LUPIT (RAMIL) has rapidly intensified...now classified as a Super Typhoon, with 1-min. avg winds of 240 km/hr...still heading ENE across the Philippine Sea.

*Residents and visitors along 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 slow down further for the next 24 hours, as the influence of the mid-level low pressure trough off Japan on this system dissipates. The 2 to 5-day Long-Range Forecast shows LUPIT returning back to its Westward path, as the High Pressure Steering Ridge building off China strengthens and moves across east of Taiwan. This ridge will steer LUPIT into Extreme Northern Luzon & South China Sea from Tuesday until Friday (Oct 19-23), reaching the Category 5 treshold strength (250 kph). LUPIT shall pass very close to the coastal beach front areas of Northern Cagayan and Ilocos Norte, with a close approach of about 5 to 15 km. to the north of Pagudpod, Ilocos Norte on Thursday afternoon, Oct 22nd. *Alternate Forecast Scenario: There is a possibility that LUPIT might do a clockwise loop and track more WSW-ward than forecasted with a strike across Northern or Central Luzon. This scenario is likely if the high pressure steering ridge located off Eastern China strengthens more. This alternate forecast remains low at this time. 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 more impressive, w/ a 40-km. slightly irregular Eye. Its outer & inner rain bands remains at sea...not affecting any major islands at this time. LUPIT may begin to affect Northern Luzon - if the forecast track becomes a reality, thus deteriorating weathern conditions can be expected beginning Tuesday (Oct 20). 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!]
