The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) monitored a low pressure area (LPA) that formed outside the country’s area of responsibility (PAR) early Monday morning, Nov. 29.

PAGASA weather specialist Aldczar Aurelio said the LPA that is embedded within the intertropical convergence zone (ITCZ) was estimated 1,960 kilometers east of Mindanao at around 3 a.m.

He said the weather disturbance, which has a potential to develop into a tropical depression, may enter the Philippine area of responsibility by Tuesday, Nov. 30 or Wednesday, Dec. 1.

Since the LPA has no direct effect yet to any part of the Philippines, the shear line and ITCZ remain the dominant weather systems that may bring rains over several areas in the country.

In the next 24 hours, PAGASA said Batanes, Cagayan, and Isabela may have cloudy skies with scattered rains and thunderstorms due to the shear line, also known as the tail-end of the frontal system.

Cloudy skies with scattered rain showers and thunderstorms due to the ITCZ may prevail over Basilan, Sulu, Tawi-Tawi, Zamboanga Sibugay, Zamboanga del Norte, Zamboanga del Sur, Davao de Oro, Davao del Norte, Davao del Sur, Davao Oriental, and Davao Occidental.

Areas that will likely be affected by the shear line and ITCZ were warned against possible flash floods or landslides, especially in the event of moderate to, at times, heavy rains.

Meanwhile, Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers due to the easterlies and localized thunderstorms.

The State weather bureau, however, warned that severe thunderstorm activities may sometimes trigger flash floods or landslides.
