HAZARDS AFFECTING LAND AREAS

Heavy Rainfall

• This late afternoon through evening: Light to moderate with at times heavy rains possible over Batanes.

• Tomorrow: Moderate to heavy rains likely over Batanes and Babuyan Islands.

• Saturday early morning through afternoon: Moderate to heavy rains possible over Batanes. Light to moderate with at times heavy rains possible over Babuyan Islands.

• Under these conditions, isolated to scattered flooding (including flash floods) and rain-induced landslides are possible especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps, and in localities with significant antecedent rainfall.

• This tropical cyclone is also forecast to enhance the Southwest Monsoon which may bring rains over the western section of Luzon beginning tomorrow. As such, the issuance of Weather Advisory for Southwest Monsoon is likely.

Severe Winds

Due to the forecast expansion in the extent of tropical cyclone winds associated with Super Typhoon HENRY, Tropical Cyclone Wind Signals (TCWS) may be hoisted for localities in Extreme Northern Luzon by today at the earliest in anticipation of potential strong breeze to near gale conditions. The potential for hoisting a Wind Signal No. 2 is also not ruled out.

HAZARDS AFFECTING COASTAL WATERS

• Under the influence of Super Typhoon HENRY, a Gale Warning is in effect for the northern and eastern seaboards of Northern Luzon. For more information, refer to Gale Warning #1 issued at 5:00 AM today.

• In the next 24 hours, HENRY may bring moderate to rough seas over the eastern seaboard of Isabela (1.2 to 4.0 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 in these conditions.

TRACK AND INTENSITY OUTLOOK

• Super Typhoon HENRY is forecast to continue moving generally south southwestward today through tomorrow early morning while decelerating. By tonight or tomorrow early morning, the tropical cyclone may become almost stationary. By tomorrow afternoon, HENRY may begin tracking slowly northwestward before eventually accelerating northward by Saturday. On the forecast track, HENRY may exit the Philippine Area of Responsibility on Saturday evening or Sunday morning.

• This super typhoon is forecast to further intensify during the remaining time window before it enters its slowdown or quasi-stationary phase, when it is likely to begin weakening. Once it begins accelerating northward during the weekend, a slight re-intensification may still occur.

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.
