TYPHOON LUPIT [RAMIL/22W/0920]
T2K PUBLIC ADVISORY NUMBER 020

6:00 PM PST (10:00 GMT) Tue 20 October 2009

View: Advisory Archives (2004-2009)

  • Typhoon LUPIT (RAMIL) slowing down as it starts heading westward...currently undergoing an Eyewall Replacement Cycle (ERC)...no change in strength.

    *Residents and visitors along the Island of Luzon (particularly Northern Luzon) should closely monitor the progress of LUPIT (RAMIL).

    *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: LUPIT is expected to slightly decelerate and turn more westerly to WSW-ward w/in the next 12 to 24 hours. Its wind speed will slighty strengthen back to Category 3 (185 kph) as it moves closer to Northern Luzon due to improved atmospheric conditions (warm ocean moisture & unstable air). The 2 to 5-day Long-Range Forecast shows LUPIT approaching the northern coast of Cagayan on a WSW direction, as the High Pressure Steering Ridge building off China strengthens and steer the dangerous typhoon. LUPIT shall make landfall over Northern Cagayan on early Thursday evening Oct 22...passing very close to the north of Aparri between 8-9PM Thu. It shall cross Apayao and exit thru Ilocos Norte-Sur Area on Friday afternoon Oct 23, between 2-3PM...and over the South China Sea on Saturday morning, Oct 24. The typhoon shall turn westward while over the South China Sea, in the direction of Hainan Island-Vietnam Area on Sunday Oct 25. *Alternate Forecast Scenario: There is a possibility that LUPIT might track Westward passing thru the Balintang Channel and spare Cagayan & Ilocos Norte from a direct hit. This scenario is likely if the high pressure steering ridge located off Eastern China weakens. The probability of this alternate forecast still remains fair. Please be reminded that the Forecast Outlook changes every 6 hours, so a shift to the left or right of its future track and other conditions must be considered.

    + Effects: LUPIT's large circulation has become slightly stable. The eye remains cloud-filled as undergoes an Eyewall Replacement as shown on current satellite images. Its outer & inner rain bands remains at sea...not yet affecting any major islands at this time. LUPIT may begin to affect Northern Luzon tomorrow afternoon or evening (Oct 21) - if the forecast movement continues...deteriorating weather conditions expected. 1-day rainfall accumulations of 75 up to 200 mm (moderate to heavy rain) can be expected along its rainbands...with isolated accumulations of 400 mm or more (very heavy to extreme rain) near the center of LUPIT particularly along its projected path.

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

  • JTWC (US NAVY / AIR FORCE) 12, 24, 48 & 72 HR. FORECAST & REMARKS:

    2 AM (18 GMT) 21 OCTOBER: 20.2N 127.9E / 185-230 KPH (TY-Cat 3) / WSW @ 17 KPH

    REMARKS: 2 PM (06 GMT) TUE 20 OCTOBER POSITION: 20.4N 129.7E.
    *ANIMATED MULTISPECTRAL IMAGERY SHOWS TY
    22W'S EYE HAS ONCE AGAIN BECOME VISIBLE PINPOINTING ITS POSITION
    WITH HIGH ACCURACY. ANIMATED WATER VAPOR IMAGERY SHOWS THE SYSTEM
    HAS VERY GOOD RADIAL OUTFLOW ESPECIALLY ON THE POLEWARD SIDE THAT
    IS BEING ENHANCED BY THE STRONG UPPER-LEVEL WESTERLIES. UPPER AIR
    ANALYSIS INDICATES THE TYPHOON IS DIRECTLY UNDER THE RIDGE AXIS AND
    HAS DEVELOPED A MESOSCALE ANTICYCLONE. ADDITIONALLY, LOW VERTICAL
    WIND SHEAR HAS HELPED SUSTAIN ITS INTENSITY. THE CURRENT INTENSITY
    IS INTERPOLATED FROM THE DVORAK ESTIMATES FROM KNES (T5.5/6.0),
    PGTW (T5.0/5.0) AND RJTD (T4.5/4.5). TY 22W IS TRACKING ALONG THE
    SOUTHERN PERIPHERY OF A SUBTROPICAL STEERING RIDGE EXTENSION TO
    THE NORTH. IT IS IS EXPECTED TO CONTINUE TRACKING GENERALLY WESTWARD
    OVER THE NEXT 24 TO 36 HOURS IN THE CURRENT STEERING FLOW PATTERN.
    THEREAFTER, THE FLOW ASSOCIATED WITH A SUBTROPICAL RIDGE TO THE
    NORTHWEST IS EXPECTED TO PUSH THE TYPHOON ON A MORE EQUATORWARD
    TRACK. THIS FLOW WILL BRING TY 22W INTO NORTHERN LUZON BY TAU 60.
    INTERACTION WITH THE LANDMASS OF LUZON WILL CAUSE A SLIGHT WEAKENING
    BUT TY 22W SHOULD REINTENSIFY AFTER IT REEMERGES IN THE SOUTH CHINA
    SEA BY TAU 96 DUE TO WARM WATERS AND FAVORABLE UPPER LEVEL
    CONDITIONS. THE AVAILABLE NUMERIC GUIDANCE IS IN CLOSE AGREEMENT
    WITH THIS TRACK FORECAST. HOWEVER, THE WBAR AND TCLAPS SOLUTIONS
    DEPICT IMMEDIATE NORTHEASTWARD RECURVATURE INTO THE MIDLATITUDE
    WESTERLIES. GFS AND GFDN ALSO DO SOMETHING SIMILAR AT MID-RANGE...
