IDINEKLARA na ng Philippine Atmospheric Geophysical and Astronomical Services Administration ang opisyal na pagsisimula ng tag-ulan kahapon.
Ang pag-ulan umano sa nakaraang limang araw kasama ang ulan na dala ng bagyong Butchoy ang kumompleto sa mga kriteria na kailangan sa pagdedeklara ng pagsisimula ng tag-ulan sa bansa.
“The occurrence of scattered thunderstorms, Tropical Depression “BUTCHOY” and the Southwest Monsoon (Habagat) during the last five days have brought a significant amount of rains over the western sections of Luzon and Visayas. This satisfies the criteria of the start of the rainy season in the areas affected by Habagat which will continue to experience scattered to widespread rains and thunderstorms in the coming days.”
“However, such rain events may be followed by dry periods (monsoon break) that could last for several days to two weeks.”
Ipinayo ng PAGASA na magantabay sa mga update at advisory na ipalalabas nito.
