.
Very little rainfall accumulations are forecast over the next several days, with up to 5 millimeter accumulations, daily, across both Trinidad and Tobago.
Winds are forecast to be gentle, generally less than 30 KM/H, with gusts up to 40 KM/H at times.
Minimum low temperatures across Trinidad and Tobago over the next 3 days are forecast to range between 24°C-26°C. Low temperatures are likely to be lower across inland and mountainous areas. Last nights minimum temperatures were 24.2°C at Piarco, Trinidad. At Tobago, the minimum low temperature was 26.0°C at Crown Point.
Maximum high temperatures across Trinidad are forecast to be warm, near 32°C. Across Tobago, maximum high temperatures are forecast to near 30°C over the next 3 days. Today’s maximum high temperatures were 31.7°C at Piarco, Trinidad and 30.6°C at Crown Point, Tobago.
The maximum high heat index, or “feel’s like” temperature is forecast to generally remain near a hot 35°C during the early to mid-afternoons of Trinidad and 34°C in Tobago.
Seas are forecast to remain moderate in open waters through the week. Waves in open waters are forecast to remain up to 1.5 meters, occasionally up to 2.0 meters particularly East of Trinidad and Tobago. In sheltered areas, seas are forecast to remain smooth, below 1.0 meters. Winds are forecast to be from the east to southeast at 10-15 knots.
No Saharan Dust In Sight
Dust concentrations are at negligible levels across the Southern and Eastern Caribbean. In fact, most places across the Eastern Caribbean are presently experiencing good air quality. Air quality is forecast to remain at good levels for the next several days. Areas in the immediate vicinity of bushfires may experience moderate air quality.
At moderate air quality levels, unusually sensitive groups should consider reducing prolonged or heavy exertion.
Thankfully, long range dust models aren’t indicating any major intrusions of Saharan Dust over the next 10 days!
