WET weather is expected to prevail in the country for the next three months as state weather forecasters declared on Tuesday the onset of the rainy season.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said in a statement that the country has been experiencing frequent rainshowers and thunderstorms that signal the start of the rainy season.

“It is expected that in the coming days, moderate to heavy rains will be experienced over the most parts of Western Luzon and Western Visayas due to the low pressure area (LPA) and the southwest monsoon," Pagasa acting administrator Vicente Malano said.

Monsoon breaks or period of no rain for a few weeks are also expected during the period, Pagasa said.

The state weather bureau announced earlier that the rainy season could start by mid-June. Last year, the wet season came in at June 10.

Explaining the delay, Pagasa weather specialist Shelly Ignacio said a high pressure area in the Pacific Ocean had blocked the entry of the southwest monsoon. The country is also experiencing a dry spell caused by the El Niño phenomenon.

Around 11 storms are expected to enter the Philippines in the second half of the year, including two or three in June alone, according to the weather bureau. (Jan Keanu Plantilla, UST intern/Sunnex)
