MANILA -- Tropical Storm Jolina could dump moderate to heavy rains that could trigger landslides and flash floods in northern and central Luzon between Friday and Saturday.
'Jolina' will likely plow through and bring rains after it makes landfall in the Isabela-Aurora area Friday night, said weather forecaster Nikos PeAaranda of the state weather bureau, PAGASA.
"Rain from 'Jolina' can trigger landslides, particularly in the Northern Luzon-Central Luzon area's mountainous portions left saturated by precipitation of severe Tropical Storm 'Isang' (international name 'Hato') earlier," he said, warning that rains could cause some waterways in the region to overflow and result in floods.
In its Severe Weather Bulletin 15 released Friday, PAGASA located 'Jolina' at some 210 km. southeast of Aurora province's Casiguran municipality as of 10 a.m., packing maximum sustained winds of 80 kph near its center and gustiness of up to 95 kph.
"Land travel is risky, particularly in mountainous areas, due to possible landslides," noted PeAaranda, also cautioning against sea travel due to strong winds.
'Jolina', he said, could also bring light to moderate -- and at times heavy -- rains to Metro Manila and the Calabarzon region.
PAGASA, however, expects 'Jolina' rains to ease towards Sunday.
Latest data indicate 'Jolina' may exit Luzon landmass on Saturday morning and leave the Philippine Area of Responsibility (PAR) Saturday evening or early Sunday, PeAaranda said.
Tropical cyclone warning signal (TCWS) 2 is already prevailing in Isabela, Northern Aurora, Quirino, Kalinga, Mountain Province, Ifugao, Ilocos Sur, Benguet, Abra, La Union and Nueva Vizcaya, with 61 kph to 120 kph winds that could fan waves up to 14 meters high, noted PAGASA.
TCWS 1 is meanwhile prevailing in Cagayan including the Babuyan Islands, Apayao, the rest of Aurora, Ilocos Norte, Nueva Ecija, Pangasinan, Northern Quezon including Polillo Island, Catanduanes, Camarines Norte and Camarines Sur, where 30 kph to 60 kph winds can strike.
PAGASA forecast 'Jolina' to move west-northwest at 19 kph.
'Jolina' may be 545 km. west-northwest of Ilocos Norte province's capital Laoag City by Sunday morning, already outside PAR, added PAGASA.
