Luzon, Visayas warned of floods, landslides
2 areas under storm signal
MANILA - Tropical storm "Isang" gained strength on Monday and may further intensify into a severe tropical storm, warned state weather bureau PAGASA.
At 11 a.m., Isang was packing top sustained winds of 80 kilometers per hour (kph), up from 65 kph; and gusts of up to 97 kph, said PAGASA meteorologist Aldczar Aurelio.
Starting Monday night, habagat rains may trigger floods and landslides in low-lying areas, said Aurelio.
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 the Babuyan Islands.
"Bukas ng umaga, lalakas siya at aabot sa kanyang intensity na severe tropical storm," Aurelio said in a press briefing.
(It will continue to strengthen on Tuesday and its intensity may reach severe tropical storm.)
Isang, he added, is set to enhance the southwest monsoon or habagat, which will bring moderate to occasionally heavy rains in the western section of Luzon and Visayas.
Isang was last spotted 275 kilometers east of Basco, Batanes.
If the storm continues moving at 17 kph, it may leave the Philippine area of responsibility between late Tuesday and early Wednesday.
