Under these conditions, flooding and rain-induced landslides are possible especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps and in localities that experienced considerable amounts of rainfall for the past several days.

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.
• Minimal to minor impacts from strong winds are possible within any of the areas under Wind Signal No. 1.
Other areas in CALABARZON, MIMAROPA, Central Luzon, and Cagayan Valley may be placed under Wind Signal No.1 in the next bulletin. The highest possible Wind Signal that may be hoisted during the passage of AGHON is Wind Signal No. 2.

HAZARDS AFFECTING COASTAL WATERS

Today: AGHON will bring moderate to rough seas (1.5 to 3.5 m) over the coastal waters along the seaboards of Bicol Region, Quezon, the eastern seaboard of Eastern Visayas, and the western seaboard of Samar and Northern Samar. Mariners of motor bancas and similarly-sized vessels are advised to take precautionary measures while venturing out to sea and, if possible, avoid navigating in these conditions, especially if inexperienced or operating ill-equipped vessels.

TRACK AND INTENSITY OUTLOOK

• AGHON is forecast to move generally west northwestward to northwestward over Sibuyan Sea and Tayabas Bay, and may possibly make landfall over Marinduque within the next 12 hours. During this period, weakening into Low Pressure Area (LPA) is not ruled out. AGHON will then continue to move northward and may possibly make another landfall over Batangas or Quezon and traverse CALABARZON area. Re-intensification is possible and it may reach tropical storm category by tomorrow.
• Around tomorrow afternoon or evening, AGHON will begin to recurve towards the northeast. As it moves over the Philippine Sea, the tropical cyclone is forecast to continuously intensify and may reach typhoon category on Wednesday. On the track forecast, AGHON may exit the PAR region no earlier than 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.
