Surf will remain hazardous at 8 to 11 feet along south facing reefs and 11 to 14 feet along west facing reefs. Avoid venturing out along south and west facing reefs and beaches. Large breaking waves can knock people down and cause serious injuries. Strong 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, meaning wind speeds and heavy seas are expected to produce wave conditions hazardous to small craft. Southwest winds of 19 to 29 mph with occasional gusts to 39 mph are expected. Seas of 10 to 12 feet will continue through Thursday. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.
