State weather bureau PAGASA on Friday said it is monitoring the possible development of a "weak La Niña" in the country.
"We're not ruling out the possibility that by the end of the year ay magkaroon ng weak La Niña episode sa central equatorial pacific," PAGASA weather forecaster Chris Perez said in an interview on radio DZMM.
The weak La Niña is expected to bring "near normal to above normal rainfall" over the holiday season, Perez said.
Despite the possibility of a weak La Niña, high temperature may still be experienced in low lying areas such as Center Luzon. Areas in mountainous regions, however, may have cooler temperatures, he said.
Perez said the isolated rainshowers experienced in Manila and other parts of the country are not effects of the possible La Niña, but are brought by tail end of a cold front.
