SUPER TYPHOON LUPIT [RAMIL/22W/0920]
T2K PUBLIC ADVISORY NUMBER 017

View: Advisory Archives (2004-2009)

  • Super Typhoon LUPIT (RAMIL) weakens a bit as it turns WNW...still an extremely dangerous Category 4 system w/ winds of 240 km/hr...threat to Northern Luzon continues.

    *Residents and visitors along the Island of Luzon (Northern Philippines) 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 start accelerating and turning more westerly w/in the next 12 to 24 hours. Its wind speed will continue to decrease as it moves closer to Northern Luzon. The 2 to 5-day Long-Range Forecast shows LUPIT moving into a WSW direction, as the High Pressure Steering Ridge building off China strengthens and extends across Ryukyu & Okinawan Islands. This ridge will steer LUPIT into Extreme Northern Luzon...making landfall over Northern Cagayan between 2 to 4 PM on Thursday Oct 22...passing directly or very close to Aparri. The core (eye & eyewall) of LUPIT shall cross Abra, Kalinga and exit over Ilocos Sur Thursday evening and shall be over the South China Sea Friday, Oct 23 - turning West to WNW towards Hainan Island-Vietnam Area on Saturday Oct 24. *Alternate Forecast Scenario: There is a possibility that LUPIT might track more WSW-ward earlier than expected with a strike across the southern part of Northern Luzon thru Isabela Province or Southern Cagayan. This scenario is likely if the high pressure steering ridge located off Eastern China strengthens more and dig deeper southward. The probability of this alternate forecast still remains low. 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 continues to exhibit impressive convective bands in all quadrants, however, the the EYE has decreased to just 35 km from 55 km. Its outer & inner rain bands remains at sea...not affecting any major islands at this time. LUPIT may begin to affect Northern Luzon beginning late Wednesday (Oct 21) - if the forecast movement continues, thus deteriorating weather conditions can be 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!]

    *ANIMATED MULTISPECTRAL SATELLITE
    IMAGERY SHOWS THAT STY 22W HAS STARTED TO TRACK IN A WESTWARD
    DIRECTION AND HAS INCREASED TRACK SPEED OVER THE PAST 06 HOURS. THE
    EYE HAS DECREASED IN SIZE TO APPROXIMATELY 20 NM FROM 30 NM AT
    182330Z. SUBSEQUENTLY, THE CURRENT INTENSITY HAS BEEN DECREASED
    SLIGHTLY TO REFLECT THIS CHANGE. AS A MID-LATITUDE TROUGH HAS MOVED
    OUT TO THE NORTHEAST OF LUPIT, A DECREASE IN POLEWARD OUTFLOW HAS
    BEEN NOTED IN ANIMATED ENHANCED WATER VAPOR IMAGERY. RADIAL OUTFLOW
    IS EXPECTED TO REMAIN, ALLOWING LUPIT TO REMAIN A STRONG TYPHOON
    THROUGHOUT THE FORECAST PERIOD. THE LACK OF AN ENHANCED POLEWARD
    OUTFLOW CHANNEL WILL HINDER SUFFICIENT OUTFLOW FOR 22W TO REMAIN A
    SUPER TYPHOON BEYOND TAU 24. THE SUBTROPICAL RIDGE TO THE NORTH OF
    LUPIT HAS BECOME THE DOMINANT STEERING INFLUENCE AND WILL CONTINUE
    TO TRACK THE SYSTEM WESTWARD TOWARDS NORTHERN LUZON. LANDFALL WITH
    LUZON IS EXPECTED TO OCCUR AROUND TAU 72...
