Scattered rain showers and thunderstorms due to the enhanced southwest monsoon or "habagat" will prevail over Ilocos region, Zambales, Benguet, Batanes, and Babuyan Islands in the next 24 hours, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Friday afternoon, Aug. 6.
PAGASA warned against possible flash floods or landslides during moderate to at times heavy rains.
Weather specialist Ariel Rojas said two tropical storms named "Lupit" and "Mirinae" (formerly Gorio) are outside the Philippine area of responsibility (PAR) but are helping enhance the southwest monsoon.
Lupit and Mirinae were located 525 kilometers (km) north-northwest of Itbayat, Batanes, and 1,390 km northeast of extreme northern Luzon, respectively, around 3 p.m.
Rojas said Lupit may enter the PAR but may only skirt the area's northwestern quadrant.
"So hindi rin siya magtatagal. Pwedeng pagkapasok ay lalabas agad (So it won't last long inside the PAR. It may enter then immediately leave afterward)," he said in the PAGASA's live weather forecast.
Meanwhile, Mirinae has a slim chance of entering PAR as it moves towards the southern part of Japan, he noted.
Rojas said both weather disturbances have no direct effect on the Philippines but will continue to pull the southwest monsoon onto the country that could bring rain showers over some parts of Luzon.
Meanwhile, Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms.
PAGASA also advised the public to remain vigilant against flash floods or landslides that may occur during severe thunderstorms.
