HAZARDS AFFECTING LAND AREAS

Heavy Rainfall

Typhoon INDAY remains less likely to directly bring heavy rains in the country throughout the forecast period. However, its outermost rainbands and the Southwest Monsoon may bring rainshowers and thunderstorms over Batanes and the western sections of Central and Southern Luzon.  For more information, refer to the 24-Hour Public Weather Forecast issued at 4:00 AM today.

Severe Winds

• The latest forecast scenario for INDAY shows that while the hoisting of Tropical Cyclone Wind Signals remains less likely at this time, further westward shift in the track forecast and/or expansion in the extent of tropical cyclone winds may result in the hoisting of wind signals over portions of Extreme Northern Luzon. 

• Gusty conditions reaching strong to gale-force strength may be experienced over Extreme Northern Luzon tomorrow due to the channeling of the typhoon circulation in the Luzon Strait.

HAZARDS AFFECTING COASTAL WATERS

• Under the influence of Typhoon INDAY, a Gale Warning remains effect for the northern seaboards of Northern Luzon. For more information, refer to Gale Warning #2 issued at 5:00 AM today.

• In the next 24 hours, INDAY may also bring moderate to rough seas over the eastern seaboard of Northern Luzon (1.2 to 3.0 m). These conditions may be risky for those using small seacrafts. Mariners are advised to take precautionary measures when venturing out to sea and, if possible, avoid navigating these conditions.

TRACK AND INTENSITY OUTLOOK

• INDAY is forecast to move generally north northwestward over the Philippine Sea east of Taiwan today through tomorrow morning, gradually decelerating during the process. For the rest of Monday through Tuesday, the typhoon will move northward slowly towards the vicinity of Yaeyama Islands and the East China Sea. On the track forecast, INDAY may exit the Philippine Area of Responsibility on Tuesday morning or afternoon.

• Further intensification will continue today through tomorrow morning as INDAY tracks northwestward over the sea east of Taiwan. However, the slightly cooler waters east of Taiwan and the forecast slow-down period over this sea area may result in a weakening trend beginning late tomorrow or on 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. 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 PM today.
