.SYNOPSIS...Weak Atlantic high pressure will continue N of the
basin and support a weaker than usual pressure gradient over the
Caribbean basin throughout the week. Fresh to strong NE winds
will develop Tue night and Wed night across the Windward Passage
and in the lee of Cuba, associated with a late-season cold front
moving slowly across Cuba. The front is expected to dissipate

expected across the entire basin Fri and Sat.
