Easterlies, or warm air from the Pacific Ocean, are bringing partly overcast skies with scattered thunderstorms throughout the country, according to a forecast issued by the state meteorological service Wednesday morning.
Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) weather specialist Benison Estareja also said they are monitoring a cloud cluster outside the Philippine Area of Responsibility (PAR) that may develop into a low-pressure area (LPA) and become a storm.
He said it is a residual low or weakened weather system from a tropical depression.
“Kapag sinabi natin na remnant low, ito ay nagmula as a tropical depression then humina na. Wala nang appreciable na hangin para ma-consider pa as bagyo. But for now, ito ay cloud cluster sa atin at posibleng anytime ay may mabuo na circulation na mako-consider siya as low-pressure area,” he said.
It will enter PAR on Thursday, August 19, and possibly develop as a storm.
Based on the forecast track, the weather system can stay inside PAR from Thursday until the weekend moving in the west-northwest direction.
It is possible to traverse near Batanes and Babuyan islands over the weekend but is less likely to make landfall or directly affect the landmass of Luzon, Visayas, and Mindanao.
PAGASA did not raise any gale warnings over the seaboards of the country due to the monsoon break. The water condition is slight to moderate, but wave height is possible to reach 0.6 to 2.5 meters during thunderstorms.
