Typhoon Bising

Typhoon Bising: In a weather bulletin issued by the Department of Science and Technology (DOST PAGASA) as of April 17, 5am, typhoon ‘Bising’ continues to rapidly intensify while moving west-northwestward over the Philippine Sea. Here are its updates:

Hazards affecting land areas

Heavy Rainfall: Tomorrow (18 April), the rainbands of Typhoon “BISING” 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.

Tropical Cyclone Wind Signal (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 Typhoon “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.

Track and Intensity Outlook

Typhoon “BISING” will move generally west-northwestward or northwestward over the Philippine Sea until tomorrow afternoon or evening. Afterwards, the typhoon will slow down and move northward or north-northeastward until Tuesday (20 April) early morning before moving north-northwestward over the Philippine Sea east of Northern and Central Luzon.

Owing to favorable atmospheric and oceanic conditions, “BISING” has rapidly intensified over the past 24 hours. It is forecast to further intensify and reach its peak intensity (195 to 205 km/h) tomorrow.

Location of eye/center: At 4:00 AM today, the center of the eye of Typhoon “BISING” was estimated based on all available data at 705 km East of Surigao City, Surigao del Norte or 775 km East of Maasin City, Southern Leyte (10.3°N, 131.9°E).

  • Strength: Maximum sustained winds of 175 km/h near the center and gustiness of up to 215 km/h.
  • Movement: Moving West Northwestward at 20 km/h.
