    'Bagyong Jolina' PAGASA signal


    Recent landfalls: Almagro, Samar (6:30 AM)

    Within the next 12 hours, the typhoon is forecast to make landfall in the vicinity of Masbate (mainland or Ticao Island).

    Beyond the next 12 hours, 'Jolina' will move northwestward towards Burias Island and the vicinity of Ragay Gulf before making another landfall in the vicinity of southeastern Quezon tonight or tomorrow early morning. Prolonged interaction with land may result in its weakening into a severe tropical storm.

    By tomorrow afternoon, the typhoon will briefly emerge over Lopez Bay before making landfall in the vicinity of northern Quezon. Throughout the remainder of tomorrow and into Thursday morning, the tropical cyclone is forecast to cross Central Luzon (roughly to the east and north of Metro Manila).

    'Bagyong Jolina' PAGASA track

    Frictional effects during its traverse of Luzon landmass will weaken the cyclone down to tropical storm category.

    'JOLINA' is forecast to emerge over the West Philippine Sea before noon on Thursday. Re-intensification is forecast to occur beginning on Thursday afternoon as the tropical cyclone moves west northwestward over the West Philippine Sea towards the southern China-northern Vietnam area.

    'Bagyong Jolina' PAGASA intensity


    Heavy Rainfall

    In the next 24 hours, 'Jolina' may bring heavy to intense with at times torrential rains over Northern Samar, Eastern Samar, Samar, Leyte, Biliran, Sorsogon, Albay, Romblon, and Masbate. Moderate to heavy with at times intense rains are also likely over the southern portion of Quezon, Occidental Mindoro, Oriental Mindoro, Marinduque, and the rest of Bicol Region and Visayas.

    Under these conditions, scattered to widespread 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.

    Severe Winds

    Destructive typhoon-force winds are likely to occur within any of the areas where Signal No. 3 is in effect. This may bring generally moderate to heavy damage to structures and vegetation.

    Damaging gale-force to storm-force winds are likely to occur within any of the areas where Signal No.2 is in effect. This may bring generally light to moderate damage to structures and vegetation.

    Strong winds (strong breeze to near gale conditions) with occasional gusts will be experienced in areas where Signal No. 1 is in effect. This may result to up to very light damage to structures and vegetation.

    Coastal Inundation

    In the next 24 hours, the threat of coastal inundation due to storm surge of up to 0.5-1.0 m continues for several coastal localities of Biliran, Sorsogon, Samar, and Masbate which may pose threat to life and property. In addition, coastal areas of localities under TCWS, especially those at No. 2 and No. 3 may experience coastal flooding due to hazardous surf conditions.


    In the next 24 hours, Typhoon 'Jolina' will bring rough to very rough seas (2.5 to 5.0 m) over the seaboards of areas where Signal No. 2 and 3 are in effect.

    Sea travel is risky for all types of seacrafts over these waters. Mariners without the proper experience should immediately seek safe harbor.

    Moderate to rough seas (1.2 to 2.8 m) will be experienced over the seaboards of areas where Signal No. 1 is in effect, the remaining seaboards of Visayas, and the northern eastern seaboards of Mindanao.

    Mariners of small seacrafts are advised to take precautionary measures when venturing out to sea. Inexperienced mariners should avoid navigating in these conditions.


    'Jolina', the 10th tropical cyclone for 2021, developed into Tropical Depression on Monday, September 6.

    PAGASA predicts that 2–3 tropical cyclones may enter/develop in the PAR this month.

    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.
