PAGASA weather specialist Veronica Torres said that the shear line will bring rains in extreme Northern Luzon while easterlies or warm wind in the Pacific Ocean will affect the rest of the country.
“We should expect cloudy and scattered rains in Batanes and Babuyan Island because of the shear line,” Torres said.
Torres added that Metro Manila and the rest of the country will experience localized thunderstorms in the afternoon until evening.
“The rains that we are experiencing are possible indication that we are shifting to the rainy season,” she said.
Meanwhile, the water level of Angat Dam further dropped by .25 meters after it reached 180.95 meters compared to its previous level of 181.20 meters. It was 31.05 meters below its normal high water level of 212 meters.
It is only .95 meters above its minimum operating level of 180 meters.
Angat Dam supplies more than 90 percent of Metro Manila’s potable water needs and provides for the irrigation needs of 25,000 hectares of farmlands in Bulacan and Pampanga.
The National Water Resources Board decreased the water allocation of Metro Manila by one cubic per second on March 16 or 49 cms from the previous 50 cms amid the continued drop in elevation of Angat Dam.
The Metropolitan Waterworks and Sewerage System gave assurance that there will be no water interruption despite the cut in water allocation for domestic use.
