Hazardous ocean conditions are expected through Monday, according to the National Weather Service Guam Office.
• A high surf advisory is in effect for Guam and the Marianas, producing localized beach erosion and dangerous conditions for swimmers and beachgoers. Hazardous surf of 11-13 feet along south- and west-facing reefs will slowly subside over the weekend.
• Rip currents will be life-threatening. A high risk of rip currents along souths and west-facing reefs is in effect for the region. Rip currents are powerful channels of water flowing quickly away from shore. If you’re caught in a rip current, remain calm, yell for help, and stay afloat while waiting for help to arrive. Don’t swim directly against a rip current — swim parallel to shore and back toward the beach when possible.
• A small craft advisory remains in effect for Guam, Rota, Tinian, and Saipan coastal waters through Sept. 13. Southwest winds of up to 23 mph and combined seas of 9-13 feet will produce hazardous conditions for operators of small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing.
The Offices of Guam Homeland Security and Civil Defense advise residents and visitors to avoid hazardous seas over the weekend until conditions subside.
