MANILA, Philippines – Signal No. 1 was raised in several areas late Thursday morning, August 22, as Tropical Storm Ineng (Bailu) slightly intensified.

In a bulletin issued 11 am on Thursday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Ineng now has maximum winds of 75 kilometers per hour (km/h) from the previous 65 km/h and gustiness of up to 90 km/h from the previous 80 km/h.

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

Ineng is already 725 kilometers east of Casiguran, Aurora, still moving west northwest at 15 km/h.

Signal No. 1 is now up over:

Batanes

Cagayan including Babuyan Group of Islands

Isabela

Apayao

Kalinga

northern part of Abra

Ilocos Norte

Areas under Signal No. 1 can expect winds of 30 km/h to 60 km/h and intermittent rain in at least 36 hours. Tropical cyclone wind signals are raised even before the effects of a tropical cyclone are felt, giving residents enough time to prepare.

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.

The country gets an average of 20 tropical cyclones annually, but since 2019 is an El Niño year, only 14 to 18 tropical cyclones are expected.

Below is the estimated number of tropical cyclones from August to December:

August - 2 to 4

September - 2 to 4

October - 2 or 3

November - 1 or 2

December - 0 or 1
