THE Climate Change Commission (CCC) on Monday warned the public to prepare for increasing heat waves in the coming months that could cause drought and water shortages.In a statement, CCC Commissioner Albert de la Cruz Sr. said dry spells will occur despite the heavy rains drenching parts of the country.Citing data from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa), de la Cruz said the weather bureau has declared the occurrence of El Niño in the tropical Pacific after the Oceanic Niño Index recorded 0.5 C in April, May and June.Moreover, Apayao, Cagayan and Kalinga are already experiencing drought based on the 60 percent reduction in the expected rainfall in these areas.Dry conditions were also experienced in Isabela and Tarlac.De la Cruz also cautioned the public against prolonged rainfall and eventual flash floods that could disrupt daily routines and affect the prices of prime commodities.'Last week, heavy rain triggered floods and caused traffic congestion in several parts of Metro Manila, leaving thousands of commuters stranded. Intense heat caused by El Niño can also result in increased rainfall,' he said. 'There will be rain in Metro Manila and other areas due to the phenomenon's weakened state even as rainfall patterns likewise depend on our geographical location.' During an El Niño episode, warmer ocean temperatures lead to changes in atmospheric circulation patterns that enhance the development of low-pressure systems and the formation of atmospheric moisture, resulting in more precipitation, de la Cruz said.
