In the 11 a.m. severe weather bulletin issued by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the center of the eye of typhoon Bising was estimated 475 kilometers east of Infanta, Quezon around 10 a.m.

Bising remains a threat as it maintained its pace while packing maximum sustained winds of 175 kilometers per hour (kph) near the center and gustiness of up to 215 kph.

The cyclone’s outer rainbands is expected to continue to bring moderate to heavy rains over Catanduanes, and light to moderate to at times heavy rains over the eastern portion of Quezon, Camarines Norte, Camarines Sur, Sorsogon, Albay, and Northern Samar Tuesday.

PAGASA warned of possible flooding or flash floods and rain-induced landslides in areas that are highly susceptible to these hazards.

Tropical cyclone wind signals still up

Storm signals in some areas have been lifted or downgraded but several areas remain under Signal No. 2 and Signal No. 1 on Tuesday morning.

The eastern portion of Cagayan, eastern portion of Isabela, and Catanduanes were still under Signal No. 2.

Meanwhile, Signal No. 1 remain hoisted over Batanes, rest of Cagayan including Babuyan Islands, rest of Isabela, Quirino, Apayao, eastern portion of Kalinga, eastern portion of Mountain Province, eastern portion of Ifugao, northern portion of Aurora, eastern portion of Quezon including Polillo Islands, Camarines Norte, Camarines Sur, Albay, Sorsogon, Northern Samar, northern portion of Samar, and northern portion of Eastern Samar.

In the next 24 hours, Bising may trigger very rough to high seas over the northern and eastern seaboards of Luzon with wave heights up to 4.5-10.0 meters (m) and rough to high seas over the northern and eastern seaboards of Eastern Visayas (3.0-7.0 m).

Rough to very rough seas may also prevail over the western seaboards of Northern Luzon (2.8 to 4.5 m), and rough seas over the eastern seaboards of Caraga and Davao Oriental and the remaining seaboards of areas with wind signals.

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

Projected track and intensity

Typhoon Bising is expected to continue to move generally north or north-northwest until Wednesday evening, April 21 or Thursday morning, April 22, PAGASA said.

Afterward, the typhoon will begin to move northeast away from the Luzon landmass throughout Thursday, then move east-northeast by Friday, April 23 until Saturday, April 24, and exit the Philippine area of responsibility by Sunday, April 25.

PAGASA said Bising will gradually weaken throughout the forecast period and may be downgraded to severe tropical storm between Saturday evening and Sunday morning.

Bising will likely be at 340 km east of Tuguegarao City, Cagayan by Wednesday morning; 290 km east-northeast of Aparri, Cagayan by Thursday morning; 510 km east of Basco, Batanes by Friday morning; 1,020 km east of extreme Northern Luzon by Saturday morning; and 1,565 km east-northeast of extreme northern Luzon by Sunday morning.
