The National Weather Service (NWS), Guam Weather Forecast Office has advised that winds associated with strong high pressure over the northwest Pacific will generate swell and seas that will produce hazardous surf through the coming week.

A high surf advisory is now in effect for Guam, Rota, Tinian, and Saipan until 6 p.m. Friday. Along north and east-facing reefs, hazardous surf of 10 to 12 feet will continue through much of the week.

A high risk of rip currents remains in effect for Guam, Rota, Tinian, and Saipan until 6 p.m. Friday. Rip currents are powerful channels of water flowing quickly away from shore. Strong and frequent rip currents are expected along north and east facing reefs and exposed beaches. 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 are life-threatening.

A wind advisory remains in effect until 7 p.m. this evening. East winds at 15 to 30 mph with gusts to 40 mph are expected. Strong winds can affect outdoor activities; plan accordingly. Take down items that can become airborne in heavier winds, and practice caution when driving high profile vehicles such as container trucks.

A small craft advisory remains in effect until 6 a.m. Wednesday, for the coastal waters of Guam, Rota, Tinian, and Saipan. East winds of 15 to 25 knots with occasional gusts to 35 knots are expected the next several days and could get even windier on Wednesday and Thursday. Combined seas of 8 to 10 feet will build further to between 10 to 12 feet tonight. The winds and seas will produce hazardous conditions for small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.

A thunderstorm advisory is now in effect for the Guam International Airport until 7 p.m. Expect winds from the east-northeast at 20 to 25 knots with gusts to 30 knots in and around showers.

The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) remind the community to avoid north and east-facing reefs throughout the week. Rip currents are life-threatening. Heed the advice of lifeguards, beach patrol flags, and signs.
