State weather forecasters on Monday warned of more heavy rain over Metro Manila and nearby provinces Monday.
At 5:45 a.m., PAGASA issued an orange rainfall advisory, warning of "heavy to at times intense rainfall" over Metro Manila, Rizal, Bulacan, Pampanga, Zambales, Bataan and parts of Laguna, Quezon, Cavite, and Occidental Mindoro.
Meanwhile, PAGASA forecaster Manny Mendoza reported of an approaching tropical storm, internationally codenamed Pabuk, which may enter the Philippine Area of Responsibility (PAR) as early as Wednesday.
"Pag pumasok ito sa PAR, papangalanin nating Paolo. Ito ang humahatak ng habagat, medyo malakas na itong bagyong ito," he said in an interview on dzBB radio.
He said the southwest monsoon is the cause of the heavy rain over Metro Manila and other parts of Luzon since Sunday. The downpour has caused floods in several areas and prompting the suspension of classes.
For now, Mendoza said Pabuk is south of Japan. The Japan Meteorological Agency said Pabuk is heading north-northwest.
Mendoza also said they are tracking a potential low-pressure area at the East Philippine Sea.
PAGASA, in its 5 a.m. bulletin, said the southwest monsoon continues to affect southern Luzon and Visayas.
"Metro Manila, Central Luzon and Calabarzon will experience cloudy skies with moderate to occasionally heavy rains and thunderstorms which may trigger flash floods and landslides."
Mimaropa and Bicol will have "cloudy skies with light to moderate rainshowers and thunderstorms."
Also, northern Luzon, Visayas and Mindanao will be "partly cloudy to cloudy with isolated rainshowers or thunderstorms."
Moderate to strong winds from the southwest will prevail throughout the entire archipelago and the coastal waters will be moderate to rough. — DVM/TJD, GMA News
