    + Forecast Outlook: URDUJA is expected to slow down and will remain quasi-stationary for the next 12 to 24 hours as it interacts to the much stronger TS NIDA (26W), located South of Guam. The 2 to 5-day Long-Range Forecast shows the system undergoing a counter-clockwise loop passing over Northeastern Mindanao tomorrow (2PM Nov 25: 9.2N 125.5E)..and will exit off the east coast of Surigao del Sur as a minimal Tropical Storm on Thursday morning (2AM Nov 26: 8.9N 126.1E). URDUJA will start tracking ENE to NE-ward towards NIDA (26W) starting Friday [2AM Nov 27: 9.1N 127.4E) and strengthen into a 85-kph tropical storm. This forecast outlook remains poor in predicting the future path of URDUJA...various computer guidance model are having a hard time positioning this system. 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: URDUJA's rainbands has been sheared to the west and continues to dump scattered to widespread rains across Northern Mindanao and the whole of the Visayas. Rainfall amounts of up to 200 mm (heavy rains) can be expected within the heavy rainbands of this depression. Residents in low-lying areas & steep slopes must remain alert & seek evacuation for possible life-threatening flash floods, mudslides & landslides due to the anticipated heavy rains brought about by this system. Precautionary measures must be initiated if necessary.

    [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 AM (18 GMT) TUE 24 NOVEMBER POSITION: 10.1N 126.0E.
    *ANIMATED INFRARED SATELLITE IMAGERY INDICATES WEAKENING CONVECTIVE
    BANDING OVER THE WESTERN SEMI-CIRCLE DUE TO INTERACTION WITH LAND
    AND WEAK TO MODERATE EASTERLY VERTICAL WIND SHEAR. AMSU IMAGE INDICATED
    A DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH CONVECTIVE BANDING
    WRAPPING FROM THE NORTHWEST TO THE SOUTHWEST QUADRANT. THERE IS FAIR
    CONFIDENCE IN THE CURRENT POSITION BASED ON THE PARTIALLY-EXPOSED LLCC
    USING LOWER RESOLUTION MICROWAVE IMAGERY. THE CURRENT INTENSITY IS
    ASSESSED AS SLIGHTLY LOWER THAN THE DVORAK ESTIMATE OF 35 KNOTS (PGTW)
    BASED ON THE WEAK BANDING. TD 27W IS FORECAST TO BEGIN TRACKING EAST-
    WARD TO EAST-NORTHEASTWARD AFTER TAU 36 AND IS FORECAST TO APPROACH
    WITHIN 600NM OF TS 26W AT 120 HRS. THEREFORE, TD 27W IS EXPECTED TO INTERACT
    WITH TS 26W, WHICH WILL DRIVE A CYCLONICALLY-CURVED TRACK TOWARD TS
    26W. THE AVAILABLE NUMERICAL GUIDANCE IS SPARSE BUT SUPPORTS THIS
    SCENARIO. THE SYSTEM IS NOT EXPECTED TO INTENSIFY UNTIL IT TRACKS
    BACK OVER WATER NEAR TAU 48 AND IS FORECAST TO REACH MINIMAL TS
    STRENGTH UNDER MARGINAL CONDITIONS...
