MANILA, Jan. 29 (PNA) – Metro Manila's main water source Angat Dam in Norzagaray, Bulacan is in for drier days ahead with the government weather agency projecting rainfall there to slip from near- to below-normal levels in the next four months, raising urgency for more water conservation.
In its latest forecast, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) noted near-normal rainfall of almost 55 millimeters can be expected there this February.
The agency also expects near-normal rainfall in the dam by March but at a lesser 41.3 millimeters.
PAGASA forecasts rainfall in Angat Dam to further ease afterwards, reaching this April a below-normal level of about 22.8 millimeters only.
Below-normal rainfall is still likely in that dam this May although at a higher 235 millimeters, noted PAGASA.
Rainfall there is forecast to further increase to the already above-normal level of 541.7 millimeters beginning June, PAGASA continued.
According to PAGASA, several weather systems may affect the country during the February-July period.
Those weather systems are the tail-end of a cold front, the easterlies, ridge of high-pressure areas, northeast monsoon, southeast monsoon, inter-tropical convergence zone, low-pressure areas, monsoon trough and tropical cyclones. said PAGASA.
The agency expects the termination of the northeast monsoon this March.
Between five and eight tropical cyclones are likely in the country during the February-July 2015 period, PAGASA added. (PNA)
