Puerto Rico and the U.S. Virgin Islands Waters

909 PM AST Thu May 23 2024

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...
Surface high pressure across the central and northeast Atlantic and
an induced elongated trough just west of the region extending northwards
across the Mona passage, will promote moderate to fresh southeast winds
through Friday. In addition, the proximity of a deep layer trough close
to the Dominican Republic will aid in enhancing thunderstorm development
across portions of the regional waters and local passages through at least
Friday. Winds are forecast to diminish once again by Friday night and
over the weekend.
