Under these conditions, flooding and rain-induced landslides are expected especially in areas that are highly or very highly susceptible to these hazards as identified in official hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.

Furthermore, the enhanced Southwest Monsoon will bring moderate to intense rainfall in other areas of Luzon and Visayas (especially along the western portions). For more information, refer to Weather Advisory No. 4 issued at 11:00 PM today.

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

• From tomorrow evening to Tuesday evening: Zambales, Bataan, Aurora, Bulacan, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Visayas, and Caraga Region.

• From Tuesday evening to Wednesday evening: Zambales, Bataan, Aurora, Bulacan, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, and Western Visayas.

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, Caraga Region, the seaboard of Northern Mindanao, and 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 until tomorrow (2 September). ENTENG is forecast to be over the coastal waters of Isabela by tomorrow evening. So far, no landfall has been recorded.

• From tomorrow evening to Tuesday morning (3 September), ENTENG will move generally north northwestward before turning west northwestward over the Luzon Strait from Tuesday morning onwards, 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 a 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 maintain tropical storm category until Tuesday and will intensify into a severe tropical storm by Wednesday. It may also reach a peak category of typhoon by Thursday or Friday. Changes in the intensity forecast is still likely over the Philippine Sea due to favorable conditions.

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.
