The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) is monitoring a new low pressure area (LPA) that has formed inside the country’s area of responsibility on Monday afternoon.

The weather disturbance was estimated at 640 kilometers east of Guiuan, Eastern Samar around 3 p.m. but has no direct effect yet over any part of the country as of Monday.

The intertropical convergence zone (ITCZ), where the LPA is embedded, and the warm easterly winds, remain the dominant weather systems across the country.

PAGASA said scattered rains and thunderstorms due to the ITCZ may persist across Palawan, Visayas, and Mindanao.

Meanwhile, the easterlies may bring partly cloudy to cloudy skies with isolated rain showers or thunderstorms over Metro Manila and the rest of the country.

According to weather specialist Robb Gile, PAGASA is not ruling out the possible formation of the LPA into a tropical depression.

But even if it does not develop into a tropical cyclone, Gile said some parts of the country may still be affected by the combined effects of the LPA and ITCZ as the week progresses.

Mindanao may be affected by the combined rains of LPA and ITCZ by Tuesday until Wednesday. It will likely approach Visayas and may also bring rains over parts of the region before further going up towards Luzon by Wednesday until Thursday.

PAGASA stations in the western section of the country are being monitored to confirm the onset of the rainy season over areas under the Type I climate or areas with distinct wet and dry seasons.

For the rainy season to be officially declared, two criteria have to be met–a total rainfall amount of 25 millimeters (mm) or more with three consecutive days having at least 1 mm of rainfall per day in at least seven out of 14 stations monitored by PAGASA, and the prevailing winds should have westerly components over the western Philippines relative to the rain-associated weather patterns.
