PAGASA warns heavy rains, flooding in 27 provinces through Wednesday

A shear line affecting Southern Luzon and Visayas, along with the Northeast Monsoon (amihan) impacting the rest of Luzon, is expected to bring heavy rains over several areas through Wednesday, according to PAGASA's weather forecast.

Visayas, Bicol Region, MIMAROPA, Quezon, Aurora, Caraga, Davao, and parts of Mindanao will experience cloudy skies with scattered rains and isolated thunderstorms due to the shear line and easterlies, respectively.

PAGASA placed 17 provinces under heavy rainfall outlook from Monday until Tuesday noon, with nine provinces expecting heavy to intense rainfall ranging from 100 to 200 millimeters (mm), likely causing numerous flooding events in urbanized or low-lying areas and landslides in moderate to highly susceptible regions.

Eight additional provinces were placed under moderate to heavy rainfall warning, where 50 to 100 mm of rain is expected during the same period, potentially leading to flash floods or landslides.

Metro Manila, Cagayan Valley, Cordillera Administrative Region, Cavite, Batangas, and the rest of Central Luzon will have cloudy skies with scattered rains and thunderstorms brought about by the Northeast Monsoon. Moderate to heavy rainfall may trigger flash floods or landslides.

The amihan is expected to bring partly cloudy to cloudy skies with isolated light rain to the rest of Luzon, while easterlies will cause cloudy skies with scattered rain showers and thunderstorms in Caraga and Davao Region.
