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

.SYNOPSIS...Strong high pres across the NW Atlc will dominate
the region as it settles across the Bermuda area through the end
of the week. Fresh to strong tradewinds will prevail across the
Caribbean and Tropical N Atlc waters through Thu, with nocturnal
winds pulsing to gale force winds off of Colombia. High pres
will weaken through the weekend, leading to diminishing winds
and seas.
