Issued at 05:00 AM, 20 April 2021, TYPHOON "BISING" FURTHER WEAKENS AS IT CONTINUES TO MOVE SLOWLY NORTHWARD.
Hazards affecting land areas
Today (20 April), heavy to intense rains will be experienced over Catanduanes. Moderate to heavy rains over the eastern portion of Camarines Sur and Rapu-Rapu Islands. Under these conditions and considering the antecedent rainfall over the aforementioned areas, flooding (including flashfloods) and rain-induced landslides are highly 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.
Tropical cyclone winds of at least strong breeze to near gale in strength extend outward up to 500 km from the center of the typhoon. Destructive typhoon-force winds extend outward up to 110 km from the center of the typhoon.
Considering the uncertainty in the projected path of the typhoon over the next 48 hours, the possibility of hoisting Tropical Cyclone Wind Signal #2 over some areas in the eastern portion of Cagayan and Isabela is not ruled out at this time.
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 the rest of Northern Luzon and the rest of Aurora and 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 high seas over the northern and eastern seaboards of Luzon (4.5 to 10.0 m), and rough to high seas over the northern and eastern seaboards of Eastern Visayas (3.0 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 (2.8 to 4.5 m), and rough seas over the eastern seaboards of Caraga and Davao Oriental and the remaining seaboards of areas under TCWS (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.
Track and Intensity Outlook
On the forecast track, Typhoon “BISING” will move generally northward or north northwestward until Wednesday evening (21 April) or Thursday (22 April) early morning. Afterwards, the typhoon will move northeastward from the landmass of Luzon throughout Thursday and east northeastward to eastward on Friday (23 April) and Saturday (24 April). The typhoon is projected to exit the Philippine Area of Responsibility on Sunday (25 April).
The typhoon is forecast to gradually weaken throughout the forecast period and may be downgraded to severe tropical storm by Saturday evening or Sunday early morning.
At 4:00 AM today, the center of the eye of Typhoon "BISING" was located based on all available data at 505 km East of Infanta, Quezon (15.2 °N, 126.3 °E ).
