A frontal system is expected to bring cloudy skies with scattered rain and isolated thunderstorms over Batanes and the Babuyan Islands, PAGASA announced Thursday.
In its 24-hour forecast, the weather agency warned against possible flash floods or landslides during severe thunderstorms.
Meanwhile, Easterlies, warm winds from the Pacific Ocean, and localized thunderstorms may bring partly cloudy to cloudy skies with isolated rainshowers over Metro Manila and the rest of the country.
Flash floods and landslides are also possible, PAGASA warned.
The temperature at the Science Garden, Quezon City dropped to 27.3°C at 6 a.m. and peaked at 35.4°C at 1:30 p.m.
GMA's resident meteorologist Nathaniel "Mang Tani" Cruz, meanwhile, warned of hazards associated with thunderstorms during thunderstorm season.
Residents should expect strong winds and heavy rain which may cause flooding, according to Cruz.
He also advised the public to be cautious as they may be hit by lightning.
Severe thunderstorms may also cause hailstorms, or a rain of ice, and tornadoes should the thunderstorm be situated over the sea. — Joahna Lei Casilao/BM, GMA News
