  • The strong tropical disturbance (LPA/94W) north of Chuuk Island has strengthened into Tropical Depression 22W (UNNAMED)...moving quickly westward...threatens Guam and Southern Marianas.

    *Residents and visitors along the Mariana Island Chain should closely monitor the progress of 22W.

    *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: 22W is expected to continue moving quickly Westward, within the easterly flow of the strong high pressure north of it. It shall become a Tropical Storm tomorrow morning before passing to the south of Guam. The 3 to 5-day Long-Range Forecast shows 22W heading slightly WNW across the Western Pacific Ocean...and shall become a Category 1 Typhoon as it nears the Philippine Area of Responsibility (PAR) on Monday Oct 19. *The ECMWF 10-Day Extended Long-Range Forecast: 22W is expected to slow down as it approaches the Island of Luzon on Tuesday Oct 20, intensifying into a Category 3 or 4 Typhoon...It shall make landfall over Northern Luzon or over Isabela Wednesday evening, Oct 21 and exit thru Benguet and La Union early Thursday morning, Oct 22. Please be reminded that the ECMWF model run changes every 12 hours, so a shift to the left or right of its future track and other conditions must be considered.

    + Effects: 22W's broad circulation continues to consolidate while moving Westward. Its outer bands is expected to move into Southern Marianas beginning tonight - bringing scattered rains w/ squalls and thunderstorms. 1-day rainfall accumulations of 50 up to 100 mm (moderate to heavy rain) can be expected along PARMA's rainbands...with isolated accumulations of up to 200 mm (very heavy rain) near the center of 22W particularly along its projected path. 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.

    + Tropical Cyclone Watch:

    (1) Tropical Disturbance 93W (LPA) has accelerated WNW across Leyte and is now over the Visayan Sea, just south of Masbate...its rainbands ahead of its center, continues to spread across the whole of the Visayas, Bicol Region and Southern Luzon including Metro Manila...currently located near lat 11.5N lon 124.0E...or about 100 km SE of Masbate City...with 1-min maximum sustained winds of 30 kph near the center...moving WNW @ 28 kph towards Romblon & Mindoro area. This system may likely become a Tropical Cyclone once it reaches the South China Sea tomorrow.

    *TD 22W HAS CONSOLIDATED QUICKLY OVER THE PAST 12
    HOURS WITH IMPROVED CONVECTIVE BANDING OVER THE SOUTHERN SEMI-CIRCLE
    AS INDICATED IN RECENT ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI)
    AND MICROWAVE IMAGERY. A 132118Z SSMIS 37 GHZ IMAGE DEPICTS
    CURVED CONVECTIVE BANDING WRAPPING INTO THE SOUTHEAST QUADRANT OF
    THE LOW-LEVEL CIRCULATION CENTER (LLCC) WITH STRONG DEEP CONVECTION
    ALIGNED NORTH-SOUTH OVER THE WESTERN SEMI-CIRCLE. A 131944Z QUIKSCAT
    SHOWED 40-50 KNOT UNFLAGGED WINDS, HOWEVER, THESE WINDS WERE LOCATED
    UNDER THE INTENSE CONVECTION AND WERE CONSIDERED SUSPECT. SURFACE
    OBSERVATIONS FROM TRUK, APPROXIMATELY 150 NM SSW OF THE CENTER
    INDICATED ONLY 10-KNOT WESTERLIES AND SLP NEAR 1010 MB SUPPORTING
    THE TD CLASSIFICATION. THE CURRENT INTENSITY IS BASED ON DVORAK
    ESTIMATES FROM KNES AND PGTW RANGING FROM 25 TO 30 KNOTS. THE
    CURRENT POSITION IS BASED ON THE LATEST PGTW SATELLITE FIXES AS
    WELL AS THE AFOREMENTIONED MICROWAVE IMAGERY WITH FAIR
    CONFIDENCE...
