Refer to Weather Advisory No. 34 issued at 11:00 PM today for the heavy rainfall outlook due to “OFEL” and “PEPITO”.
Severe Winds
The wind signals warn the public of the general wind threat over an area due to the tropical cyclone. Local winds may be slightly stronger/enhanced in coastal and upland/mountainous areas exposed to winds. Winds are less strong in areas sheltered from the prevailing wind direction.
• Significant to severe impacts from typhoon-force winds are possible within any of the areas under Wind Signal No. 4.
• Moderate to significant impacts from storm-force winds are possible within any of the areas under Wind Signal No 3.
• Minor to moderate impacts from gale-force winds are possible within any of the areas under Wind Signal No. 2.
• Minimal to minor impacts from strong winds are possible within any of the areas under Wind Signal No. 1.
Coastal Inundation
There is a high risk of life-threatening storm surge with peak heights exceeding 3.0 m in the next 48 hours over the low-lying or exposed coastal localities of Batanes, Ilocos Norte, Ilocos Sur, Cagayan including Babuyan Islands, Isabela, and northern Aurora. Refer to Storm Surge Warning No. 10 issued at 8:00 PM today for the details.
HAZARDS AFFECTING COASTAL WATERS
A Gale Warning is hoisted over the northern and eastern seaboards of Northern Luzon. Refer to Gale Warning No. 5A issued at 11:00 PM today for more details.
24-Hour Sea Condition Outlook
Up to very rough or high seas over the following coastal waters:
• Up to 8.0 m: The seaboards of Batanes and Babuyan Islands
• Up to 7.0 m: The northern seaboards of Ilocos Norte and mainland Cagayan
• Up to 5.5 m: The eastern seaboard of mainland Cagayan
• Sea travel is risky for all types or tonnage of vessels. All mariners must remain in port or, if underway, seek shelter or safe harbor as soon as possible until winds and waves subside.
Up to rough seas over the following coastal waters:
• Up to 4.0 m: The seaboards of Isabela and northern Aurora
• Mariners of small seacrafts, including all types of motorbancas, are advised not to venture out to sea under these conditions, especially if inexperienced or operating ill-equipped vessels.
Up to moderate seas over the following coastal waters:
• Up to 2.5 m: The western seaboard of Ilocos Norte; the northern and eastern seaboards of Catanduanes and Northern Samar; the eastern seaboards of Albay, Sorsogon, Eastern Samar, Dinagat Islands, Surigao del Norte including Siargao and Bucas Grande Islands, Surigao del Sur, and Davao Oriental
• Up to 2.0 m: The remaining seaboard of Aurora; the eastern seaboard of Quezon including Polillo Islands; the seaboard of Camarines Norte; the northern and eastern seaboards of Camarines Sur; the remaining seaboard of Catanduanes
• Mariners of motorbancas and similarly-sized vessels are advised to take precautionary measures while venturing out to sea and, if possible, avoid navigation under these conditions.
TRACK AND INTENSITY OUTLOOK
• OFEL will continue moving northwestward and pass close or make landfall in the vicinity of Babuyan Islands tonight before turning north northwestward to northward tomorrow (15 November) until Saturday (16 November) morning over the sea west of Batanes. This is the period when the tropical cyclone is outside the Philippine Area of Responsibility (PAR). OFEL will then turn northeastward towards Taiwan while re-entering the PAR over the rest of the weekend. Note that hazards on land and coastal waters may still be experienced in areas outside the landfall point and the forecast confidence cone. Furthermore, the track may still shift within the limit of the forecast confidence cone.
• OFEL is forecast to continue to weaken throughout the forecast period due to frictional effects of land as well as the increasingly unfavorable environment over the Luzon Strait and the sea east of Taiwan, where OFEL may weaken into a remnant Low.
Considering these developments, the public and disaster risk reduction and management offices concerned are advised to take all necessary measures to protect life and property. Persons living in areas identified to be highly or very highly susceptible to these hazards are advised to follow evacuation and other instructions from local officials. For heavy rainfall warnings, thunderstorm/rainfall advisories, and other severe weather information specific to your area, please monitor products issued by your local PAGASA Regional Services Division.
The next tropical cyclone bulletin will be issued at 2:00 AM tomorrow.
