.Synopsis for Puerto Rico and the U.S. Virgin Islands Waters...
A frontal boundary lingering just north of the region is supporting
light to gentle northeasterly winds, while pulses of a long-period
northerly swell continue to spread across the Atlantic waters,
resulting in hazardous seas for small craft, particularly offshore.
This swell will gradually subside late in the week. As the boundary
weakens, surface high pressure drifting southeastward will promote a
gradual strengthening of winds, becoming moderate from the south over
the weekend. Another northerly swell is expected early next week. In
addition, remnant moisture from the frontal boundary may enhance
shower activity over the waters, with convection capable of producing
locally hazardous conditions.
