The Eastern Caribbean Forecast valid up to 8am Wednesday 20th June 2018.

Weather Synopsis: An active tropical wave interacting with an environment conducive for favorable development will continue to result in cloudy skies, showers, some of which could become moderate to heavy at times, and possible thunderstorms across the southern Windward Islands, mainly today, and Trinidad and Tobago, today and tonight, as it exits the area. As the wave moves westward, interaction with a mid to upper level trough located near Puerto Rico will result in similar weather conditions from Puerto Rico to The British Virgin Islands and to a lesser extent St. Kitts/ Nevis and Anguilla. Elsewhere and otherwise, the high pressure system will dominate, keeping shower activity to a minimum, with at most a moderate chance of showers expected.

Winds: Southeasterly across the Leeward Islands to Puerto Rico with speeds ranging between 15 to 30 km/h or 8 to 16 knots and easterly across the rest of the Eastern Caribbean with speeds ranging between 19 to 33 km/h or 10 to 18 knots. However, across Trinidad and Tobago a lighter flow of 6 to 13 km/h or 3 to 7 knots is expected and could also become variable or calm at times.

Seas: Moderate with significant wave heights of 1.2 to 1.8 metres or 4 to 6 feet.
