The low-pressure area (LPA) near Southern Luzon may develop into a tropical depression within 48 hours, said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Thursday, July 13.
PAGASA's next tropical cyclone name will be "Dodong."
In its 11 a.m. weather advisory, PAGASA said the LPA was last spotted 160 kilometers east-northeast of Infanta, Quezon.
It warned that the combined effects of the LPA and the enhanced southwest monsoon, or “habagat,” may bring “significant” rains over the next three days.
The following areas may experience heavy rains until July 15.
-
July 13, Thursday — Metro Manila, Cavite, Laguna, Batangas, Rizal, Quezon, Aurora, Isabela, Cagayan
-
July 14, Friday — Cagayan, Isabela, Quirino, Nueva Vizcaya, Batanes, Abra, Apayao, Benguet, Ifugao, Kalinga, Mountain Province, Zambales, Bataan, Occidental Mindoro, Aklan, Antique, Capiz, Guimaras, Iloilo, Negros Occidental, northern Palawan
-
July 15, Saturday — Zambales, Bataan, Occidental Mindoro, Aklan, Antique, Capiz, Guimaras, Iloilo, Negros Occidental, Palawan
Meanwhile, PAGASA said intense rains may affect Ilocos Norte, Ilocos Sur, La Union, and Pangasinan from Friday to Saturday.
“Under these conditions, flooding and rain-induced landslides are possible, especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps and in localities that have received considerable amounts of rainfall over the past several days,” it said.
