Winds and Seas Remain Hazardous for the Marianas; NWS Advisories in Effect

The National Weather Service (NWS), Guam Weather Forecast Office advise an east-northeast swell continues to affect the Marianas. The following advisories are in effect:


high surf advisory remains in effect for Guam, Rota, Tinian, and Saipan through Sunday afternoon, meaning high surf will affect beaches in the advisory area and will produce localized beach erosion and dangerous swimming conditions. Hazardous surf of 6 to 9 feet along north facing reefs near heights of 8 to 11 feet along east facing reefs is expected. Ritidian and Tarague Beaches are at most risk on Guam.


high risk of rip currents is in effect for Guam, Rota, Tinian, and Saipan through late Thursday night. Rip currents are powerful channels of water flowing quickly away from shore. 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 until 6 a.m. Thursday. Moderate to fresh trade winds with frequent strong gusts of 25 knots will continue through tonight. Combined seas of 8 to 10 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 the community to avoid north and east facing reefs and beaches until dangerous conditions subside and to heed the advice of lifeguards, beach patrol flags, and signs.
