MANILA – Two weather disturbances – a low-pressure area (LPA) and a tropical storm (TS) – are unlikely to enter the Philippine Area of Responsibility (PAR).

In its 5 a.m. weather bulletin on Wednesday, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the LPA was last tracked at 2,090 km. east-northeast of extreme northern Luzon.

"It has a slim chance of developing into a tropical cyclone, and it could possibly recurve and not enter PAR," weather forecaster Grace Castañeda said.

Castañeda added that the LPA has no direct effect on the country while the TS, with the international name “Mulan”, has a slim chance of entering PAR.

"However, it enhances the southwest monsoon, which will bring rains over parts of Luzon," Castañeda said.

On Wednesday, the southwest monsoon is forecast to cause scattered rain showers and thunderstorms over the provinces of Zambales and Bataan and the Kalayaan Islands, as well as the Ilocos region.

Flash floods or landslides are likely during moderate to at times heavy rains.

Metro Manila and the rest of the country will have isolated rain showers caused by localized thunderstorms.

Moderate to strong winds and moderate to rough seas will prevail over the western section of Luzon.

Elsewhere, winds will be light to moderate with slight to moderate seas. (PNA)
