1. Central Caribbean Sea:
Satellite imagery indicates that showers and thunderstorms have
increased and are showing signs of organization tonight with a
well-defined low pressure system located over the central Caribbean
Sea about 100 miles north-northeast of Curacao. Even though the
upper-level wind environment is currently only marginally favorable,
only a small additional increase in organization would result in the
formation of a tropical depression later today. The system is
expected to continue moving west-northwestward at 10 to 15 mph
across the central and western Caribbean Sea. Locally heavy
rainfall and gusty winds are likely to affect northwestern
Venezuela, the ABC island chain, and northeastern Colombia through
Friday. Interests in Jamaica, the Cayman Islands, and western Cuba
should closely monitor the progress of this system.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...90 percent.
