The country is likely to experience rainy weather for the rest of the week due to the combined effects of the shear line and intertropical convergence zone (ITCZ), according to state weather bureau PAGASA on Wednesday.
Both weather disturbances brought moderate to heavy rains across Metro Manila and Luzon provinces on Christmas Day, including Bulacan, Cavite, Laguna, Batangas, Rizal, Albay, Sorsogon, Masbate, Marinduque, Romblon, Oriental Mindoro and Northern Samar.
PAGASA forecast a heavy to intense rainfall outlook over Aurora, Quezon, Camarines Norte, Camarines Sur, and Catanduanes which will prevail from Thursday afternoon until noon on Saturday, covering Isabela and Cagayan provinces.
Rains are also expected in Apayao, Dinagat Islands, Surigao del Norte, Surigao del Sur, and Davao Oriental towards the weekend. PAGASA warned of possible flooding and incidents of landslides in all affected areas.
PAGASA earlier issued a weather advisory warning against the impact of a shear line weather system currently affecting Southern Luzon. This system is anticipated to bring substantial rainfall to the Bicol Region, particularly in Albay Province, over the coming days.
The Department of Science and Technology-Philippine Institute of Volcanology and Seismology (DOST-PHIVOLCS) warns that the expected heavy rains could trigger volcanic sediment flows, known as lahars, which pose significant risks to communities situated near Mayon Volcano.
DOST-PHIVOLCS stressed the importance of monitoring weather conditions and implementing preemptive safety measures to mitigate potential hazards.
In addition to the shear line's effects, the northeast monsoon is influencing other regions, resulting in cloudy skies and isolated rain showers. The affected regions include Cagayan Valley and Cordillera Administrative Region.
Heavy to intense rainfall will prevail today (Thursday) in Aurora, Quezon, Camarines Norte, Camarines Sur, Isabela and Cagayan until the weekend, PAGASA said.
Numerous flooding events are likely, especially in areas that are urbanized, low-lying or near rivers. Moderate to heavy rainfall will persist in Metro Manila, Bulacan, Cavite, Laguna, Batangas, Rizal, Albay, Sorsogon, Masbate, Marinduque, Romblon, Oriental Mindoro, Northern Samar, Cagayan, Apayao, Camarines Norte, Dinagat Islands, Surigao del Norte, Surigao del Sur and Davao Oriental.
