MESSAGE: Tropical Storm Warning Issued for Barbados, Grenada and its Dependencies and Trinidad & Tobago. A Severe Weather Warning has been issued for sections of Guyana and Flash Flood Watch in effect for four (4) Parishes in Jamaica


The Caribbean Disaster Emergency Management Agency (CDEMA) and the Caribbean Institute for Meteorology and Hydrology (CIMH) have been monitoring an area of interest east south-east of the southern Windward Islands over the past 72 hours.


On Sunday 18th June 2017, The Caribbean Institute for Meteorology and Hydrology provided an updated brief on a tropical wave about 800 miles east-southeast of the southern Windward Islands. This system is forecast to move to the west-northwest at near 20 mph towards the Windward Islands and northeastern South America during the next two days. Heavy rains and gusty winds associated with this system are likely to spread over portions of the Windward Islands Monday night and Tuesday.

* Formation chance through 48 hours...medium...60 percent.
* Formation chance through 5 days...medium...60 percent.

The CIMH weather briefing also advised of surface observations and satellite data indicating that a broad low pressure area is centered near the east coast of the Yucatan Peninsula. This system is producing a large area of showers and thunderstorms along with winds to gale force several hundred miles to the east and northeast of the center. However, the low lacks a well-defined center of circulation. Gradual development is expected while the low moves slowly north-northwestward across the Yucatan Peninsula through tonight, and then over the southern or central Gulf of Mexico on Monday and Tuesday, where a tropical or subtropical cyclone is likely to form. Regardless of development, heavy rains are expected over portions of Central America, the Yucatan Peninsula, Jamaica, the Cayman Islands, and western Cuba during the next several days.

* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.
