The effects of the southwest monsoon or “habagat” have temporarily weakened but some light rains may still persist over western Luzon, according to the State weather bureau yesterday.
The Philippine Atmospheric, Geophysical, and Astronomical Services Administration said light to moderate rains and isolated thunderstorms will still prevail over Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Abra, Benguet, Ifugao, Kalinga, Mountain Province, Apayao, and Zambales.
An intertropical convergence zone, which is a breeding ground for potential low pressure area and tropical cyclone, will prevail over Mindanao.
PAGASA said the ITCZ will bring cloudy skies with scattered rain showers thunderstorms over Compostela Valley, Davao del Norte, Davao Oriental, and Davao del Sur.
Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers due to localized thunderstorms.
PAGASA warned that rains, especially during severe thunderstorms, could trigger possible flash floods or landslides over low-lying and mountainous areas in the entire archipelago.
Meanwhile, the water level at Angat Dam continues to decline due to lack of rain over Bulacan’s watershed area.
As of yesterday, Angat Dam’s water level was at 162.82 meters, further down from last Saturday’s 163.12 meters.
PAGASA earlier said that the Angat Dam could reach its 160-meter critical level for domestic water supply in a few days, should there be no rains and the allocation for domestic supply remains the same. (Ellalyn V. Ruiz)
