MANILA -- Angat Dam, which supplies water to Metro Manila and Central Luzon, may hit critical level in 1 or 2 days, the state weather bureau said Thursday.
Regulators earlier said the allocation for Metro Manila's water supply may be reduced if the dam hits the 160-meter critical level.
Angat Dam has dipped to 160.73-meter mark as of 6 a.m., PAGASA weather forecaster Benison Estareja told ABS-CBN News.
With no rains expected from the habagat or southwest monsoon until the weekend, the dam's level may reach critical mark in 1 or 2 days, he said.
The NWRB last month slashed water allocation for agriculture, saying this would not affect food supply because farmers were already in the middle of the planting season.
The dam's declining water level, lack of rains due to El Niño, and high demand were blamed for a water supply shortage that brought misery to more than a million households in Metro Manila in March.
PAGASA on Friday declared the start of the rainy season.
However, PAGASA also said weak El Niño conditions which were felt in the tropical Pacific since the last quarter of 2018 is "likely to continue" until August.
