Typhoon MIRINAE (SANTI) continues to threaten a wide-swath of areas in Luzon with landfall projection either Aurora or Northern Quezon...now tracking Westward during the past 3 hours.

*Residents and visitors along the eastern coast of Luzon (from Cagayan down to Bicol Peninsula) should closely monitor the progress of MIRINAE (SANTI).

*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: MIRINAE's forecast outlook continues to change more to south matching the ECMWF (European) guidance model...expected to cross the heart of Central Luzon. The 2 to 5-day Medium-Range Forecast now shows the system approaching the northern coast of Bicol Region tomorrow night - passing more or less 150 km. North of Naga City around 10 PM. The core (eye and eyewall) will pass over Polillo Island around 2 AM Saturday and make landfall over Northern Quezon just north of Infanta between 5-6 AM as a Category 2 typhoon w/ winds of 160 kph. It will then cross Bulacan, Pampanga around 10 AM - passing about 25 km. North of Quezon City and will be over Subic Bay/Olongapo City area at around 2 PM Saturday. MIRINAE will be in the middle of the South China Sea on Sunday, November 01 and will be downgraded into a Tropical Storm before making its final landfall over Vietnam on Monday, Nov 02. It will dissipate over Cambodia on Nov 03. 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 possibilities must be considered.

+ Effects: MIRINAE's convective circulation has slightly weakened but its wind speed remained intact. The EYE remains cloud-filled w/ its rainbands still at sea and not yet affecting parts of Eastern Luzon. The initial effects of the outer rainbands of MIRINAE over Eastern Luzon including Bicol Region can be expected beginning tomorrow morning. 6-hr total rainfall amounts of 02 up to 100 mm (moderate to heavy rain) can be expected along its rainbands...with isolated amounts of 250 mm (heavy to very heavy rain) near the center of Mirinae. Click here to view the latest NOAA's eTRaP graphic on the storm's rainfall amount. People living around the slopes of Mayon Volcano in Albay & of Bulusan Volcano in Sorsogon - especially along the areas where possible MUDFLOWS (LAHAR) FLOWS (mixture of volcanic mud and water) are located must stay alert as moderate to heavy rains associated by this system are likely to affect the area beginning tomorrow. 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 6 to 8 feet above normal tide levels...accompanied by large and dangerous battering waves...is possible along the coastal areas of Bicol Region and Eastern Luzon. Moderate 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 Eastern & Northern Visayas.

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