Typhoon Bising (Surigae) maintained its strength and slow pace on Monday afternoon, April 19, still affecting parts of Luzon and the Visayas due to its wide diameter.
The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said in its 5 pm bulletin on Monday that Bising was already 500 kilometers east of Infanta, Quezon, continuing to move north northwest slowly.
The state weather bureau earlier explained that Bising's slow movement is due to two high pressure areas – one on its left, the other on its right.
The typhoon continues to have maximum sustained winds of 195 kilometers per hour (km/h) and gustiness of up to 240 km/h, but it may eventually weaken in the coming days.
PAGASA maintained the following rainfall forecast for areas affected by Bising:
Monday, April 19
Tuesday, April 20
Those areas must stay on alert for floods and landslides. (READ: FAST FACTS: Tropical cyclones, rainfall advisories)
Tropical cyclone wind signals also remain in place. This is the list of areas covered as of 5 pm on Monday:
PAGASA said tropical cyclone winds that are "at least strong breeze to near gale in strength extend outward up to 440 kilometers" from Bising's center.
"Destructive typhoon-force winds," meanwhile, "extend outward up to 110 kilometers" from the center.
Bising also continues to enhance the northeasterly wind flow, which is bringing strong breeze to near-gale conditions to the following areas:
PAGASA said Bising is likely to keep moving north or north northwest until Wednesday evening, April 21, or early Thursday morning, April 22. After that, the typhoon would head northeast or east northeast, moving away from Luzon without making landfall.
Bising might leave the Philippine Area of Responsibility (PAR) on Saturday, April 24, or Sunday, April 25.
