Eastern Visayas and the eastern and southern portions of Mindanao may experience light to at times heavy rains within 24 hours due to the combined effects of rain-bearing weather systems prevailing across the country.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) last spotted the low pressure area (LPA) at 90 kilometers southeast of Zamboanga City around Monday noon.

Although the LPA is less likely to become a tropical depression within the next 48 hours, PAGASA said its effect combined with the tail-end of frontal system and intertropical convergence zone may bring moderate to heavy rains over Agusan del Norte, Agusan del Sur, Dinagat Islands, Surigao del Norte, Surigao del Sur, Davao de Oro, Davao del Norte, Davao del Sur, Davao Oriental, Davao Occidental, South Cotabato, Cotabato, Sultan Kudarat, Sarangani, Biliran, Leyte, Northern Samar, Samar, Eastern Samar, and Southern Leyte.

Light to moderate with at times heavy rains may also prevail over Quezon, Palawan, Albay, Catanduanes, Camarines Norte, Camarines Sur, Sorsogon, Masbate, and the rest of Visayas and Mindanao.

PAGASA said the surge of the northeast monsoon or “amihan” will also bring scattered rains over Cagayan and eastern Isabela.

Flooding, including flash floods, and rain-induced landslides may occur during heavy or prolonged periods of rainfall, especially in areas that are highly susceptible to these hazards, PAGASA warned.

Likewise, it said adjacent or nearby areas that may not have been directly affected by the rainfall were urged to remain alert due to the possibility of flooding from surface runoff or swelling of river channels.

Due to the surge of amihan, sea travel remains risky over the northern, western, and eastern seaboards of Northern Luzon, western coast of Central Luzon, western and eastern seaboards of Southern Luzon, and eastern coastline of Visayas.

Fishing boats and other small sea vessels were advised to prevent from travelling out to sea, while larger sea vessels were asked to remain alert against big waves due to risky sea travel over these waters.
