Typhoon “Bising” is forecast to further move away from the country before exiting the Philippine area of responsibility (PAR) by weekend, The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.
In its 11 a.m. severe weather bulletin on Thursday, April 22, the state weather bureau said Bising maintained its strength while moving north-northeastward over east of Batanes.
State meteorologists said the eye of the typhoon was spotted 375 kilometers (km) East Northeast of Calayan, Cagayan or 320 km East of Basco, Batanes as of 10 a.m.
It had a maximum sustained winds of 150 kilometers per hour (kph) near the center and a gustiness of up to 185 kph, while moving north northeastward at 10 kph.
Based on the forecast track, Bising will move generally northeastward on Thursday, away from Luzon landmass before turning east northeastward on Friday, April 23, and generally eastward on Saturday April 24.
PAGASA said the tropical cyclone is forecast to exit the country’s area of responsibility on Saturday evening or Sunday early morning, April 25.
“Bising will gradually weaken throughout the remainder of the forecast period,” the agency said.
“It is forecast to be downgraded to severe tropical storm category by (Friday) and tropical storm category by Saturday before transitioning into an extratropical cyclone outside the PAR on Monday,” it added.
Areas under tropical wind signal number 1 are Batanes and the northeastern portion of Cagayan, including Babuyan Islands.
“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,” it said.
By Friday, Bising will likely be 665 km East Northeast of Itbayat, Batanes, and may be located 1,045 km East Northeast of Extreme Northern Luzon by Saturday morning before leaving PAR.
On Sunday morning, the typhoon may be 1,660 km East of Extreme Northern Luzon, outside PAR, and around 2,550 km East Northeast of Extreme Northern Luzon by Monday morning.
