400 AM AST Sun Jul 6 2025

.SYNOPSIS FOR PUERTO RICO AND THE U.S. VIRGIN ISLANDS WATERS...

Moderate easterly winds will prevail today, but local effects will
lead to choppy seas near coastal areas of northern Puerto Rico,
prompting small craft operators to exercise caution. Moderate to
locally fresh winds will return tonight and persist over the next few
days, expanding the area where caution is advised. Saharan dust will
keep skies hazy today, with another event expected later in the
workweek. Afternoon thunderstorms may affect coastal waters and local
passages, particularly near western Puerto Rico, each day. In
addition, tropical waves approaching Tuesday and Thursday will likely
increase the chances for showers, thunderstorms, gusty winds, and
locally higher seas.
