MANILA, Philippines - The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) warned Sunday that two weather systems - a low-pressure area (LPA) and the tail-end of a cold front - over the country may trigger floods and landslides in the entire Southern Luzon, Visayas, and parts of Northern and Eastern Mindanao.
Provinces that may be affected by floods and landslides if rains continue are Batangas, Cavite, Laguna, Quezon, Rizal, Marinduque, Occidental Mindoro, Oriental Mindoro, Palawan, and Romblon, all in the Southern Luzon; Aklan, Antique, Capiz, Guimaras, Iloilo, Negros Occidental, Bohol, Cebu, Negros Oriental, Siquijor, Biliran, Eastern Samar, Leyte, Northern Samar, Samar (Western Samar), and Southern Leyte, all in the Visayas; Surigao del Norte, Surigao del Sur, Compostela Valley, Davao del Norte, Davao Oriental, Bukidnon, Camiguin, Lanao del Norte, Misamis Occidental, Misamis Oriental, and Zamboanga de Norte, all in the Northern and Eastern Mindanao.
As of 10:30 a.m. yesterday, the LPA was spotted in the vicinity of Malaybalay City in Bukidnon.
PAGASA said the LPA is over Mindanao, but the cloudiness is concentrated over Southern Luzon, the Visayas, and Northern and Eastern Mindanao.
Due to the combined effects of the LPA and the tail-end of a cold front, scattered to widespread rains are expected over these areas until today.
As of yesterday, a one-hour recorded rainfall in Tacloban City (23.6 mms), Borongan in Eastern Samar (14 mms), and Catbalogan in Samar (30.6 mms) were considered heavy rainfall.
Likewise, the one-hour rainfall data in Camarines Sur, particularly in Camaligan (17 mms.), Ombao (13 mms), Buhi (12 mms), Bato (13 mms), and Ligao (25 mms) were all classified as heavy rainfall.
Heavy rains were also recorded in Catanduanes, Sorsogon, and Albay.
Meanwhile, light to moderate rains were noted in Southern Luzon.
PAGASA rainfall threshold (in mm/hour or mm) is classified as light if less than 2.5 mms, moderate if it is between 2.5, and 7.5 mms, and heavy if it is greater than 7.5 mms.
