MANILA, Philippines – Domeng (Jangmi) intensified from a severe tropical storm into a typhoon on Saturday afternoon, May 30, while staying offshore over the Philippine Sea.

In a bulletin issued at 5 pm on Saturday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Domeng now has maximum sustained winds of 120 kilometers per hour from the previous 100 km/h. Its gustiness is now up to 150 km/h from 125 km/h.

The typhoon was last spotted 815 kilometers east of Northern Luzon as of 4 pm, still moving northwest at 20 km/h.

Domeng is not expected to make landfall in the Philippines, and may eventually recurve towards Japan.

But the trough or extension of the typhoon is bringing scattered rain and thunderstorms to Batanes, Cagayan, Isabela, Aurora, and Quezon on Saturday evening. Flash floods and landslides are possible.

In addition, Domeng is enhancing the southwest monsoon, which is causing scattered rain and thunderstorms in Mimaropa, Batangas, Western Visayas, the Negros Island Region, Zamboanga Peninsula, Bangsamoro Autonomous Region in Muslim Mindanao, and Lanao del Norte on Saturday evening.

Rain from the enhanced southwest monsoon may worsen in the following provinces starting Sunday, May 31:

Sunday afternoon, May 31, to Monday afternoon, June 1

Moderate to heavy rain (50-100 millimeters): Palawan, Occidental Mindoro, Antique

Monday afternoon, June 1, to Tuesday afternoon, June 2

Moderate to heavy rain (50-100 mm): Bataan, Batangas, Palawan, Occidental Mindoro, Antique, Iloilo, Guimaras

Floods and landslides are possible.

Meanwhile, it remains “less likely” for tropical cyclone wind signals to be raised, given Domeng’s distance from land. But PAGASA is not ruling out the possibility of extreme Northern Luzon being placed under a wind signal.

The enhanced southwest monsoon and the periphery or outer bands of the typhoon will also bring strong to gale-force gusts to these areas:
