PAGASA warns: Heavy rains, flash floods, landslides from 3 weather systems

Overcast skies and rains are expected across many parts of the Philippines on Friday due to three weather systems: a shear line affecting Southern Luzon and Visayas, a northeast monsoon ('amihan') impacting the rest of Luzon, and easterlies prevailing over Mindanao.

Visayas, MIMAROPA, Bicol Region, Northern Mindanao, Caraga, Zamboanga Peninsula, Quezon, and Davao Oriental will see cloudy skies with scattered rains and isolated thunderstorms due to the shear line, potentially leading to flash floods or landslides from moderate to heavy rainfall.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) forecast heavy to intense rains over Sorsogon, Northern Samar, Eastern Samar, Southern Leyte, Dinagat Islands, Surigao del Norte, and Surigao del Sur due to the shear line.

Basilan, Sulu, and Tawi-Tawi are forecasted to experience cloudy skies with scattered rains and thunderstorms due to the easterlies, posing a risk for flash floods or landslides during severe thunderstorms.

Metro Manila, Cagayan Valley, Cordillera Administrative Region, the rest of CALABARZON, and Aurora will have cloudy skies with moderate to heavy rainfall from the northeast monsoon, which could lead to flash floods or landslides.

PAGASA warns that strong winds and rough coastal waters will prevail across the northern and eastern sections of Luzon, while moderate to strong winds and moderate to rough seas are expected in the rest of Mindanao and Visayas.
