Heavy Rainfall Outlook
Refer to Weather Advisory No. 13 issued at 11:00 AM today for the heavy rainfall outlook due to Tropical Cyclone ADA.
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 gale-force winds are possible within any of the areas under Wind Signal No. 2.
• Minimal to minor impacts from strong winds are possible within any of the areas under Wind Signal No. 1.
Since further intensification to severe tropical storm is not ruled out, raising of Wind Signal No. 3 is possible.
The Northeast Monsoon and the periphery of ADA will also bring strong to gale-force gusts over the following areas (especially in coastal and upland areas exposed to winds):
• Today: Batanes, Babuyan Islands, Ilocos Norte, northern and eastern mainland Cagayan, Isabela, Quirino, Aurora, Quezon, Romblon, Oriental Mindoro, Aklan, Capiz, northern Cebu, Eastern Visayas, and Dinagat Islands
• Tomorrow (18 January): Batanes, Cagayan, Isabela, Quirino, Ilocos Norte, Abra, Aurora, Quezon, Marinduque, Romblon, Bicol Region, and Northern Samar

Refer to Storm Surge Warning No. 7 issued at 8:00 AM today for more details.

Up to rough seas over the following coastal waters:
• Up to 4.0 m: The seaboard of Babuyan Islands; the eastern seaboard of mainland Cagayan.

• Up to 3.0 m: The seaboards of Ilocos Norte and Ilocos Sur; the remaining seaboard of mainland Cagayan.
• 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.

TRACK AND INTENSITY OUTLOOK
• It must be emphasized that heavy rainfall and severe winds may still be experienced in localities outside the landfall point and the forecast confidence cone. Refer to “Other Hazards affecting Land Areas” for more details. Furthermore, the track may still shift within the limit of the forecast confidence cone.
• ADA will move generally northwestward today before slowly turning northward to northeastward tomorrow (18 January). From tomorrow onwards, ADA is forecast to move slowly in a looping pattern over the sea east of Southern Luzon.
• A further westward shift in the forecast track may result in a possible landfall over Catanduanes. Furthermore, changes in forecast track over the succeeding bulletins is possible.
• ADA is forecast to remain as a tropical storm while moving over the sea east of Southern Luzon. However, further intensification to severe tropical storm is not ruled out. This tropical cyclone will then weaken into a tropical depression by Tuesday (20 January) afternoon or evening due to the effects of the surge of the northeast monsoon.
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 PM today.
