Typhoon Bising 2021 signal

Hazards affecting land areas

Heavy Rainfall: Tomorrow (April 18), the rainbands of the typhoon will bring moderate to heavy with at times intense rains over Eastern Visayas, Sorsogon, Masbate, Albay, Camarines Sur, Catanduanes, and Camotes Islands.

Under these conditions, flooding (including flashfloods) and rain-induced landslides may 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 550 km from the center of the typhoon. Destructive typhoon-force winds extend outward up to 50 km from the center of the typhoon.

TCWS #1 may be hoisted over the eastern portion of Masbate, the northern portion of Cebu, and the other localities of Albay and Camarines Sur in the next bulletin in anticipation of the onset of strong breeze to near gale conditions associated with the approaching 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

Today, rough to very rough seas due to 'Bagyong Bising' will be experienced over the eastern seaboards of Bicol Region (2.5 to 4.5 m), Eastern Visayas (2.5 to 6.5 m), Caraga (2.5 to 5.5 m) and Davao Region (2.5 to 3.0 m). Sea travel for all types of seacrafts is risky over these waters.

'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.
