Hazards affecting land areas
Heavy Rainfall
Today, moderate to heavy with at times intense rains will be experienced over Bicol Region, Northern Samar, Samar, Eastern Samar, Biliran, and Leyte.
Tomorrow (April 20), moderate to heavy rains will be experienced over Bicol Region and Northern Samar.
Under these conditions and considering the antecedent rainfall over the aforementioned areas, flooding (including flashfloods) and rain-induced landslides are increasingly likely to occur especially in areas identified in hazard maps as highly or very highly susceptible to these hazards.
PAGASA Regional Services Divisions may issue local thunderstorm/rainfall advisories and heavy rainfall warnings while the Hydrometeorology Division and River Basin Flood Forecasting and Warning Centers may issue General Flood Advisories and Basin Flood Bulletins as appropriate.
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.
In the next 24 hours, the northeasterly wind flow enhanced by the typhoon will also bring strong breeze to near gale conditions with higher gusts over most of Northern Luzon, Aurora, and the rest of Quezon that are not under any Tropical Cyclone Wind Signal (TCWS). Such conditions are more likely to occur in the coastal and mountainous areas.
Hazards affecting coastal waters
In the next 24 hours, under the influence of Typhoon 'Bising' 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 eastern seaboard of Luzon (5.0 to 12.0 m) and rough to very high seas over the northern and eastern seaboards of Eastern Visayas (2.5 to 7.0 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 the eastern seaboard of Caraga (2.5 to 4.5 m) and rough seas over the remaining seaboards of localities where wind signals are in effect and the eastern seaboard of Davao Oriental (2.5 to 4.0 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 (1.2 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.
