NWS Advisories in Effect for the Marianas

The National Weather Service (NWS), Guam Weather Forecast Office advise trade-wind swell will continue to produce hazardous seas, especially along east facing reefs.  The following advisories are in effect:


high risk of rip currents is in effect for Guam, Rota, Tinian, and Saipan through late tonight. 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.


The community is reminded to heed the advice of lifeguards, beach patrol flags, and signs. The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) advise residents and visitors to avoid east facing reefs and beaches until hazardous conditions subside.


small craft advisory remains in effect for Guam, Rota, Tinian, and Saipan coastal waters until 6 p.m. this evening. East winds of 10 to 20 knots with frequent gusts to 30 knots will produce hazardous conditions for operators of small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.


An airport wind advisory is in effect for the Guam International Airport until 6 p.m. this evening. Winds from the east-northeast near 18 knots with frequent gusts to 29 knots are expected.


GHS/OCD remind all residents and visitors to practice caution while traveling in these conditions; driving below the speed limit and allowing enough braking distance between vehicles.
