MANILA — The state weather bureau escalated its rainfall alert to yellow status over four Luzon provinces on Monday morning, citing sustained moisture inflow from the southwest monsoon system locally called habagat combined with the presence of a tropical depression.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration issued the upgraded warning based on its 11 a.m. weather assessment. The yellow alert indicates moderate rainfall conditions that may impact the affected areas over the coming hours.

Tropical Depression Pilandok is enhancing the effects of the habagat, creating conditions conducive to heavier precipitation across the region. Residents in the affected provinces are advised to monitor further weather updates as conditions may develop.

The yellow rainfall warning represents the second-highest alert level in the nation's weather warning system, signaling the potential for significant moisture accumulation and localized flooding in vulnerable areas. Authorities have begun coordinating preparedness measures in anticipation of the rainfall event.
