CALUMPIT, Bulacan – Despite rains brought about by the southwest monsoon, the water level of Angat Dam dropped to 161.34 meters on Sunday.

Vice Governor Wilhelmino M. Sy-Alvarado said that with the rains, the water elevation of Angat Dam should be more than 200 meters by this time.

Citing Provincial Disaster Risk Reduction and Management Office headed by Liz Mungcal, Alvarado said that from 161.69 water level last Friday and 161.45 last Saturday, the Angat Dam’s water level dropped to 161.34 meters as of 8 a.m. on Sunday.

He said, although it’s above the 160-meter critical level, it is still way below the 180 meters of the dam’s minimum operating level and in the high water level of 210.

The water level of Ipo dam last Sunday was 99.50 meters, while Bustos dam was 14.80 meters. Their normal water levels are 100.00 meters and 17.00 meters, respectively.

Humid days ahead

Warm and humid mornings with chances of rain showers will prevail over the entire country in the next two to three days due to the persistence of an anti-cyclone weather system.

According to Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) weather specialist Gener Quitlong, the weather bureau does not see the formation or entry of a low-pressure area or tropical cyclone inside the country’s area of responsibility until mid-week.

The ridge of a high-pressure area, an anti-cyclone weather system, will bring warm weather apart from isolated rain showers throughout the country, he said.

However, PAGASA advised the public that rains, especially during severe thunderstorms, could trigger possible flash floods or landslides over low-lying and mountainous areas.

Due to the lack of rain, Angat Dam’s water level further declined on Sunday.

Based on the PAGASA’s monitoring, the Angat Dam’s level was down to 161.22 meters on Sunday morning, from 161.45 meters last Saturday.

It was above the 160-meter critical level, but still way below Angat Dam’s 180-meter minimum operating level and 210-meter normal high water level.

The National Water Resources Board (NWRD) is expecting the water suppy to normalize during the peak of southwest monsoon or habagat season between

July and September but the public is still encouraged to continue conserving water to help in the Angat reservoir’s water level recovery.

This month, two to three cyclones usually enter or form inside the country’s area of responsibility, which either move west or northwest of Luzon, based on the PAGASA’s historical record.

PAGASA said the weak El Niño episode, which brought way below normal rainfall over most parts of the country will likely prevail through August, and has a chance to continue until the end of 2019.
