CHARLOTTE AMALIE — A combination of wind-driven seas and a long-period northerly swell will produce hazardous marine and coastal conditions during the next few days across the Atlantic waters, local Caribbean passages, northwest and northern coast of Puerto Rico, Culebra St. Thomas, and St. John, the National Weather Service said this afternoon.
Areas at Risk and Timing:
- For marine hazards:
* Small Craft Advisories are in effect across the Atlantic waters and local Caribbean passages through at least Thursday afternoon.
- For coastal hazards:
- There is a High Risk of Rip Currents along the northern coast of Puerto Rico, Culebra, St. Thomas, and St. John until Thursday afternoon due to breaking waves around 5 to 7 feet and occasionally higher, increasing to 10 to 12 feet from this evening through Wednesday.
- A High Surf Advisory is in effect along the northern coast of Puerto Rico, Culebra, St. Thomas, and St. John from this evening through Wednesday afternoon due to breaking waves up to 10 to 12 feet.
Hazards & Potential Threats/Impacts:
- Small Craft Advisory: Hazardous seas impacting small crafts.
- High Rip Current Risk: Rip currents with the potential to pull even experienced swimmers away from shore.

Localized beach and dune erosion, along with dangerous swimming conditions are likely. Localized minor flooding and damage to beachfront structures is possible.
