    + Forecast Outlook: NIDA is expected to continue losing strength and slow down further as it turns northward within the next 2 days. The 3 to 5-day Long-Range Forecast shows the system weakening to a Category 2 and will begin to recurve sharply towards the NE by Sunday afternoon (2PM Nov 29: 22.2N 140.4E)...about 1,950 km East of Taiwan or 305 km SSW of Iwo To. NIDA will accelerate ENE-ward on Monday (2PM Nov 30: 25.5N 144.7E)...and will be downgraded into a Tropical Storm as increasing upper-level winds (aka. Vertical Wind Shear) and lower sea surface temperatures (SSTs) affects its circulation and start transitioning into an Extratropical Cyclone Tuesday afternoon (2PM Dec 01: 29.8N 153.1E). Based on this forecast, this system is not forecast to enter the Philippine Area of Responsibility (PAR). *Alternate Forecast Scenario (AFS): Less than half of its cluster of forecast models are showing NIDA to turn towards the left...tracking it towards the Philippines on a West to WSW motion due to an approaching High Pressure Ridge off China. This scenario remains poor at this time. 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's southeastern outer rainbands still spreading across Marianas including Guam & Saipan, bringing passing rains with squalls across the area. 6-hr total rainfall amounts of 5 up to 100 mm (light to moderate rain) can be expected along the outer and inner bands...with isolated amounts of 200 mm (heavy rain) near the center of Nida. Click here to view the latest NOAA's eTRaP graphic on the storm's rainfall amount. Possible coastal Storm Surge flooding of 9 to 12 feet above normal tide levels...accompanied by large and dangerous battering waves...is possible along the coastal areas of Marianas including Guam & Saipan. Extensive damage is likely on this type of storm surge.

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

    *SUPER TYPHOON (STY) 26W (NIDA), LOCATED APPROXIMATELY 300 NM WEST-
    NORTHWEST OF GUAM, HAS TRACKED NORTHWESTWARD AT 10 KNOTS OVER THE
    PAST SIX HOURS. THOUGH STY NIDA STILL HAS A WELL-DEFINED 20-NM EYE,
    ANIMATED INFRARED IMAGERY SHOWS CLOUD TOPS ASSOCIATED WITH THE DEEP
    CONVECTION HAVE STARTED TO WARM AND THE OVERALL CONVECTIVE STRUCTURE
    HAS BECOME MORE ASYMMETRICAL AS THE GREATEST EXTENT OF DEEP
    CONVECTION HAS STARTED TO SHIFT TO THE WEST OF THE SYSTEM CENTER.
    ACCORDINGLY, THE SYSTEM HAS WEAKENED SLIGHTLY OVER THE PAST SIX
    HOURS AND THE CURRENT INTENSITY IS BASED ON A COMBINATION OF DVORAK
    ESTIMATES FROM PGTW (140 KTS) AND RJTD (155 KTS). UPPER-LEVEL
    ANALYSIS INDICATES THE SYSTEM CONTINUES TO HAVE AN ANTICYCLONE ALOFT
    WHICH IS PROVIDING STRONG RADIAL OUTFLOW. STY NIDA WILL CONTINUE TO
    TRACK NORTHWESTWARD AND GRADUALLY SLOW IN FORWARD TRACK SPEED AS IT
    APPROACHES THE SUBTROPICAL RIDGE AXIS. AFTER 48 HRS, THE SYSTEM
    SHOULD CREST THE RIDGE AXIS AND START TO ACCELERATE INTO THE MID-
    LATITUDES WHILE GRADUALLY WEAKENING DUE TO INCREASED VERTICAL WIND
    SHEAR. BY 120 HRS, STY NIDA IS EXPECTED TO BEGIN EXTRATROPICAL
    TRANSITION...
