Answer:
IF Mother Nature will not produce the rain needed to irrigate farms and turn on power generators, the country can try cloud seeding.
But this process does not only entail spraying clouds with dry ice or silver iodides. In fact, not just any kind of cloud can be induced to produce rain.
And the help of weather experts is needed to ensure the success of a cloud-seeding operation.
Cloud seeding is the process of spreading dry ice or silver iodide aerosols on the upper clouds to simulate the precipitation process and induce rain.
According to Dr. Silvino Tejada, executive director of the Bureau of Soils and Water Management (BSWM), the success of cloud seeding operations, however, depends on the availability of cumulus clouds. These cotton-like, fluffy clouds are the “most efficient” in producing rain.

Cloud-seeding operations are made in coordination with the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) because wind direction should first be ascertained before the process is carried out.
On April 21, to prepare for the impending water shortage, the National Power Corp. (Napocor) called a meeting with officials of the BSWM (Bureau of Soil and Water Management) of the Department of Agriculture (DA), Metropolitan Waterworks and Sewerage System (MWSS) and Pagasa to discuss cloud-seeding operations to be conducted over Angat dam, as the water level of the reservoir had been dropping because of the summer heat.
