Tropical cyclone wind signal No. 1 may be raised over some areas in Cagayan Valley by Wednesday due to the possible landfall of tropical storm “Siony” (international name “Atsani”) this week, according to a State weather specialist.


Ana Clauren of the Philippine Atmospheric, Geophysical, and Astronomical Services Administration said Siony may make landfall over Cagayan Valley between Thursday evening and Friday, but the uncertainty still remains high as to the cyclone’s final track due to its erratic movement.

It could either move towards Batanes or northern tip of Cagayan, she said in a DZMM interview.

As of 3 p.m. Monday, Siony was 655 kilometers east of Calayan, Cagayan with maximum sustained winds of 65 kilometers per hour (kph) near the center and gustiness of up to 80 kph, moving north at 25 kph.

Clauren said Siony may either intensify into a severe tropical storm or weaken while approaching Northern Luzon.

Clauren advised the public, particularly, those in Cagayan Valley, Cordillera Administrative Region, and Ilocos region to monitor possible developments regarding this weather disturbance.

Meanwhile, tropical storm “Rolly” (international name “Goni”) was estimated at 225 kms west of Iba, Zambales with maximum sustained winds of 65 kph near the center and gustiness of up to 80 kph around 3 p.m.

Should it maintain its north-northwest track at 15 kph, Rolly will be outside the Philippine Area of Responsibility by Tuesday morning.

Scattered rain showers and thunderstorms due to the trough or extension of Rolly may prevail over Western Visayas, Zamboanga Peninsula, Zambales, Bataan, Occidental Mindoro, Palawan, Basilan, Sulu, and Tawi-Tawi.

The trough of Siony may also bring scattered rain showers over Cagayan Valley, Apayao, Kalinga, and Ilocos Norte.

Metro Manila and the rest of the country will be partly cloudy to cloudy with isolated rain showers due to localized thunderstorms.
