Typhoon “Bising” has slightly weakened and decelerated while churning over the Philippine Sea east of Catanduanes, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said Sunday, April 18.


In its 5 p.m. severe weather bulletin, PAGASA said the typhoon was located at 290 kilometers east of Virac, Catanduanes at 4 p.m., packing a maximum sustained winds of 205 kilometers per hour (kph) near the center and gustiness of up to 250 kph, while moving west northwestward at 15 kph.

PAGASA said moderate to heavy, with at times intense rains would be felt over Eastern Visayas and Bicol Region Sunday.

By Monday, April 19, moderate to heavy, with at times intense rains would be experienced over Bicol Region and Northern Samar.

Signal No. 2 remained hoisted over Catanduanes, Northern Samar, Eastern Samar, and Samar.

Signal No. 1 is still up in the eastern portion of Camarines Norte, Camarines Sur, Albay, Sorsogon, Masbate including Burias and Ticao Islands, Biliran, Leyte, Southern Leyte, northern portion of Cebu including Bantayan and Camotes Islands, Dinagat Islands, Siargao Islands, and Bucas Grande Islands.

‘Bising’ track outlook

The typhoon is forecast to start moving slowly northwestward over the Philippine Sea east of Bicol Region until Monday early morning.

It will then move generally northward until Tuesday afternoon, April 20, before turning north-northwestward while over the Philippine Sea east of Cagayan Valley.

By Wednesday early morning, April 21, the typhoon is forecast to turn northeastward or east northeastward away from the landmass of Luzon.

The state weather bureau has not yet ruled out the possibility of a close approach scenario, but it noted that the typhoon is forecast to gradually weaken throughout the forecast period.

“Considering the uncertainty in the track forecast of the typhoon, a westward shift in the current forecast track may result in potentially significant impacts over the eastern portions of Southern Luzon and Visayas,” it said.

Bising will likely be at 555 km east of Infanta, Quezon by Monday; 500 km east of Casiguran, Aurora by Tuesday; 495 km east of Aparri, Cagayan by Wednesday, April 21; 490 km East of Basco, Batanes by Thursday, April 22; and 945 km east northeast of Itbayat, Batanes by Friday, April 23.

24-hour weather forecast

In its 4 p.m. weather update, PAGASA said Catanduanes and Samar provinces would have stormy weather conditions due to the typhoon, while the rest of Bicol Region and Eastern Visayas may experience rains with gusty winds.

Residents in the areas were warned of possible light to moderate damage to structures and vegetation due to strong winds, as well as flash floods or landslides due to moderate to heavy rains.

Cloudy skies with scattered rain showers and thunderstorms may be felt in Northern Mindanao, Caraga, Southern Quezon, Marinduque, Romblon, and the rest of Visayas due to Bising.

Meanwhile, Cagayan Valley and Cordillera Administrative Region (CAR)  may have cloudy skies with rains due the combined effects of the weather disturbance and northeasterly windflow.

On the other hand, Metro Manila and the rest of the country may experience partly cloudy to cloudy skies with isolated rain showers due to localized thunderstorms.
