.SYNOPSIS...Winds will pulse to strong speeds near the northern 
coast of Hispaniola each night through Wed night. Otherwise,

northeastward portion of the area advances southward to near 27N.
The front will weaken into a trough by early on Mon as new high 
pressure begins to build southward over the forecast waters 
through Thu.
