MANILA - State weather bureau PAGASA said Wednesday morning that warning signal no. 4 remains hoisted over the Batanes group of islands as Typhoon Ferdie made landfall in the area.

PAGASA said warning signal no. 3 is up in the Babuyan group of islands, while signal no. 2 is up in Ilocos Norte, Apayao and northern Cagayan.

Meanwhile, tropical cyclone warning signal no. 1 is up in the rest of Cagayan, Kalinga, Abra and northern Ilocos Sur.

In a weather bulletin issued at 5:00 a.m., PAGASA said Ferdie was packing maximum sustained winds of up to 220 kilometers per hour and gusts of 255 kph.

It is expected to move west-northwest at 22 kph.

The eye of Typhoon Ferdie was located 45 kilometers northwest of Itbayat, Batanes at 4 a.m. Wednesday.

Residents in northern Luzon were advised to take precautionary measures against impacts of very strong winds and heavy rainfall.

Areas under warning signals were warned of possible storm surge in coastal areas.

PAGASA expects Ferdie to leave the Philippine area of responsibility (PAR) between 10 a.m. to 12 p.m. Wednesday.

Meanwhile, another typhoon has entered PAR.

Typhoon Gener was packing maximum sustained winds of up to 130 kph and gusts of 160 kph. It is expected to move west-northwest at 24 kph.

Gener is also expected to enhance the rains brought by the southwest monsoon (habagat).

Despite being inside the PAR at the same time, Ferdie and Gener will not have an effect on each other.
