MANILA – The low-pressure area (LPA) may become a tropical depression on Thursday and would be named "Butchoy", the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.

The LPA was last tracked 50 kilometers east northeast of Virac, Catanduanes or 245 kilometers north northwest of Borongan City, Eastern Samar.

PAGASA weather specialist Raymond Ordinario said the LPA may become a tropical depression any time on Thursday.

"The LPA is affecting Bicol Region and Eastern Visayas. It may traverse Central and Northern Luzon by the weekend," he said.

The LPA and the southwesterly wind flow affecting Palawan, Western Visayas, and Mindanao are currently causing scattered to widespread rains and thunderstorms over Metro Manila, Visayas, Central Luzon, Bicol Region, Calabarzon, Mimaropa, and Isabela.

The two weather systems also cause scattered rains and thunderstorms over Mindanao and the rest of Cagayan Valley.

The rest of Luzon will experience isolated rain showers due to localized thunderstorms, according to PAGASA.

Moderate winds with moderate coastal waters will prevail over Bicol Region and the Visayas.

Elsewhere, winds will be light to moderate with slight to moderate seas. (PNA)
