PAGASA - Typhoon "Bising" slightly decelerates over the Philippine Sea east of Northern Samar while maintaining its strength. The rain bands of Typhoon “BISING” will bring moderate to heavy with at times intense rains over Eastern Visayas and Bicol Region today.
Tomorrow (19 April), moderate to heavy with at times intense rains will be experienced over Bicol Region, Northern Samar, Samar, and Eastern Samar.
Under these conditions, flooding (including flashfloods) and rain-induced landslides are likely to occur especially in areas identified in hazard maps as highly or very highly susceptible to these hazards.
Tropical cyclone winds of at least strong breeze to near gale in strength extend outward up to 440 km from the center of the typhoon. Destructive typhoon-force winds extend outward up to 110 km from the center of the typhoon.
Based on the current forecast scenario, TCWS #2 remains the highest level of wind signal that will be hoisted due to this typhoon. However, in the event of a further eastward or westward shift in the current track forecast, highest level of wind signal that will be hoisted for this typhoon may be lower or higher than the current scenario suggests.
Typhoon “BISING” will continue moving northwestward over the Philippine Sea east of Bicol Region today and is likely to slow down considerably and begin turning more northward tonight or tomorrow early morning.
The typhoon will then continue moving northward until Tuesday (20 April) morning before turning north northwestward while over the Philippine Sea east of Cagayan Valley. By Wednesday evening or Thursday early morning, the typhoon is forecast to turn northeastward or east northeastward away from the landmass of Luzon.
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.
The typhoon is forecast to maintain its strength today before gradually weakening throughout the remainder of the forecast period. - (Issued at 05:00 am, 18 April 2021. Valid for broadcast until the next advisory to be issued at 11 AM today)
