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

.SYNOPSIS...Large NE swell will impact the tropical Atlantic
waters through Sat. A low pressure system will deepen across the
NW Atlc through the weekend and produce a large N swell that 
will penetrate the NE Caribbean Passages Sun through late Wed, 
reaching the A-B-C Islands and coastal Venezuela. The low will 
drag a cold front into the northern Caribbean Sat night, 
gradually dissipating through early next week.
