Synopsis for Caribbean Sea and Tropical N Atlantic from
07N to 19N between 55W and 64W

.SYNOPSIS...A tropical wave over the eastern Caribbean along 62W
continues to show signs of organization, and it will likely
become a tropical depression within the next couple of days. The
disturbance is forecast to move west-northwestward toward the
central Caribbean Sea later this week. Interests in the Windward
Islands should closely monitor the progress of this system as
heavy rainfall and gusty winds are affecting these islands.
Regardless of development, heavy rainfall is forecast to affect
northwestern Venezuela, northeastern Colombia, and the ABC
island chain later this week. An Air Force Reserve
reconnaissance aircraft is scheduled to survey the system this
evening.
