The National Weather Service (NWS), Guam Weather Forecast Office advise large north swell will produce dangerous surf along north facing shores. The following advisories are in effect:
A high surf warning is in effect for north facing reefs of Guam, Rota, Tinian, and Saipan until 6 p.m. Wednesday, meaning dangerous, battering waves will pound the shoreline, resulting in life-threatening conditions. Dangerous surf at 12 to 16 feet along north facing reefs, between 9 and 12 feet along west facing reefs, and 8 to 11 feet along east facing reefs is expected through Wednesday.
A high surf advisory is in effect for Guam, Rota, Tinian, and Saipan from 6 p.m. Wednesday to 6 p.m. Thursday, meaning high surf will affect beaches in the advisory area and will produce localized beach erosion and dangerous swimming conditions. Hazardous surf of 8 to 10 feet along north facing reefs and as high as 10 feet along east facing reefs is expected.
A 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.
A small craft advisory remains in effect for Guam, Rota, Tinian, and Saipan coastal waters until 6 p.m. Thursday. Northeast winds at 15 to 25 knots and combined seas of 10 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 the community to avoid the waters until dangerous conditions subside and to heed the advice of lifeguards, beach patrol flags, and signs.
