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.
• Minimal to minor impacts from strong winds are possible within any of the areas under Wind Signal No. 1.
The highest possible Wind Signal that may be hoisted during the passage of ENTENG is Wind Signal No. 2 or 3.
The enhanced Southwest Monsoon will also bring strong to gale-force gusts over the following areas (especially in coastal and upland areas exposed to winds):
• From tonight to tomorrow evening: MIMAROPA, Western Visayas, Central Visayas, Negros Island Region, Eastern Visayas (outside Wind Signal areas), Caraga Region, Northern Mindanao, and Zamboanga Peninsula

HAZARDS AFFECTING COASTAL WATERS
In the next 24 hours, ENTENG and the enhanced Southwest Monsoon will bring the following conditions over the coastal waters of the country:
• Gale Warning is in effect over Catanduanes, Camarines Norte, the eastern coast of Camarines Sur, the eastern coast of Albay, the eastern coast of Sorsogon, and the northern and eastern coast of Northern Samar. Sea travel is risky for small seacrafts, including all types of motorbancas. For more information, refer to Gale Warning No. 1 issued at 5:00 PM today.
• Moderate to rough seas over the eastern seaboards of Central Luzon and Southern Luzon outside Gale Warning areas (1.5 to 3.5 m), the eastern seaboard of Eastern Samar, and the seaboard of Kalayaan Islands (1.5 to 3.0 m). 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.
• Moderate seas are expected over the southern seaboard of CALABARZON, the remaining seaboards of Bicol Region, Palawan, and Eastern Visayas, the seaboard of Western Visayas, the northern and eastern seaboard of Caraga Region, and the eastern seaboard of Davao Oriental (1.5 to 2.5 m). Slight to moderate seas are possible for the eastern seaboard of mainland Northern Luzon, the remaining seaboards of MIMAROPA, Visayas, and Caraga Region, the seaboard of Northern Mindanao, the eastern seaboard of Davao Occidental (1.0 to 2.0 m). 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
• ENTENG is forecast to move generally northwestward to west northwestward until tomorrow (2 September) early morning and make landfall in the vicinity of Catanduanes within the next 3 hours and mainland Bicol Region within the next 12 hours. For the remainder of tomorrow, ENTENG will turn more north northwestward or northward after emerging over the waters north of Camarines Provinces and move over the waters east of Luzon.
• From Tuesday (3 September) onwards, ENTENG will move generally west northwestward over the Luzon Strait, with a period of deceleration from Tuesday to Wednesday (4 September). Another landfall in the vicinity of mainland Northern Luzon or Babuyan Islands is not ruled out. A more northwestward movement is expected by Thursday (5 September) onwards.
• There may be further westward shift in the track forecast due to the developing ridge of high pressure north of ENTENG, which may increase rainfall amounts over mainland Luzon.
• ENTENG is forecast to reach tropical storm category within the next 12 hours. It is forecast to remain at this category until early Wednesday. It may also reach a peak category of typhoon by Thursday or Friday.
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 11:00 PM today.
