Beginning Tuesday (20 January) evening, ADA is forecast to move southeastward while moving over the sea east of Bicol Region. On the forecast track, the center of ADA may pass close to Eastern Samar and Northern Samar tomorrow and Catanduanes by Sunday. A further westward shift in the forecast track may result in a possible landfall over Eastern Visayas and Bicol Region. The track forecast may change in succeeding bulletins, especially for tomorrow or Sunday period.
• ADA is forecast to remain a tropical storm category while moving over the sea east of Visayas and Southern Luzon. This tropical cyclone may weaken into a tropical depression by Tuesday.
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.
