The southwest monsoon or “habagat” that is being enhanced by two weather disturbances inside and outside the country’s area of responsibility is still expected to bring some rains over several areas in Luzon, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Wednesday, Aug. 4.
Weather specialist Benison Estareja said that a low pressure area (LPA) was located at 550 kilometers (km) northeast of Itbayat, Batanes, or inside the Philippine area of responsibility (PAR) at around 3 a.m.
“Based on the PAGASA’s latest analysis and LPA’s current track, the LPA will likely be outside the PAR tomorrow (Aug. 5) but there is still a chance that it will become a tropical depression while exiting the PAR,” Estareja said in the PAGASA’s daily weather bulletin.
“We will continue to monitor the LPA because even if it is already outside the PAR when it becomes a tropical cyclone near the southern islands of Japan, it is still possible for it to enhance the southwest monsoon,” he added.
Meanwhile, a tropical depression was spotted near Hong Kong. It was estimated at 735 km west of extreme northern Luzon as of 3 a.m.
“We expect this to come a little closer to the boundary of PAR but the chances of it entering our country are still low. Nonetheless, the LPA and the tropical depression are expected to slightly enhance the southwest monsoon in the next few days,” Estareja added.
PAGASA said that moderate to heavy monsoon rains may still be felt in Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Batanes, Babuyan Islands, Abra, Apayao, Benguet, Zambales, and Bataan.
Likewise, occasional light to moderate with at times heavy rains may prevail over Metro Manila, Tarlac, Pampanga, Bulacan, Nueva Ecija, Cavite, Batangas, Occidental Mindoro, northern Palawan including Calamian and Kalayaan Islands, Ifugao, Kalinga, Mountain Province, the rest of Cagayan, Isabela, Quirino, and Nueva Vizcaya.
The rest of the country will be partly cloudy to cloudy with isolated rain showers or thunderstorms.
Estareja said Metro Manila may have improved weather conditions by Friday and Saturday, Aug. 6-7, but there may still be some rain showers due to the slight effect of the southwest monsoon.
