Typhoon “Bising” (international name “Bising”) has slowed down again, now moving northwest east of mainland Cagayan before Wednesday noon, April 21.


In its 11 a.m. severe weather bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration’s (PAGASA) said the center of the eye of Bising was located at 360 kilometers (km) east of Tuguegarao City, Cagayan around 10 a.m.

It has maintained its maximum sustained winds of 175 kilometers per hour (kph) near the center and gustiness of up to 215 kph while moving at 10 kph.


Tropical cyclone wind Signal No. 2 has been lifted but Signal No. 1 remains hoisted over Batanes, Cagayan including Babuyan Islands, eastern portion of Apayao, eastern portion of Kalinga, eastern portion of Isabela, northeastern portion of Quirino, and northern portion of Aurora.

“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. (Likewise), destructive typhoon-force winds extend outward up to 90 km from the center of the typhoon,” PAGASA warned.

In the next 24 hours, PAGASA said 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 Northern Luzon that are not under any tropical cyclone wind signal.


Bising and the enhanced northeasterly surface wind flow may also trigger rough to high seas over the northern and eastern seaboards of Luzon with wave heights up to 2.5-9.0 meters (m).

Rough to very rough seas will likewise prevail over the western coastline of Northern Luzon (2.8-4.5 m) and the northern and eastern coasts of Northern Samar (2.5-5.0 m).

“Sea travel is risky for all types of seacrafts over these waters,” PAGASA advised.

Bising’s projected track and intensity

Typhoon Bising is expected to continue to move generally north or north-northwest until Thursday morning, April 22 when the typhoon will be nearest the landmass of northern Luzon, PAGASA said.

Afterward, the typhoon will begin to move northeast away from the Luzon landmass between Friday, April 23, and Saturday, April 24.

Bising will likely leave the Philippine area of responsibility (PAR) by Sunday, April 25.

PAGASA said Bising will gradually weaken throughout the forecast period and could be downgraded into a severe tropical storm by Saturday and a tropical storm by Sunday.

Bising will likely be at 330 km east of Calayan, Cagayan by Thursday morning; 570 km east of Itbayat, Batanes by Friday morning; 985 km east of extreme northern Luzon by Saturday morning; and 1,585 km east of extreme northern Luzon or outside the PAR by Sunday morning.
