(UPDATED) Tropical storm "Isang" continues to move towards Batanes, state weather bureau PAGASA said Monday night.
In its 11 p.m. advisory, PAGASA said Isang was packing maximum sustained winds of 80 kilometers per hour (kph), and gusts of up to 97 kph.
It is expected to move west at 17 kph.
Tropical storm signal no. 2 was raised over the Batanes islands, where storm surges could hit coastal areas. Signal no. 1 meanwhile was raised over Northern Cagayan including Babuyan group of islands, Apayao, and Ilocos Norte.
PAGASA said Isang will continue to bring rains to mainland northern Luzon and other parts of Luzon and Visayas, as it enhances the southwest monsoon or habagat.
"Ang katangian po ni isang, 'yung kanyang paulan, nauuna. Kaya pagdating po nung kanyang sentro dito sa may Batanes, mostly puro hangin po ito. Pero 'yung kaulapan niya, magpapaulan po dito sa mainland northern Luzon," Peñaranda said.
Isang was last spotted 80 kilometers east of Basco, Batanes.
It is expected to exit the Philippine area of responsibility between late Tuesday and early Wednesday.
