A LOW pressure area is threatening to develop into a tropical depression by Monday night or Tuesday morning, the weather bureau said Monday.
If it becomes a tropical depression, it will be named “Agaton,” the first typhoon for 2018.
If it does not change its direction, it could make landfall in the Caraga Administrative Region.
The LPA brought a wet New Year’s Day in Bicol, Eastern Visayas, Caraga and Davao.
Forecaster Aldczar Aurelio said affected areas should brace for possible flash floods and landslides spawned by moderate to heavy rainfall.
Heavy rains and thunderstorms were expected in the Visayas and some parts of Mindanao due to the low pressure area over Surigao City, Surigao del Norte, the weather bureau said.
In its latest bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration said Visayas, Caraga, and Northern Mindanao would experience cloudy skies with scattered to widespread rains and thunderstorms brought by the trough of the LPA.
Pagasa said the Bicol region and the rest of Mindanao would experience cloudy skies with scattered rains and thunderstorms.
Meanwhile, the northeast monsoon would bring cloudy skies with scattered rains over Cagayan Valley, Cordillera Administrative Region, Aurora and Quezon.
Metro Manila and the rest of Luzon would have partly cloudy to cloudy skies with isolated rains.
As of 3 a.m., Pagasa said the LPA was spotted 545 kilometers east of Surigao City.
