.Synopsis for Puerto Rico and the U.S. Virgin Islands Waters...
Hazardous marine conditions will persist through at least tonight as
a strong high-pressure system over the Atlantic maintains moderate
to fresh southeasterly winds. Therefore, expect confused seas
particularly across Atlantic waters and local passages throughout the
day. Conditions are expected to improve starting early Tuesday
morning, with seas subsiding to around 5 feet in the Atlantic and up
to 4 feet in the Caribbean. While trade wind showers continue to
drift across the region, isolated to scattered thunderstorms are
likely this afternoon, especially over coastal waters near western,
northern, and northwestern Puerto Rico. Expect shower and
thunderstorm coverage to increase slightly later this week as a
series of troughs interacts with deep tropical moisture.
