.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
A long period north-northeasterly swell will continue to move across
the local waters through this evening. An upper-level short-wave
trough will help to promote afternoon thunderstorms across the Mona
Passage and Caribbean waters. The remnants of the frontal boundary
will slowly dissipate across the western Atlantic through Friday,
when a surface high is expected to build over the region. This high
pressure will promote moderate trade winds from the upcoming weekend
into early next week.
