1. Near the Lesser and Greater Antilles:
Shower and thunderstorm activity has increased some in association with a tropical wave located roughly halfway between the Cabo Verde Islands and the Lesser Antilles.  Gradual development of this system is possible during the next couple of days while it moves westward to west-northwestward across the central tropical Atlantic.  Afterwards, conditions are expected to become more conducive for development and a tropical depression is likely to form by the early
to mid part of next week while the system approaches and then moves near or over the Lesser Antilles. The system is forecast to continue moving generally west-northwestward and could approach portions of the Greater Antilles by the middle to latter part of next week.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...high...80 percent.
