The National Weather Service (NWS), Guam Weather Forecast Office continue to monitor a number of potential major weather features in the region.
NWS is closely monitoring a tropical disturbance, Invest Area 94W, centered near Pohnpei, which is expected to gradually develop as it continues west north-west toward the Marianas the next couple of days. On its current track, 94W is expected to pass near or south of Guam late Tuesday or very early Wednesday morning. There is still uncertainty as to whether it will remain a disturbance or intensify as it makes its way near.
A second circulation is found east of Majuro. At this time, it is weak and disorganized but will continue to be monitored as it tracks westward.
The Offices of Guam Homeland Security and Civil Defense (GHS/OCD) advise the community to prepare for the onset of heavier winds, expected as early as Tuesday, by taking the following basic precautionary actions now:
Clear loose debris around your yard and store any items that may become airborne with heavy winds, such as canopies, tarps or trampolines;
- Stay up to date with the latest information and advisory updates;
- If planning outdoor activities, have alternate plans in place;
- Avoid the ocean throughout the week. Rip currents are life threatening;
- Heed the advice of lifeguards, beach patrol flags, and signs.
The following NWS advisories are in effect:
A high surf advisory remains in effect for Guam, Rota, Tinian, and Saipan until 6 p.m. next week Tuesday. Along north and east facing reefs, hazardous surf of 10 to 14 feet today could possible build to between 15 and 20 feet by Tuesday. Do not venture out along north and east facing reefs and beaches. Large braking waves can knock you down and cause serious injuries.
A high risk of rip currents is also in effect for Guam, Rota, Tinian, and Saipan through the coming weekend. 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 small craft advisory remains in effect until 6 a.m. Tuesday, 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 through tonight and will likely build to between 20 and 30 knots with frequent gusts to 40 knots Tuesday through Wednesday. Combined seas of 9 to 11 feet will build further to between 10 to 12 feet tonight and even higher on Tuesday. The winds and seas will produce hazardous conditions to small craft. Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions.
A gale watch will then be in effect from Tuesday morning through late Thursday night. A gale watch is issued when the risk of gale force winds or frequent gusts of 38 mph to 51 has significantly increased but the specific timing and location of gale force winds is still uncertain.
A hazardous seas watch will be in effect from Tuesday morning through late Thursday night. A hazardous seas watch is issued when the risk of hazardous seas of 15 mph or more has significantly increased but the specific timing and location is still uncertain. The gale watch and hazardous seas watch are intended to provide additional lead time for mariners who may wish to consider altering plans.
A wind advisory will be in effect for Guam, Rota, Tinian, and Saipan from 6 a.m. Tuesday to 6 p.m. Wednesday. Very windy conditions will begin Tuesday morning, probably a few hours before sunrise. Winds of 25 to 35 mph are expected. Winds this strong can damage less substantial structures and make driving difficult, especially for high profile vehicles.
