Two low pressure areas (LPAs) in the east of the country have the possibility of developing into tropical depressions in the next few days, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Monday afternoon, Oct. 10.

In the PAGASA’s bulletin, the LPA inside the Philippine area of responsibility (PAR) was last seen 405 kilometers (km) east of Casiguran, Aurora at around 3 p.m.

The other LPA remains outside the PAR or about 1,770 km east of Visayas.

In a weather update through PAGASA’s official social media page, weather specialist Grace Castañeda said that the LPA east of Luzon has a chance of becoming a tropical depression within 48 hours, while the LPA east of Visayas is also possible to become a tropical cyclone in the next few days.

The next tropical cyclone names on the PAGASA’s list are Maymay and Neneng.

In the next 24 hours, cloudy skies with scattered rain showers and thunderstorms will prevail over some areas in Northern Luzon due to the trough of an LPA and shear line.

The trough or extension of the LPA east of Luzon and shear line—a region where warm and cold winds converge—will bring scattered rain showers and thunderstorms over Batanes, Cagayan, Isabela, Apayao, Abra, Kalinga, Mountain Province, and Ilocos Norte.

PAGASA advised those in these areas to be vigilant against possible flash floods or landslides during moderate to heavy rains.

Meanwhile, the rest of the country, including Metro Manila, will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms.

The public is also advised to stay vigilant against possible flash floods or landslides during severe thunderstorms, which are often accompanied by sudden heavy rains, lightning, thunder, gusty winds, and sometimes hail.

Castañeda said the LPA east of Visayas has no direct effect yet on the country.

However, this weather disturbance may enter the PAR within the next two to three days, she added.
