Based on data from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), water elevation in Angat Dam on Saturday was measured at 161.35 meters above sea level (masl).

This was higher by at least 1.19 meters from the previous 160.16 masl recorded in the watershed on Friday morning and from the 158.27 masl on Thursday.

However, the current level of water in Angat Dam was still 18.65 meters below the 180-meter minimum operating water level needed to resume the irrigation supply allocation to nearby provinces.

The Angat Dam, located in Norzagaray, Bulacan, is the major water source of households in Metro Manila and neighboring provinces.

Aside from Angat Dam, water level in other major watersheds also increased including La Mesa Dam at 73.21 masl on Saturday from 73.09 masl on Friday; Ambuklao Dam at 743.68 masl from 743.11 masl; Binga Dam at 568.79 masl from 568.34 masl; San Roque Dam at 230.77 masl from 230.74 masl; and Pantabangan Dam at 189.18 masl from 189.02 masl.

In an earlier statement, the National Water Resources Board (NWRB) said that monsoon rains and expected tropical cyclones this month are expected to replenish the water supply in Angat Dam.

Meanwhile, as Tropical Depression “Goring” weakened into a low pressure area (LPA) before it exited the country on Friday night, southwest monsoon or “habagat” will continue to bring rains in the country this weekend.

PAGASA weather specialist Meno Mendoza said monsoon rains will prevail over most parts of Luzon particularly in Batanes, Calayan, Babuyan Group of Islands, Ilocos Region, Cordillera Administrative Region, Zambales and Bataan.

The southwest monsoon will also bring partly cloudy skies with isolated rainshowers and thunderstorms in Metro Manila and the rest of Luzon.

The rest of the country will experience partly cloudy to cloudy skies with isolated rainshowers due to localized thunderstorms.

A gale warning was also raised on the coasts of Batanes, Calayan, Babuyan, northern coast of Cagayan, and Ilocos Norte. Coastal waters on these seaboards will be strong and can reach a wave height of up to 4.5 meters.

PAGASA has warned fishermen and others with small vessels not to venture on coastal waters of provinces where a gale warning was raised.
