The low pressure area (LPA) northeast of Romblon dissipated at 8 am on Wednesday, January 20, but another LPA developed east of Southern Luzon at the same time, according to the state weather bureau.

In an advisory issued 11 am on Wednesday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said the new LPA is now 250 kilometers east of Virac, Catanduanes.

So far, it is “less likely to develop into a tropical depression in the next 24 hours.” (READ: FAST FACTS: Tropical cyclones, rainfall advisories)

But the LPA and the tail-end of a frontal system are both bringing rain to several areas in Luzon on Wednesday. The tail-end of a frontal system, in particular, is affecting the eastern part of Central Luzon.

Here is PAGASA’s rainfall forecast for the next 24 hours:

Moderate to heavy rain, with at times intense rain

• Isabela
• Quirino
• Aurora
• eastern part of Cagayan

Light to moderate rain, with at times heavy rain

• rest of Cagayan Valley
• Cordillera Administrative Region
• Calabarzon
• Nueva Ecija

In addition, the National Capital Region-PAGASA Regional Services Division said light to moderate rain was being experienced in parts of Metro Manila.

PAGASA warned areas affected by the LPA and the tail-end of a frontal system to watch out for possible floods and landslides.
