"Nagsimula na po ang panahon ng tag-ulan dito sa ating bansa. Na-satisfy na po 'yung criteria ng rainfall sa mga Type 1 climate station kung kaya't opisyal nang dineklara ng PAGASA [na] simula na ng tag-ulan sa ating bansa," said PAGASA senior weather specialist Chris Perez in a Facebook Live video on Friday morning.
(The rainy season has begun in our country. The rainfall criteria in Type 1 climate stations have been satisfied which is why PAGASA has officially declared that the rainy season has begun.)
In a statement, PAGASA Administrator Vicente Malano also confirmed the "widespread rainfall recorded in most PAGASA stations during the past few days."
Malano said the western part of the country, including Metro Manila, will continue to experience scattered to widespread rainshowers and thunderstorms in the coming days.
"However, such rain events may be followed by dry periods – also known as a monsoon break – that could last for several days to two weeks," he added.
PAGASA made the announcement as the country deals with the combined effects of Tropical Storm Domeng (Maliksi) and the southwest monsoon. Though Domeng will not make landfall, it is enhancing the southwest monsoon. Luzon and the Visayas are experiencing moderate to heavy rain.
So far, the Philippines has had 4 tropical cyclones this year – Agaton, Basyang, Caloy, and Domeng. The country is visited by an average of 20 tropical cyclones a year. (READ: LIST: PAGASA's names for tropical cyclones in 2018)
