SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS
Winds are expected to diminish today as the surface high pressure moves eastward over the central Atlantic. This will result in subsiding seas and calm conditions across the local waters. Winds will once again increase by the end of the workweek into the weekend as a strong low pressure system develops over western Atlantic. This will promote moderate to fresh trade winds, resulting in choppy seas.
