Typhoon Bising slightly weakened on Sunday and is forecast to leave the Philippine Area of Responsibility (PAR) on Wednesday, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

Bising was tracked by the weather bureau moving west northwestward at 15 kph. It had maximum sustained winds of 205 kph near the center and gustiness of up to 250 kph.

“Today (Sunday), Typhoon Bising will begin to move slowly northwestward over the Philippine Sea east of Bicol Region until tomorrow (Monday) early morning. The typhoon will then move generally northward until Tuesday (April 20) afternoon before turning north northwestward while over the Philippine Sea east of Cagayan Valley,” PAGASA said.

The weather bureau sees Bising moving out the country by the middle of next week.

“By Wednesday early morning, the typhoon is forecast to turn northeastward or east northeastward away from the landmass of Luzon,” it added.

PAGASA said Bising will bring moderate to heavy with at times intense rains over Bicol Region and Northern Samar tomorrow (Monday).

However, it added Bising’s uncertain track might result  in the typhoon affecting parts of Southern Luzon and Visayas while it is inside the PAR.

“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. The possibility of a close approach scenario is not ruled out,” PAGASA said.
