MANILA – The Philippine weather bureau reported on Thursday that parts of Luzon can expect rain showers from two distinct weather systems.

Scattered rain showers and thunderstorms are forecasted for the provinces of Quezon, Rizal, Laguna, and Camarines Norte, attributed to a shear line.

Meanwhile, a northeasterly surface windflow will bring rain to Batanes, Cagayan, Isabela, Apayao, Kalinga, and Aurora.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) warned that moderate to heavy rains in these regions may lead to flash floods and landslides.

PAGASA forecaster Patrick del Mundo mentioned that the rest of the country should expect isolated rain due to localized thunderstorms, with no gale warning issued for any part of the country.

Moderate to strong winds and moderate to rough seas are expected in Northern and Central Luzon, while elsewhere, winds will be light to moderate, and seas will be slight to moderate.

PAGASA is currently monitoring three weather systems beyond the boundaries of the Philippine Area of Responsibility (PAR). In its 4 a.m. weather update on Sunday, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported the following:

  1. Typhoon Koinu, previously known as Jenny, is nearly stationary and positioned 725 km west of the extreme Northern Luzon. It boasts maximum sustained winds of 155 kph and gusts of up to 190 kph.
  2. Tropical Storm Bolaven (international name) is situated 3,045 km east of the Visayas, moving slowly westward with maximum sustained winds of 65 kph and gusts of 80 kph.
  3. An area of low pressure (LPA) was detected 1,845 km east of the Visayas as of 3 a.m. Sunday.

PAGASA clarified that these three weather systems currently do not have any direct impact on any part of the Philippines. The weather outlook for Metro Manila and the rest of the country includes partly cloudy to cloudy skies with isolated rain showers and thunderstorms, attributed to the southwest monsoon or “habagat” and localized thunderstorms.

Northern and Central Luzon, along with the western section of Southern Luzon, can expect light to moderate winds blowing from the southwest to southeast, with slight to moderate coastal waters. Meanwhile, the rest of the country will experience light to moderate winds heading northeast to northwest, also with slight to moderate sea conditions.

Temperature-wise, the range is expected to be between 24.6°C and 32.7°C.
