MANILA (Updated, 7:20 p.m.) -- Fourteen areas in Luzon are now under storm warning signal number 1 as Tropical Depression “Isang” slightly intensified Tuesday afternoon while moving toward Isabela-Cagayan, the country's weather agency reported.

Placed under storm warning signal number 1 are the provinces of Aurora, Quirino, Isabela, Ifugao, Mt. Province, Abra, Kalinga, Apayao, Ilocos Norte, Ilocos Sur, Cagayan, Calayan Group of Islands, Babuyan Group of Islands and Batanes Group of Islands.

Isang, the ninth cyclone to visit the country this year, was located at 230 kilometers east northeast of Baler, Aurora as of 4 p.m. Tuesday, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration's (Pagasa) 5 p.m. weather bulletin.

Pagasa warned residents living in areas under storm signal number 1, especially those living in low lying and mountainous places, to be vigilant against possible flashfloods and landslides.

Estimated rainfall amount is from five to 15 millimeters per hour (moderate - heavy) within the 300 kilometers diameter of Isang, said the weather bureau.

The tropical depression will enhance the southwest monsoon, which will bring light to moderate rains and thunderstorms over Mimaropa, Calabarzon, Bicol Region and Western Visayas.

Pagasa expects Isang to be at the vicinity of Cagayan by Wednesday afternoon, 380 kilometers northwest of Aparri, Cagayan by Thursday afternoon and 700 kilometers northwest of Aparri by Friday afternoon.

Meanwhile, Pagasa forecasts 13 to 19 tropical cyclones in the country between July and December this year.

Citing Pagasa's latest outlook, State weather specialist Anthony Lucero said the agency expects three or four tropical cyclones this July, two or three tropical cyclones in August and three or four tropical cyclones in September.

He also said Pagasa expects two or three tropical cyclones in October and the same count in November as well as one or two tropical cyclones in December. (Sunnex/PNA)
