A tail-end of a frontal system is affecting Southern Luzon, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration.
It is forecast to spawn moderate with at times heavy rains over Bicol, and Quezon, including Pollilo Islands.
Meanwhile, Metro Manila, MIMAROPA, the Visayas, Mindanao, Aurora, Nueva Ecija, Bulacan and the rest of CALABARZON will have scattered light to moderate rains.
Pagasa warned that flooding, including fals floods, and rain-induced landslides may occur during heavy or prolonged periods of rainfall, especially in areas identified to be highly susceptible to such hazards or in localities that received significant amount of rainfall over the past couple of days or weeks.
Adjacent or nearby areas may also experience floods in the absence of such rainfall occurrence due to surface runoff or swelling of river channels.
“The public and disaster risk reduction and management offices concerned are advised to take appropriate measures and watch for the next update on these weather systems…,” Pagasa said.
Meanwhile, the Office of Civil Defense (OCD) in Bicol said Sunday it was verifying reports of two deaths after bad weather triggered flooding and caused a boat to capsize in the region.
In a report, the OCD said it was validating the reported deaths of a 3-year-old boy who drowned after their boat capsized in Camarines Sur last Dec. 30, and of a 28-year-old man from Pilar, Sorsogon who was washed away by floods.
Bicol region has been experiencing rains in the past days due to the tailend of a frontal system, which is also affecting parts of Visayas and Mindanao.
Meanwhile, the OCD also reported that 2 unidentified individuals are missing after their boat capsized in Garchitorena town, Camarines Sur last Dec. 31.
There is another missing individual in Garchitorena, who may have drowned in the Ason river last Dec. 31, the OCD said.
Authorities are also conducting a search and rescue operation after a 13-year-old boy went missing in Bulan, Sorsogon, the agency added.
The OCD also recorded 24 landslide incidents in 15 municipalities and two cities in the region.
In a separate report, the National Disaster Risk Reduction and Management Council said rains prompted by the tail end of a frontal system triggered flooding in various parts of Cagayan Valley, Mimaropa, Bicol, and Western Visayas.
A boat capsized in the waters near Calapan City, Oriental Mindoro last Dec. 30, but authorities were able to rescue the 5 passengers, the NDRRMC said.
The weather disturbance has affected 2,409 families or 9,158 persons in Mimaropa, Bicol and Western Visayas, according to the NDRRMC.
Of the figure, 562 families were brought to evacuation centers while 450 opted to stay with relatives.
Fifty-four houses in Bicol and Western Visayas were damaged because of the bad weather, the NDRRMC said.
The NDRRMC also reported that 19 road sections and 3 bridges in Cagayan Valley, Mimaropa, Bicol, and Western Visayas are not passable to motorists due to damage, landslide or flooding.
PAGASA earlier said eastern portions of the country would continue to experience frequent rain until March due to the La Niña phenomenon.
In other reports, a total of 9,158 persons or 2,409 families were affected by the flooding and landslides due to the tail-end of a frontal system, the NDRRMC said in a report on Sunday.
