Furthermore, the enhanced Southwest Monsoon will bring moderate to intense rainfall in other areas of Luzon (especially along the western portions) over the next three days. For more information, refer to Weather Advisory No. 6 issued at 11:00 PM yesterday.
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.
• 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):
• Today (3 September): Ilocos Region, Nueva Vizcaya, Quirino, Zambales, Bataan, Aurora, Bulacan, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Western Visayas, Negros Island Region, and Northern Samar.
• Tomorrow (4 September): Ilocos Region, Abra, Benguet, Zambales, Bataan, Bulacan, Aurora, Metro Manila, CALABARZON, MIMAROPA, Bicol Region, Western Visayas, Negros Occidental, and Northern Samar.
Coastal Inundation
A minimal to moderate risk of storm surge may occur in the next 48 hours in the low-lying or exposed coastal localities of Batanes, Cagayan, Isabela, Ilocos Norte, Ilocos Sur, and northern Aurora. For more information, refer to Storm Surge Warning No. 3 issued at 8:00 PM yesterday. 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 seaboards of Central and Southern Luzon. Sea travel is risky for small seacrafts, including all types of motorbancas. For more information, refer to Gale Warning No. 4 (intermediate) issued at 11:00 PM yesterday.
• Moderate to rough seas over the western seaboard of Northern and Central Luzon (1.5 to 3.0 m), the western seaboard of Southern Luzon, the eastern and southern seaboards of Southern Luzon outside Gale Warning areas, 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
• ENTENG is forecast to continue moving northwestward and emerge over the northwestern portion of Ilocos Region by this morning. From this afternoon until Thursday (5 September), ENTENG will move generally westward over the West Philippine Sea. On the track forecast, this tropical cyclone may exit the Philippine Area of Responsibility by tomorrow (4 September) morning.
• ENTENG is forecast to maintain tropical storm category during its traverse of mainland Northern Luzon. Further intensification is forecast to occur from this afternoon onwards, with ENTENG becoming a severe tropical storm by this afternoon (at the earliest) or evening, and typhoon category by Thursday.
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.
