The low-pressure area (LPA) east of Luzon dissipated at around 8 a.m. on Wednesday, Aug. 27, said the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
The weather disturbance had been monitored last week but weakened before it could develop into a tropical cyclone.
With its dissipation, weather conditions in affected areas are expected to gradually improve.
Meanwhile, PAGASA continues to monitor another LPA located west of Luzon.
As of 8 a.m., Wednesday, the weather system was spotted 250 kilometers west of Dagupan City, Pangasinan.
It has a “medium” chance of developing into a tropical depression within the next 24 hours, but may not directly affect any parts of the country.
PAGASA said the LPA may exit the Philippine Area of Responsibility (PAR) by Wednesday evening or Thursday morning, Aug. 28.
Weather conditions across most parts of the country are expected to improve starting Thursday.
However, the southwest monsoon (habagat) may still bring heavy rainfall over some areas, particularly in the western sections of Mimaropa and Western Visayas.
From Wednesday noon to Thursday noon, Aug. 28, moderate to heavy rainfall (50-100 mm) is expected over Palawan, Occidental Mindoro, and Antique.
From Thursday noon to Friday noon, Aug. 29, rains may persist in Occidental Mindoro.
PAGASA advised the public to remain alert for possible flooding and landslides, especially in areas affected by the habagat.
