The National Weather Service (NWS), Guam Weather Forecast Office advise a large west-southwest swell will maintain hazardous surf and dangerous rip currents through Monday. The following advisories remain in effect for the Marianas:


high surf advisory is in effect for Guam, Rota, Tinian, and Saipan through Monday afternoon, meaning high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous conditions for swimmers and beach goers. Hazardous surf of 11 to 13 feet along south and west facing reefs will slowly subside over the weekend.


high risk of rip currents is in effect for Guam, Rota, Tinian, and Saipan through Monday afternoon. Rip currents are powerful channels of water flowing quickly away from shore. Dangerous rip currents are expected along south and west facing reefs through Monday. If caught in a rip current, yell for help. Remain calm and stay afloat while waiting for help. If swimming out of a rip current, swim parallel to shore and back toward the beach when possible. Do not attempt to swim directly against a rip current. Rip currents will be life threatening.


small craft advisory remains in effect for Guam, Rota, Tinian, and Saipan coastal waters through Saturday. Southwest winds of 15 to 20 knots and combined seas of 9 to 13 feet will produce hazardous conditions for operators of small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.


The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) advise residents and visitors to avoid hazardous seas over the weekend, especially south and west facing reefs and beaches, until conditions subside. Heed the advice of lifeguards, beach patrol flags, and signs.
