The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the southwest monsoon or "habagat" may continue to bring cloudy skies and scattered rain showers over some parts of northern, Central, and Southern Luzon, including Metro Manila in the next 24 hours.
In the weather bulletin on Friday afternoon, June 25, PAGASA said monsoon rains may affect Metro Manila, Cavite, Laguna, Batangas, Rizal, Quezon, Aurora, Bulacan, Nueva Ecija, Tarlac, Pampanga, Bataan, Zambales, Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Oriental Mindoro, Occidental Mindoro, Batanes, and Babuyan Islands.
PAGASA warned against possible flash floods or landslides as rains may become moderate to at times heavy.
Meanwhile, the rest of the country will have partly cloudy to cloudy skies with isolated rain showers due to habagat and localized thunderstorms.
PAGASA also advised the public to stay vigilant against flash floods or landslides that may occur during severe thunderstorms.
Meanwhile, the tropical cyclone with international name "Champi," which remains outside the Philippine area of responsibility (PAR) has intensified into a typhoon.
As of 3 p.m., Champi was estimated at 1,770 kilometers east of extreme northern Luzon with maximum sustained winds of 120 kilometers per hour (kph) near the center and gustiness of up to 150 kph. It was moving north-northwestward at 20 kph.
PAGASA said the typhoon has a slim chance of entering the PAR and may not have a direct effect over the country in the next few days.
