Weather Forecast (Next 24 Hours)
As of 10:00 AM Friday 3rd May 2019, isolated to scattered showers are moving across Trinidad, with heavy pockets remaining across Northern and Southern Trinidad. Locally, but brief, heavy rainfall and gusty winds are forecast. Heavier showers are likely to favour Eastern Trinidad. Across Tobago, partly cloudy skies and breezy conditions are occurring. Gusty winds up to 60 KM/H are possible, particularly in the vicinity of showers. Over the last 48 hours, several areas across T&T recorded gusts between 40-50 KM/H.
Throughout today into tonight, isolated to scattered showers are forecast to continue moving across mainly Trinidad. Heavier pockets are likely across Eastern and Southern parts of Trinidad. These showers are forecast to weaken as they progress westward. Gusty winds are likely in the vicinity of showery activity, up to 60 KM/H. These conditions are forecast to persist through the evening and into tonight. Across Tobago on the other hand, partly cloudy skies, with the odd isolated shower are forecast to interrupt a mostly settled but breezy day across the island.
These showers are due to two distinct surface to low-level shearlines across Trinidad and Tobago, with ample low-level moisture. Upper-level conditions remain unsupportive for enhancement of showers. As mentioned above, a few isolated heavy pockets may occur across parts of Eastern Trinidad, and accompanied by gusty winds.
Generally fresh to strong breeze is forecast (29-49 KM/H) for Friday mainly from the east. However, wind gusts in the range of high wind are possible (50-61 KM/H) across Trinidad and Tobago as the day progresses and the pressure gradient of the dominating high-pressure system tightens.
With wind gusts up to 60 KM/H, whole trees are expected to be in motion and there may be some inconvenience when walking against the wind gusts. Light outdoor objects may topple or become airborne such as garbage cans, loose galvanize or construction material and other outdoor furniture. Tents may jump.
Last night’s minimum temperatures were 24.7°C at Piarco, Trinidad and 25.8°C at Crown Point, Tobago.
Today’s maximum high temperatures across T&T are forecast to be near 31°C at Piarco, Trinidad and a heat index of 33°C. Across Tobago, maximum high temperatures are forecast to be near 30°C with a heat index of 32°C. The heat index is an index that combines air temperature and relative humidity, generating a “feel’s like” temperature.
Seas are forecast to remain moderate in open waters through the week. Waves in open waters are forecast to between 1.5 and 2.0 meters, occasionally up to 2.5 meters, particularly East of Trinidad and Tobago over the next 24 hours. In sheltered areas, seas are forecast to remain smooth, below 1.0 meters. Winds will be from the east through the next 5 days at 15-20 knots from the east.
