    Hazards affecting land areas


    Severe Winds

    Tropical cyclone winds of at least strong breeze to near gale in strength extend outward up to 370 km from the center of the typhoon. Destructive typhoon-force winds extend outward up to 90 km from the center of the typhoon.

    In the next 24 hours, the northeasterly wind flow enhanced by the typhoon will also bring strong breeze to near gale conditions with higher gusts over the coastal and mountainous areas of Ilocos Region, Apayao, Abra, and the western portion of Cagayan (i.e., those not under Signal No. 1).

    Hazards affecting coastal waters

    In the next 24 hours, under the influence of 'Bagyong Bising' and an enhanced northeasterly wind flow, the following sea conditions will be experienced over the coastal waters of the country:

    Rough to high seas will be experienced over the northern and eastern seaboards of Northern Luzon (2.5 to 8.0 m). Sea travel is risky for all types of seacrafts over these waters.

    Rough to very rough seas over the seaboard of Aurora, the seaboards of extreme northern Quezon including the northern and eastern seaboards of Polillo Islands, and the northern seaboards of Bicol Region (2.5 to 4.5 m). Sea travel is risky for small seacrafts over these waters. Mariners without the proper experience should immediately seek safe harbor.

    Moderate to rough seas over the eastern seaboard of Bicol Region, northern and eastern seaboard of Northern Samar and the western seaboard of Northern and Central Luzon (1.5 to 3.0 m). Mariners of small seacrafts are advised not to venture out over these waters. Inexperienced mariners of these vessels should avoid navigating in these conditions.

    About the typhoon

    'Bising' entered PAR on Friday morning, April 17.

    PAGASA predicts that 1–4 tropical cyclones are expected to form between April and June.

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