  • Tropical Storm 18W (UNNAMED) to pass near Guam any moment from now...Gale-force winds w/ rains expected.

    *Residents and visitors along the Marianas should closely monitor the progress of 18W (UNNAMED).

    *Kindly refer to your local warnings & bulletins issued by your country's official weather agency. This advisory is intended for additional information purposes only.


    + Forecast Outlook: 18W is expected to remain a weak system as it passes very close to Guam. The 2 to 3-day Medium-Range forecast shows the system dissipating and being absorbed into the circulation of Typhoon PARMA, which is a much stronger system.

    + Effects: 18W's circulation remains small. This system will bring light to moderate rainfall w/ gale-force winds (30-60 kph) across the Marianas today.

    [Important Note: Please keep in mind that the above forecast outlook, effects, current monsoon intensity, & tropical cyclone watch changes every 6 to 12 hrs!]
