Typhoon LUPIT (RAMIL) downgraded into a Category 1 system with winds of 150 kph...moving WSW in the direction of Extreme Northern Luzon. Outer rainbands to reach the area tonight.

*Residents and visitors along Northern Luzon & Taiwan 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 decelerate as it tracks WSW w/in the next 12 to 24 hours. Its wind speed will slightly strengthen back to Category 2 (165 kph) as it moves closer to the coast of Northeastern Luzon due to improved atmospheric conditions (warm ocean moisture & unstable air). The 2 to 5-day Long-Range Forecast shows LUPIT making landfall over the northern coast of Cagayan on Saturday morning, Oct 24 approx. 7-8AM - crossing Apayao and Ilocos Norte throughout Saturday. The core shall be off Laoag City on Sunday morning Oct 25 at around 7-8 AM. By Monday morning, Oct 26, LUPIT shall be moving slowly across the South China Sea, away from Ilocos Norte. *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, then move NW to Northward into Taiwan or SE China. This scenario is likely as some models deviates from the abovementioned forecast. The probability of this alternate forecast remains high, so a possible shift can happen. Please be reminded that the Forecast Outlook changes every 6 hours, so a turn to the left or right of its future track and other conditions must be considered. So please stay tuned.

+ Effects: LUPIT's circulation remains organized & large with a cloud-filled EYE. The outer & inner rain bands remains at sea...not yet affecting any major islands at this time, however, LUPIT may begin to affect Extreme Northern Luzon beginning tonight - if the forecast movement continues...deteriorating weather conditions can be expected within the next 48 to 72 hours. 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. 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. Possible coastal Storm Surge flooding of 4 to 5 feet above normal tide levels...accompanied by large and dangerous battering waves...is possible along the coastal areas of Extreme Northern Luzon especially along Cagayan, Batanes-Calayan-Babuyan Island Group, Isabela & Ilocos Norte. Very minimal damage is likely on this type of storm surge. Danger from Rip Currents or Rip Tides can be expected along the beach-front areas of Northern Luzon & Taiwan.

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