USVI and Puerto Rico Warned of Dangerous Seas and Strong Winds

The San Juan National Weather Service has issued an important decision support briefing, alerting to the dangers of hazardous seas and potentially fatal rip currents, which are expected to impact Puerto Rico and the U.S. Virgin Islands for the majority of the week.

This briefing describes a minor swell from the north to northeast moving across the regional waters. In combination with brisk easterly winds caused by a robust high-pressure system to the north, these conditions are expected to maintain hazardous maritime and surf zone environments until at least Tuesday.

The hazardous conditions are forecasted to last through the week and may extend into the weekend, driven by another long-period swell from the northeast and turbulent wind-driven seas. Additionally, the islands are likely to experience breezy conditions during the workweek.

Outlined Potential Risks and Impacts

• Marine Conditions: Waves are predicted to be treacherous, ranging from 6 to 10 feet, with occasional surges up to 11 feet. Wind velocities are anticipated to be between 15 and 25 knots, gusting up to 30 knots. These conditions present a considerable danger to small vessels. Consequently, Small Craft Advisories are in effect until at least Friday for most local waters, except for the coastal areas of south and southwestern Puerto Rico, where smaller crafts should proceed with caution.
• Surf Zone Dangers: Beaches facing the north and east in Puerto Rico, Culebra, Vieques, and the beaches of the U.S. Virgin Islands are under a High Rip Current Risk warning due to life-threatening swimming conditions and rip currents. This is a result of breaking waves ranging between 6 and 8 feet, occasionally higher.

Residents and tourists in these regions are encouraged to stay updated and practice safety near water bodies.
