MANILA, Philippines – Tropical Storm Ineng (Bailu) slowed down again on Thursday afternoon, August 22, with 7 areas remaining under Signal No. 1.

In a bulletin issued 5 pm on Thursday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Ineng is already 670 kilometers east of Casiguran, Aurora.

It is now moving west northwest at 10 kilometers per hour (km/h) from the previous 15 km/h.

Ineng maintained its strength, with maximum winds of 75 km/h and gustiness of up to 90 km/h.

But it is expected to strengthen further into a severe tropical storm within 24 hours, while inside the Philippine Area of Responsibility (PAR).

Signal No. 1 remains raised in the following areas:

  • Batanes
  • Cagayan including Babuyan Group of Islands
  • Isabela
  • Apayao
  • Kalinga
  • northern part of Abra
  • Ilocos Norte

Signal No. 1 means winds of 30 km/h to 60 km/h. Tropical cyclone wind signals are issued based on wind and not on rainfall.

Ineng remains unlikely to make landfall, but it is enhancing the southwest monsoon or hanging habagat, which is another source of rain.

Below is the latest list of areas affected by either the tropical storm or the southwest monsoon, and the expected rainfall from both.

  • November – 1 or 2
  • December – 0 or 1
