    + Forecast Outlook: NIDA is expected to drift slowly northeastward and will start weakening within the next 2 days. It will pass due south of Iwo To Monday afternoon (2PM Nov 30: 22.0N 141.6E). The 3 to 4-day Medium-Range Forecast shows the system downgraded to a Tropical Storm upon entering the mid-latitude westerly windflow (westerlies) & accelerate slightly ENE-ward on Tuesday afternoon (2PM Dec 01: 23.5N 143.5E)...about 265 km SE of Iwo To. NIDA will continue to move ENE across the open seas of the Western Pacific Ocean and become Extratropical by Wednesday afternoon (2PM Dec 02: 25.7N 148.9E). Based on this forecast, this system will not enter the Philippine Area of Responsibility (PAR). However, constant watch on this system will continue as half of the forecast guidance models still shows a track towards the Philippine Sea. *Alternate Forecast Scenario (AFS): The latest UKMO, JGSM, GFS, and ECMWF Extended Forecasts issued at 8AM today (Nov 28), still predicts NIDA to turn towards the left into the Philippine Sea - on a West or WSW track due to an approaching surge of NE Monsoon (aka. locally as "Amihan") from the strong High Pressure Area off SE China. This scenario is likely if the trend continues. Stay tuned for more info. 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: NIDA still over open seas and remains a large and dangerous super typhoon. This howler is not affecting any major islands at this time. 6-hr total rainfall amounts of 5 up to 150 mm (light to moderate rain) can be expected along the outer and inner bands...with isolated amounts of 250 mm (heavy rain) near the center or EyeWall of Nida.

    + Current NE Monsoon Intensity: LIGHT >> Sunny, clear to cloudy skies with possible passing rains, squalls (subasko) can be expected along the following affected areas: PORTIONS OF NORTHERN AND EASTERN LUZON, BICOL REGION, QUEZON, MASBATE, & NORTHERN VISAYAS. Light to moderate northeasterly winds (not in excess of 35 kph) can be expected on these areas.

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

    REMARKS: 2 PM (06 GMT) SAT 28 NOVEMBER POSITION: 19.1N 139.3E.

    *ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)
    SHOWS THAT STY 26W HAS BEEN ALMOST STATIONARY FOR THE PAST 9 HOURS,
    WITH A NOTICEABLE WOBBLE OBSERVED IN THE MSI. MODEL GUIDANCE REMAINS
    IN POOR AGREEMENT WITH JGSM, ECMWF, UKMO AND GFS SHOWING A WESTWARD
    TRACK. WBAR, TC-LAPS, GFDN AND NGPS MAINTAIN A RE-CURVE FORECAST.
    NGPS HAS PERSISTED WITH EXCESSIVE TRACK SPEEDS AND ERRONEOUS INTEN-
    SITY VALUES OUT TO 120 HOURS. THE FORECAST REASONING HAS NOT SHIFTED
    FROM THE PREVIOUS FORECAST, KEEPING THE CURRENT TRACK SPEEDS SLOW
    THROUGH 48 HOURS, INCREASING SPEED BEYOND 48 HOURS AS STY 26W MOVES
    SLOWLY NORTHWARD AROUND THE WESTERN EXTENT OF THE MID-LEVEL SUB-
    TROPICAL RIDGE (STR). THE STR IS EXPECTED TO BUILD SLOWLY WESTWARD
    TO PROVIDE THE STEERING SUPPORT IN THE LATER TAUS. A 280426Z AMSR-E
    IMAGE SHOWS THAT THE INNER EYEWALL CONTINUES TO WEAKEN WHILE THE
    SECONDARY EYEWALL IS BEGINNING TO CONSTRICT INWARD. DVORAK ESTIMATES
    FROM PGTW AND RJTD REFLECT A SLIGHT DECREASE IN INTENSITY OVER THE
    PAST 6 HOURS, BRING THE CURRENT INTENSITY TO 145 KNOTS. THE FORECAST
    REMAINS CONSISTENT WITH A SLOW WEAKENING TREND AS STY 26W MOVES INTO
    A LESS FAVORABLE ENVIRONMENT, WITH INCREASING VERTICAL WIND SHEAR AND
    DECREASING OCEAN HEAT CONTENT/SEA SURFACE TEMPERATURES...
