TYPHOON LUPIT [RAMIL/22W/0920]
T2K PUBLIC ADVISORY NUMBER 018

View: Advisory Archives (2004-2009)

  • Typhoon LUPIT (RAMIL) weakens over the Northern Philippine Sea as it enters an area of drier and stable air...downgraded to Category 3.

    *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 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. This ridge will steer LUPIT into Extreme Northern Luzon...making landfall over Eastern Cagayan on Thursday evening Oct 22...passing very close to the south of Aparri. The core (eye & eyewall) of LUPIT shall cross Abra, Kalinga and exit over Ilocos Sur whole day Friday Oct 23 and shall be over the South China Sea by early Saturday morning, Oct 24. It shall move westward to WNW 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 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 has deteriorated upon entering an area of drier air. The eye has become cloud-filled 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 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!]

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

    2 PM (06 GMT) 20 OCTOBER: 20.1N 129.6E / 175-215 KPH (TY-Cat 2) / W @ 17 KPH
  • 2 AM (18 GMT) 21 OCTOBER: 19.9N 127.7E / 185-230 KPH (TY-Cat 3) / WSW @ 17 KPH

    REMARKS: 2 AM (18 GMT) TUE 20 OCTOBER POSITION: 19.8N 131.5E.
    *THE CURRENT POSITION AND INTENSITY
    ESTIMATES ARE CONSISTENT WITH RECENT DVORAK SATELLITE FIXES FROM
    PGTW AND RJTD. TY 22W IS TRACKING EAST-NORTHEASTWARD UNDER THE
    STEERING INFLUENCE OF A SUBTROPICAL RIDGE EXTENSION TO THE NORTHEAST
    OF THE CYCLONE. THE TYPHOON WILL CONTINUE TO TRACK GENERALLY
    WESTWARD IN THE CURRENT STEERING FLOW PATTERN FOR THE NEXT 24 HOURS.
    THEREAFTER, THE FLOW ASSOCIATED WITH A SECOND SUBTROPICAL RIDGE TO
    THE NORTHWEST WILL EXERT A SLIGHT EQUATORWARD PUSH. DURING THE NEXT
    12 HOURS, TY 22W WILL WEAKEN SLIGHTLY AS IT MOVES THROUGH A NARROW
    SLOT OF DRIER AND MORE STABLE AIR NOTED IN RECENT MICROWAVE
    SATELLITE IMAGERY AND TOTAL PRECIPITABLE WATER PRODUCTS. AFTER TAU
    12, HIGH ALONG TRACK OCEAN HEAT CONTENT, LOW VERTICAL WIND SHEAR,
    AND GOOD UPPER LEVEL OUTFLOW WILL ALLOW THE SYSTEM TO MAINTAIN
    INTENSITY OR PERHAPS INTENSIFY SLIGHTLY PRIOR TO MAKING LANDFALL IN
    LUZON BETWEEN TAU 48 AND TAU 72. LAND INTERACTION AND DECREASING
    POLEWARD OUTFLOW WILL WEAKEN TY 22W BETWEEN TAU 48 AND TAU 96. AS
    THE STORM ENTERS THE SOUTH CHINA SEA, UPPER LEVEL SUPPORT SHOULD
    IMPROVE ONCE AGAIN, HALTING THIS WEAKENING TREND...
