Typhoon Bising weakens while decelerating over the Philippine Sea east of Babuyan Islands, Pagasa reported on its Wednesday weather bulletin.
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 Tropical Cyclone Wind Signal #1).
In the next 24 hours, under the influence of Typhoon “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.
Typhoon Bising weakens while decelerating over PH Sea
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.
On the forecast track, Typhoon Bising will move generally northward or north northeastward today away from the landmass of Luzon before turning east northeastward tomorrow (23 April) and eastward on Saturday (24 April). The typhoon is forecast to exit the Philippine Area of Responsibility on Saturday evening or Sunday (25 April) early morning.
Typhoon Bising will gradually weaken throughout the remainder of the forecast period. It is forecast to be downgraded to severe tropical storm category by tomorrow and tropical storm category by Saturday before transitioning into an extratropical cyclone outside the PAR on Monday (26 April).
