The typhoon will then continue moving northward until Tuesday (April 20) 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 north northeastward away from the landmass of Luzon.
PAGASA said the possibility of a close approach scenario is not ruled out 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.
At 4:00 am today, the center of the eye of Typhoon 'Bising' was located based on all available data at 400 km East of Catarman, Northern Samar or 470 km East of Juban, Sorsogon.
'Bagyong Bising' has maximum sustained winds of 215 km/h near the center and gustiness of up to 265 km/h. It is moving Northwestward at 15 km/h.

Hazards affecting land areas
Heavy Rainfall
Today, the rain bands of 'Bising' will bring moderate to heavy with at times intense rains over Eastern Visayas and Bicol Region.
Tomorrow (April 19), moderate to heavy with at times intense rains while 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.
Severe Winds
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.
Hazards affecting coastal waters
In the next 24 hours, under the influence of the typhoon and an enhanced northeasterly wind flow, the following sea conditions will be experienced over the coastal waters of the country:
Very rough to very high seas will be experienced over the northern and eastern seaboard of Eastern Visayas (4.0 to 12.0 m), rough to very high seas over the eastern seaboard of Luzon (2.5 to 12.0 m), and rough to very rough seas over the eastern seaboard of Caraga (3.0 to 5.0 m). Sea travel is risky for all types of seacrafts over these waters.
Rough to very rough seas over the northern and western seaboards of Northern Luzon (2.5 to 5.0 m) and rough seas over the eastern seaboard of Davao Region (2.5 to 3.5 m). Sea travel is risky for small seacrafts over these waters. Mariners without the proper experience should immediately seek safe harbor.
Moderate to rough seas over the western seaboard of Central Luzon and the remaining seaboards of localities where wind signals are in affect (1.5 m to 3.0 m). Mariners of small seacrafts are advised not to venture out over these waters. Inexperienced mariners of these vessels should avoid navigating in these conditions.
About the typhoon
'Bising' entered PAR on Friday morning, April 17.
PAGASA predicts that 1–4 tropical cyclones are expected to form between April and June.
On average, there are 20 tropical cyclones that could form or enter the PAR each year. Only have of those are projected to make landfall.
