• 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 localities where Wind Signal No. 4 is hoisted.
• Moderate to significant impacts from storm-force winds are possible within any of the localities where Wind Signal No. 3 is hoisted.
• Minor to moderate impacts from gale-force 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 bring strong to gale-force gusts over the following areas (especially in coastal and upland areas exposed to winds):
• Today: Central Luzon (areas not under Wind Signal), Metro Manila, CALABARZON, Bicol Region, MIMAROPA, Visayas, Zamboanga del Norte, Misamis Occidental, Lanao del Norte, Camiguin, Dinagat Islands, and Davao Oriental.

Refer to Storm Surge Warning No. 6 issued at 2:00 AM today for the details.
HAZARDS AFFECTING COASTAL WATERS
A Gale Warning is in effect over the seaboards of Northern Luzon and the western seaboards of Central and Southern Luzon. Refer to Gale Warning No. 4 issued at 5:00 PM yesterday.

• Up to 6.0 m: The western seaboard of Bataan.
• Up to 4.5 m: The western seaboards of Batangas, Lubang Islands, and Occidental Mindoro; the eastern seaboards of mainland Cagayan and Isabela

Up to rough seas over the following coastal waters:
• Up to 3.5 m: The western seaboards of Palawan including Calamian Islands; the northeastern seaboard of Aurora; the eastern seaboards of Babuyan Islands
• Up to 3.0 m: The seaboards of Batanes, Marinduque, and Kalayaan Islands; the remaining seaboards of Babuyan Islands and Bataan; the southern seaboard of Quezon; the eastern seaboard of Oriental Mindoro; the northern and western seaboards of Romblon and Ilocos Norte;

TRACK AND INTENSITY OUTLOOK
• On the forecast track, the center of EMONG will make another landfall in La Union or Ilocos Sur this morning. Afterwards, it will cross the mountainous terrain of Northern Luzon and emerge over the Babuyan Channel before noon. EMONG will then move northeastward and pass close or over Babuyan Islands between this noon and afternoon. It may also pass near Batanes between this afternoon or evening.
• EMONG may maintain its strength as it makes its second landfall. A slight weakening prior to its second landfall due to increasing interaction with the terrain of northwestern Luzon is not ruled out. Nevertheless, the passage of EMONG will trigger a weakening trend, which is expected to continue for the rest of the forecast period.
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 5:00 AM today.
