Fresh to strong trade winds are projected to strengthen further today, Tuesday, due to a weather disturbance passing south of Guam.
At the same time, a strengthening ridge of high pressure north of Guam is expected to create an even tighter pressure gradient. This increased force will briefly drive the winds even higher.
A wind advisory is in effect from 6am today to 6pm Wednesday. That means winds of 35 mph are expected. Winds this strong can damage less substantial structures and make driving difficult, especially for high profile vehicles. Use extra caution.
This will also result in hazardous marine conditions this week.
A gale watch remains in effect from today morning through late Thursday night Hazardous seas watch remains in effect from Tuesday morning through late Thursday night.
A small craft advisory means that wind speeds of 22 to 33 knots are expected to produce wave conditions hazardous to small craft.
Based on information received from the National Weather Service in Tiyan, Guam, and compiled at the CNMI Emergency Operations Center-State Warning Point, very windy conditions will begin this morning, probably a few hours after sunrise. Winds of 25 to 35 mph will gradually shift from northeast today through east tonight to southeast tomorrow.
Loose outdoor objects could be blown away. Canopies, tarps, and tents could be damaged.
Inexperienced mariners, especially those operating smaller vessels should avoid sailing or boating in these conditions.
A hazardous seas watch is issued when the risk of hazardous seas of 15 feet or more has significantly increased but the specific timing and/or location is still uncertain. It is intended to provide additional lead time for mariners who may wish to consider altering their plans.
A gale watch is issued when the risk of gale force winds or frequent gusts of 34 to 47 knots has significantly increased but the specific timing and/or location is still uncertain.
Inexperienced mariners, especially those operating smaller vessels, should avoid sailing in these conditions. (Saipan Tribune)
