    + Forecast Outlook: OMAIS (AGATON) is expected to be downgraded into a Tropical Depression (TD) while moving slowly NNW-ward to Northward within the next 24 hours [2PM MAR 26: 17.5N 131.3E...about 1,020 km East of Tuguegarao City]. Increased upper-level winds (aka. Vertical Wind Shear) and lower Sea Surface Temperatures (SSTs) will continue to wrap into OMAIS' decaying circulation, letting it dissipate over the Northern Philippine Sea on early Saturday morning [2AM MAR 27: 18.7N 131.9E...about 1,055 ESE of Basco, Batanes]. There is also a possibility that the remnants of OMAIS, will be absorbed into the approaching Cold Front which is currently located off Taiwan. Please be reminded that the Forecast Outlook changes every 6 hours, so a turn to the left or right of its future track and other possibilities must be considered.

    + Effects & Hazards: OMAIS' rainbands remain over the ocean...no effects & hazards are in place. 6-hr total rainfall amounts of 5 up to 85 mm (light to moderate rain) can be expected along the its rainbands...with isolated amounts of up to 180 mm (heavy rain) situated along the northeastern periphery of OMAIS' (AGATON).

    + Current NE Monsoon Intensity: LIGHT >> Sunny to mostly cloudy skies with passing showers & rains can be expected along the following affected areas: NORTHERN & EASTERN BICOL REGION & NORTHERN SAMAR. Light to moderate NE winds (not in excess of 40 kph) can be expected along these areas. Large ocean waves of up to 8 to 10 feet along the beach-front areas of the affected areas are likely to occur beginning tomorrow until Monday.

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

  • JTWC (US NAVY / AIR FORCE) 12, 24, & 48 HR. FORECAST & REMARKS:

    2 AM (18 GMT) 26 MARCH: 16.3N 131.2E / 75-95 KPH (TS) / N @ 11 KPH 
    2 PM (06 GMT) 26 MARCH: 17.5N 131.3E / 55-75 KPH (TD) / NNE @ 13 KPH

  • REMARKS (for Meteorologists): 2 PM (06 GMT) THU 25 MARCH POSITION: 15.3N 131.5E.

    *THE LOW LEVEL CIRCULATION CENTER (LLCC) APPEARS TO BE BECOMING EXPOSED
    TO THE SOUTHWEST OF THE CENTRAL CONVECTION, BUT IT IS DIFFICULT TO ASSESS
    DUE TO CIRRUS OVERCAST AND FADING DAYLIGHT. NONETHELESS, A 250438Z AMSUB
    MICROWAVE IMAGE CONFIRMS THAT THE LLCC IS LOCATED NEAR THE SOUTHWESTERN
    QUADRANT OF THE CENTRAL CONVECTION, WHICH IS ALSO CONSISTENT WITH THE
    UPPER LEVEL PATTERN. VERTICAL WIND SHEAR HAS BEGUN TO ELEVATE ON THE
    NORTH SIDE OF THE CIRCULATION AND IS EXPECTED TO GRADUALLY WEAKEN THE
    SYSTEM OVER THE NEXT 36 HOURS AS AN UPPER LEVEL TROUGH ADVANCES
    DOWNSTREAM. THE INITIAL FORECAST INTENSITY IS C0NSISTENT WITH DVORAK
    INTENSITY ESTIMATES FROM PGTW AND RJTD RANGING FROM 35 TO 55 KNOTS.
    THE TS WILL TEND TO TRACK POLEWARD WITH THE TROUGH AS IT PUSHES
    DOWNSTREAM, BUT EXCESSIVE VERTICAL WIND SHEAR WILL LIKELY WEAKEN
    THE SYSTEM BEFORE ENTRANCE INTO THE MID-LATITUDES. THE MODEL CONSENSUS
    CONTINUES TO DEPICT A MORE AGGRESSIVE RECURVATURE, AS A RESULT, THE
    FORECAST IS SLOWER THAN AND TO THE WEST OF CONSENSUS, ACCOUNTING FOR
    DISSIPATION PRIOR TO RECURVATURE...
