PAGASA: Expect frequent thunderstorms
MANILA - The state weather bureau on Monday warned of frequent thunderstorms in the coming days, especially during the first week of classes.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said rains will most likely be experienced in the afternoon or in the evening, as the summer season enters the transition period.
PAGASA clarified the rainy season hasn't started.
Weather forecaster Fernando Cada said PAGASA may only declare the onset of the rainy season once the southwest monsoon (habagat) starts to blow and 5 weather monitoring stations in the western part of the country record a total of at least 25 millimeters of rainfall.
Parts of Metro Manila, particularly areas in Quezon City and Manila City, were flooded as heavy rain fell on Monday.
Last year, PAGASA declared the onset of the rainy season during the second week of June.
Meanwhile, Cada said the effects of the foreseen El Niño will be felt during the last quarter of the year until the first part of 2015, especially because it overlaps with the country’s rainy season.
PAGASA earlier said the onset of the El Nino phenomenon later this year could bring a dry spell in Luzon as well as strong tropical storms.
"Westerly winds will get stronger because of the effect of El Niño and typhoons normally tend to shift northwards, towards Northern Luzon," said PAGASA Deputy Director for Operations and Services Landrico Dalida.
In its 5 p.m. 24-hour weather forecast, PAGASA said the whole country will experience partly cloudy skies with isolated rainshowers or thunderstorms mostly in the afternoon or evening.
