MANILA – "Karding" intensified into a severe tropical storm and is forecast to strengthen into a typhoon before making landfall over Central or Northern Luzon, the weather bureau reported on Saturday.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), in its early morning update, said "Karding" was likely to make landfall Sunday morning or afternoon on the east coast of Aurora or Isabela.

Tropical Cyclone signal no. 2 is up over the southeastern portion of Isabela (Dinapigue), the northern portion of Aurora (Dinalungan, Casiguran, Dilasag), and Polillo Islands.

These areas will experience winds of greater than 61 kilometers per hour (kph) and up to 120 kph may be expected in at least 24 hours.

Tropical Cyclone signal no. 1 is hoisted over the southern portion of Cagayan (Peñablanca, Iguig, Tuguegarao City, Enrile, Solana, Tuao, Piat, Amulung, Rizal), the rest of Isabela, Quirino, Nueva Vizcaya; the southern portion of Apayao (Conner), Abra, Kalinga, Mountain Province, Ifugao, Benguet, the southern portion of Ilocos Norte (Nueva Era, Badoc, Pinili, Banna, City of Batac, Currimao, Paoay, Marcos), Ilocos Sur, La Union, Pangasinan, the rest of Aurora, Nueva Ecija, Tarlac, Bulacan, Pampanga, Zambales, Bataan, Metro Manila, the northern and central portions of Quezon (Tagkawayan, Lopez, Guinayangan, Gumaca, Pitogo, Unisan, Agdangan, Padre Burgos, Pagbilao, City of Tayabas, Lucban, Sampaloc, Mauban, Atimonan, Plaridel, Perez, Alabat, Quezon, Calauag, Lucena City, General Nakar, Real, Infanta), Rizal, Laguna, Cavite, the northern portion of Batangas (Malvar, Balete, City of Tanauan, Santo Tomas, Talisay, Laurel), Camarines Norte, northern and eastern portions of Camarines Sur (Del Gallego, Ragay, Lupi, Sipocot, Siruma, Tinambac, Goa, Lagonoy, Garchitorena, Caramoan, Presentacion, San Jose), and the northern portion of Catanduanes (Pandan, Caramoran, Bagamanoc, Panganiban, Viga, Gigmoto).

These areas will be hit by winds of 30-60 kph may be expected in at least 36 hours or intermittent rains may be expected within the same period.

PAGASA said while it was likely for "Karding" to slightly weaken due to land interaction while traversing Northern and Central Luzon, it was to remain a typhoon while crossing the landmass. (PNA)
