    TRACK AND INTENSITY OUTLOOK


    After passing close or over the islands in the Babuyan Archipelago, Severe Tropical Storm 'Maring' will continue to move westward over the Luzon Strait and the West Philippine Sea throughout the forecast period.

    It is forecast to exit the Philippine Area of Responsibility (PAR) this morning or afternoon.

    Outside the PAR, 'Maring' will maintain a westward heading and is likely to make landfall in the vicinity of Hainan, China tomorrow evening.

    Within the next 36 hours, the storm is forecast to gradually intensify but is becoming less likely to reach typhoon category prior to making landfall over Hainan Island.

    HAZARDS AFFECTING LAND AREAS

    Heavy Rainfall

    Today, heavy to torrential rains are highly likely over Batanes, the northern portion of Cagayan including Babuyan Islands, Cordillera Administrative Region, and Ilocos Region.

    Moderate to heavy with at times intense rains are highly likely over Zambales, Bataan, Tarlac, and the rest of Cagayan. Light to moderate with at times heavy rains are likely over Metro Manila, Central Luzon, over the rest of Cagayan Valley.

    Under these conditions, scattered to widespread flooding (including flash floods) and rain-induced landslides are highly likely especially in areas that are highly or very highly susceptible to these hazard as identified in hazard maps.

    Under the influence of the Southwest Monsoon enhanced by Tropical Storm 'Maring', monsoon rains are possible over Western Visayas, Palawan, and Occidental Mindoro in the next 24 hours.

    Severe Winds

    Winds will continue to reach gale-force to storm-force strength within any of the areas where TCWS No. 2 is in effect. This may result in generally light to moderate damage to structures and vegetation.

    Strong winds (strong breeze to near gale conditions) with higher gusts will continue within any of the areas where TCWS No. 1 is currently in effect. This may generally bring up to very light damage to structures and vegetation.

    The expansive wind field of the severe tropical storm and the enhanced Southwest Monsoon will bring gusty conditions reaching strong to gale-force in strength over Visayas, Dinagat Islands, Surigao del Norte, Agusan del Norte, Misamis Oriental, Misamis Occidental, Camiguin, Zamboanga del Norte, and the rest of Luzon in the next 24 hours.

    Coastal Inundation

    A minimal to moderate risk of life-threatening storm surge reaching up to 1.0 m in height may occur in the next 24 hours. Rising sea water along with the high waves from the shoreline moving inland may cause flooding in the low-lying coastal localities of Batanes, northern Cagayan including Babuyan Islands, and Ilocos Norte.

    HAZARDS AFFECTING COASTAL WATERS

    In the next 24 hours, rough to high seas (2.8 to 7.5 m) will be experienced over the seaboards of areas where TCWS No. 2 and No. 1 are in effect. These conditions are risky for all types of sea vessels. Mariners are advised to remain in port or take shelter in port until winds and waves subside.

    Moderate to rough seas (1.2 to 2.5 m) will prevail the remaining seaboards of the country. These conditions are 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.

    Under the influence of Severe Tropical Storm 'Maring' and the enhanced Southwest Monsoon, Gale Warning remains in effect for the western seaboard of Central Luzon (not under any TCWS), the seaboards of Southern Luzon and Visayas, and the western, eastern, and northern seaboards of Mindanao.

    TROPICAL CYCLONES

    'Maring', the 13th tropical cyclone this year, developed into a tropical depression while east of Bicol region on Thursday afternoon, October 7. This cyclone merged with the remnant low pressure area of 'Nando' on Sunday.

    PAGASA predicts that 2–3 tropical cyclones may enter/develop in the Philippine Area of Responsibility (PAR) this month. On October 4, tropical depression 'Lannie' developed while east of Surigao del Norte and made 10 landfalls across northern Mindanao, the Visayas, and Palawan.

    On average, there are 20 tropical cyclones that could form or enter the PAR each year. Only half of those are projected to make landfall.

    The weather agency declared the onset of the rainy season on Friday, June 5.
