The northeast monsoon and a shear line are expected to bring rain showers to many parts of Luzon, according to the latest report from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

As per the 4 a.m. weather bulletin, PAGASA anticipates moderate to heavy rainfall in the remaining areas of Cagayan Valley due to the northeast monsoon. This weather pattern may lead to potential flooding and landslides in these regions.

Scattered rain showers and thunderstorms, resulting from the shear line, are expected to affect Metro Manila, Central Luzon, Region 4-A (Calabarzon), Bicol Region, Isabela, Quirino, and Nueva Vizcaya.

In the Cordillera Administrative Region and Ilocos Region, the northeast monsoon will bring lighter rain showers.

The rest of the country should anticipate isolated rain showers brought about by localized thunderstorms.

Northern Luzon is likely to experience moderate to strong winds and moderate to rough seas, while other areas should expect lighter to moderate winds and slight to moderate sea conditions, according to PAGASA’s most recent forecast.

In its weather advisory No. 4 issued on Sunday, PAGASA also highlighted the shear line’s potential to bring a substantial amount of rainfall to Quezon and Camarines Norte over the next two days.
