2 LPAs may merge, develop into tropical cyclone — PAGASA

Two low-pressure areas (LPAs) inside the Philippine Area of Responsibility (PAR) may merge and intensify into a tropical cyclone, which could enhance the southwest monsoon (habagat) and bring torrential rains over parts of the country in the coming days, said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) on Monday, July 21.
As of 3 p.m., PAGASA weather specialist Veronica Torres said one LPA was spotted 1,220 kilometers east of southeastern Luzon, while the other was located 405 kilometers east of Calayan, Cagayan.
Both weather systems have a “medium chance” of developing into a tropical depression within 24 hours and are expected to move northwestward.
Torres added that there is a possibility the two LPAs could merge into a single weather system.
Should either LPA strengthen into a tropical cyclone while still within the PAR, it will be named “Dante.”
Although the likelihood of landfall remains low for now, Torres warned that any intensification could further enhance the southwest monsoon, which is already expected to bring significant rainfall.
From Monday afternoon, July 21, to Tuesday afternoon, July 22, the habagat is expected to bring intense to torrential rainfall (100 to 200 millimeters) over Metro Manila, Zambales, Bataan, Pampanga, Bulacan, Cavite, Batangas, and Rizal.
Meanwhile, moderate to heavy rains (50 to 100 millimeters) may affect Pangasinan, Tarlac, Laguna, Quezon, and Occidental Mindoro.
From Tuesday afternoon to Wednesday afternoon, July 23, intense to torrential rains may persist in Metro Manila, Zambales, Bataan, Pampanga, Bulacan, Cavite, Batangas, Laguna, Rizal, and Occidental Mindoro.
Moderate to heavy rainfall is expected to continue in Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Tarlac, Quezon, Oriental Mindoro, Marinduque, Romblon, Masbate, Sorsogon, Albay, Camarines Sur, Catanduanes, Antique, Aklan, Capiz, Iloilo, Guimaras, and Negros Occidental.
By Wednesday afternoon through Thursday afternoon, July 24, heavier rains will likely shift northward.
Intense to torrential rainfall may affect Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Abra, Benguet, Zambales, Bataan, and Occidental Mindoro.
Metro Manila, Apayao, Tarlac, Pampanga, Bulacan, Cavite, Batangas, Rizal, Laguna, Quezon, Oriental Mindoro, Marinduque, Romblon, Masbate, Sorsogon, Albay, Camarines Sur, Aklan, and Antique may still experience moderate to heavy rainfall.
PAGASA advised residents in flood- and landslide-prone areas, particularly those that have already received significant rainfall, to remain vigilant.
