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

.SYNOPSIS...A surface trough, remnants of a frontal boundary,
extends from Puerto Rico to just S of Jamaica. This trough will
dissipate over the Caribbean waters today, but it will persist
near Puerto Rico through Mon. High pressure N of the area will
support fresh to strong NE to E winds near the coast of Colombia
at night beginning tonight, with seas building to 8 to 10 ft
during the period of the strongest winds. Otherwise, generally
moderate trade winds will persist across the Caribbean and
tropical Atlantic west of 55W through the middle of the week.

Synopsis for the the SW N ATLC including the Bahamas

.SYNOPSIS...A cold front extending over the SE waters from
22N62W to near Puerto Rico will shift slowly E and eventually 
dissipate NE of Puerto Rico on Mon. This front is associated to 
an occluded low pressure of 1012 mb spinning near 29N65W. High 
pressure will build off the U.S. east coast in the wake of the 
low through today, then continue E ahead of the next cold front 
expected to move off the NE Florida coast by this evening. 
Rapidly deepening low pressure along the front will support an 
area of gale force winds over the north-central waters on Mon 
night, with gale conditions possible Tue and Tue night, 
particularly N of 28N W of 72W. High pres will build across the 
SW N Atlantic, in the wake of the low, Wed and Thu.
