The National Weather Service (NWS) Guam Weather Forecast Office advised a long-period northwest and a northeast trade-wind swell will increase this evening causing surf to build along all but south facing reefs.
The following NWS advisories are in effect:
A high surf advisory will be in effect for Guam, Rota, Tinian, and Saipan from 6 p.m. this evening to 6 a.m. Thursday. Large breaking waves up to 10 are expected along north and west facing reefs. Surf is expected to fall Wednesday night into Thursday.
A high risk of rip currents will be in effect for Guam, Rota, Tinian, and Saipan from 6 p.m. this evening through Wednesday night. Dangerous rip currents are expected along north, east, and west facing reefs. Rip currents can sweep even the best swimmers away from the shore into deeper water. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. If caught in a rip current, do not swim against the current. Swim in a direction following the shoreline, face the shore and call or wave for help.
A small craft advisory will be in effect for the coastal waters of Guam, Rota, Tinian, and Saipan from 6 p.m. this evening to 6 a.m. Thursday. Northeast winds around 20 knots with gusts up to 30 knots and seas of 8 to 11 feet are expected. Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in hazardous conditions.
The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to avoid hazardous sea and surf, especially north, east, and west facing reefs and beaches. Heed the advice of lifeguards, beach patrol flags, and signs.
