    TRACK AND INTENSITY OUTLOOK


    Tropical Storm 'Maring' will continue to move west northwestward until this morning or afternoon before turning westward.

    On the track forecast, the storm will be moving over the Luzon Strait between this afternoon and tomorrow early morning and pass very close or over the Babuyan Islands, without ruling out the possibility of landfall over mainland northern Cagayan or a close approach over Batanes.

    However, considering the short-period acceleration observed over the past couple of hours, a slightly earlier traverse of Extreme Northern Luzon (i.e., beginning this morning) remains a possibility.

    'Maring' is forecast to exit the Philippine Area of Responsibility tomorrow morning or afternoon.

    Outside the PAR, the storm will continue moving westward over the West Philippine Sea until it makes landfall in the vicinity of Hainan Island on Wednesday morning or afternoon.

    'Maring' is forecast to consolidate in the near term and intensify into a severe tropical storm within the next 12 hours.

    Furthermore, this tropical cyclone may reach typhoon category tomorrow over the West Philippine Sea. Weakening will likely take place on Wednesday once 'Maring' makes landfall in Hainan Island.

    HAZARDS AFFECTING LAND AREAS

    Heavy Rainfall

    Today, moderate to heavy with at times intense rains are highly likely over Batanes, Cagayan including Babuyan Islands, Cordillera Administrative Region, and Ilocos Region.

    Light to moderate with at times heavy rains are also possible over Central Luzon and the rest of Cagayan Valley.

    Under these conditions, scattered 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, Zamboanga Peninsula, Palawan and Occidental Mindoro in the next 24 hours.

    Severe Winds

    Considering the likelihood of reaching severe tropical storm category prior or during its passage of the Luzon Strait, winds may reach gale- 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 be experienced 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.

    Due to the expansive wind field of the tropical storm and the enhanced Southwest Monsoon, occasional gusts reaching strong to gale-force in strength are possible over the island, coastal, and upland/mountain localities of Visayas, Dinagat Islands, Surigao del Norte, Agusan del Norte, Misamis Oriental, Misamis Occidental, Camiguin, Zamboanga del Norte, and the rest of Luzon.

    HAZARDS AFFECTING COASTAL WATERS

    Under the influence of Tropical Storm 'Maring', a Gale Warning is in effect for the eastern seaboards of Southern Luzon and Visayas.

    In the next 24 hours, rough to high seas (2.5 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.

    Within the same period, moderate to rough seas (1.2 to 2.8 m) will prevail the remaining seaboards of Luzon and Visayas, and the northern, eastern, and western seaboards of Mindanao. 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.

    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.
