On August 28, according to storm news, the latest low pressure from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), 2 low pressure areas appeared inside and outside the Philippine Area of Responsibility (PAR).
One of the 2 low pressure areas is likely to strengthen into a storm in the next 24 hours, while the remaining system is expected to enter PAR by the weekend and may develop into a tropical depression.
As of 3:00 PM on August 28, the first low pressure area is located about 560km northeast of Itbayat Island, Batanes province.
PAGASA assesses that this system still has a moderate possibility of strengthening into a storm in the next 24 hours. However, the low pressure area is forecast to move out of PAR in the near future.
Therefore, despite its development potential, this system is forecast not to have a direct impact on the Philippines.
The second low pressure area formed in the afternoon of August 28, located very close to PAR.
According to PAGASA, by 2 pm on the same day, the system was located about 1,460km east of central Luzon.
This low pressure area is forecast to enter PAR by the end of the week. If it develops into a tropical depression, the system will be named Pilandok by PAGASA.
Forecasts show that the system may move towards the Ryukyu Islands of Japan or Taiwan (China) early next week. Therefore, the low pressure area is not forecast to make landfall or directly affect the Philippines.
However, the system could strengthen the southwest monsoon (Habagat), leading to heavy rain in western Luzon over the weekend.
PAGASA forecasts rainfall of 100-200mm in Ilocos, Abra, Benguet, Zambales, Bataan, Tarlac and Occidental Mindoro.
Meanwhile, Metro Manila, the rest of Cordillera region, Nueva Vizcaya, most of Central Luzon, Calabarzon and Oriental Mindoro may record rainfall of 50-100 mm.
Heavy rain is warned to cause widespread flooding and landslides, especially in areas prone to natural disasters.
PAGASA recommends that people closely monitor weather reports and local government instructions. The agency also noted that forecasts may continue to change as low pressure areas develop and move.
