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

.SYNOPSIS...A broad area of low pressure is along a tropical
wave located over the western Caribbean Sea with axis near 82W.
This system is producing disorganized showers and thunderstorms.
Environmental conditions appear to be conducive for gradual
development, and a tropical depression could form around the
middle part of this week while the disturbance moves slowly
west- northwestward. This system is then expected to move
northwestward into the Gulf of Mexico during the latter portion
of this week. Otherwise, gentle to moderate winds and slight to
moderate seas will persist across the basin through Fri.
