• Minor to moderate impacts from strong winds are possible within any of the localities where Wind Signal No. 2 is hoisted.
• Minimal to minor impacts from strong winds are possible within any of the areas under Wind Signal No. 1.
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):

For more information, refer to Storm Surge Warning No. 4 issued at 2:00 AM today. Refer to official hazard maps for specific areas susceptible to storm surge inundation in these provinces.
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 the seaboards of Northern Luzon and the eastern seaboard of Central Luzon. Sea travel is risky for small seacrafts, including all types of motorbancas. For more information, refer to Gale Warning No. 5 issued at 5:00 AM today.
• Rough seas over the western seaboard of Northern Luzon outside Gale Warning areas (2.5 to 4.0 m). Moderate to rough seas over the western seaboard of Central Luzon (1.5 to 3.0 m), the seaboards of Southern Luzon (2.0 to 3.5 m), and the western seaboard of Visayas (1.5 to 2.5 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.
• Slight to moderate seas are expected over the eastern seaboards of Visayas and Mindanao (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
• On the track forecast, ENTENG will exit the Philippine Area of Responsibility tomorrow morning. Outside the PAR region, the tropical storm will move generally westward until Friday morning, then turn west northwestward for the remainder of the forecast period. ENTENG may make another landfall in the vicinity of southern mainland China during the weekend.
• ENTENG is forecast to intensify throughout the forecast period and may reach severe tropical storm category in the next 12 hours, and typhoon category on Thursday. The tropical cyclone may reach its peak intensity by late Friday or early Saturday prior to making landfall in mainland China.
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.
