  • Tropical Storm 23W (UNNAMED) has been christened as MIRINAE...moving quickly Northwestward farther away from the Marianas...may threaten Luzon, Philippines in 2 to 3 days.

    *Residents and visitors along the eastern coasts of Luzon & Visayas (Philippines) should closely monitor the progress of MIRINAE (23W).

    *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: MIRINAE's forecast outlook has changed slightly...now expected to continue tracking WNW within the next 1-2 days. It will reach Typhoon intensity early Thursday morning, as it enters the Philippine Area of Responsibility (PAR). The 2 to 5-day Long-Range Forecast shows the system turning more Westward late Thursday Oct 29 until Friday Oct 30th...and will be approaching the eastern coast of Luzon on Saturday morning, Oct 31 as a Category 3 Typhoon (195 kph) about more or less 300 km. North of Camarines Sur. The core will make landfall in between the towns of Baler & Casiguran in Aurora on late Saturday afternoon - crossing Central Luzon via Nueva Vizcaya, Tarlac, Pangasinan and Zambales during the night. It will exit the South China Sea on All Saint's Day, November 01. *Alternate Forecast Scenario (AFS): The latest ECMWF Extended Forecast issued at 8AM today, showed the system passing close just north of Camarines Norte and traversing Polillo Islands and making landfall over Northern Quezon, Nueva Ecija, Pampanga, and Zambales beginning Saturday afternoon until Sunday morning (Oct 30-Nov 01). This AFS track may happen if the High Pressure Steering Ridge off SE China and Taiwan strengthens more. 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 conditions must be considered.

    + Effects: MIRINAE's circulation has been improving over the past 12 hours. Its rainbands has left Marianas...improving weather conditions expected. As of now, this system has been moving across warm open waters of the Western Pacific Ocean. 6 to 12-hr total rainfall amounts of 2 to 50 mm (light to moderate rain) can be expected along its rainbands...with isolated amounts of 60 to 75 mm (moderate to heavy rain) near the center of Mirinae especially to the north.

    *THE CYCLONE HAS SINCE MOVED WEST OF THE MARIANAS
    ISLAND CHAIN AND HAS CONTINUED TO STRENGTHEN. DVORAK ESTIMATES FROM
    PGTW, KNES, AND RJTD SUPPORT A 30 TO 50 KNOT SYSTEM. A 062331Z ASCAT
    IMAGE SUPPORTS THE LOWER END OF THESE ESTIMATES WITH 35 TO 40 KNOT
    UNFLAGGED WINDS NEAR THE CENTER. THE INITIAL POSITION IS BASED ON
    RADAR FIXES FROM PHIK (USING PGUA RADAR), AS WELL AS POSITION FIXES
    FROM THE AGENCIES INDENTIFIED IN THE PREVIOUS SENTENCE. THERE HAS
    BEEN NO CHANGE IN THE FORECAST PHILOSOPHY SINCE THE PREVIOUS
    FORECAST. MODEL GUIDANCE IS STILL CLOSELY PACKED AROUND THE
    CONSENSUS, WITH THE EXCEPTION OF WBAR, WHICH CONTINUES TO BE A
    NORTHERN OUTLIER. THE STORM IS POSITIONED TO INTENSIFY STEADILY OVER
    THE NEXT FEW DAYS AS A TRANSITORY LONGWAVE TROUGH TO THE NORTH
    ENHANCES POLEWARD OUTFLOW. AS THIS TROUGH PULLS OUT OF THE TROPICS,
    THE MID-LEVEL SUBTROPICAL RIDGE WILL STRENGTHEN TO THE NORTH OF THE
    STORM, FACILITATING A GENERALLY WEST TO NORTHWESTWARD TRACK OVER THE
    NEXT 5 DAYS..
