Possible Impacts
Mariners should generally exercise caution during heavy showers or thunderstorms, as seas may become locally rough or choppy in their vicinity, mainly due to gusty winds.
On Saturday and Sunday, a short-lived, long-period swell event is forecast to bring occasional battering waves along the northern coastlines of both islands. Marine interests should also exercise caution.
Rip currents always pose a hazard on the nation’s beaches. If caught in a rip current, swim perpendicular to the current (parallel to the shore). Mariners, especially small craft operators, should ensure their vessels are securely anchored or docked, as choppy/breaking wave conditions may drag the vessel onto the ocean floor or reefs in shallow waters or even break anchorage/mooring.
