Inanunsyo ng Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) nitong Huwebes, Hunyo 4, na opisyal nang nagsisimula ang tag-ulan sa bansa.
Ayon sa PAGASA, ito raw ay nakabatay sa obserbasyon at pag-aanalisang isinagawa nila sa gitna ng mga pag-ulang may kaugnayan sa Southwest Monsoon o Habagat.
“Based on the weather observations and analyses, occasional to frequent rains associated with the Southwest Monsoon (Habagat) have been observed over the past five days,” saad ng PAGASA.
Anila, “This signifies the onset of the rainy season across the western sections of Luzon and the Visayas.”
Nagbigay din ng paglilinaw ang ahensya kaugnay sa “monsoon breaks” at “El Niño” sa gitna ng naturang panahon.
“However, periods of reduced rainfall, commonly referred to as monsoon breaks, may occur and last for several days or weeks,” anang ahensya.
“Moreover, with the looming El Niño, enhanced Habagat rainfall over the western sections of Luzon and Visayas is highly likely during the season,” dagdag pa nila.
Pagtitiyak ng PAGASA, patuloy ang pagbabantay nila sa lagay ng panahon sa buong Pilipinas.
“PAGASA will continue to monitor the weather and climate situation in the country. The public and all concerned agencies are advised to take precautionary measures against the adverse impacts of the rainy season, Habagat, and other climate and weather events,” pagtatapos ng PAGASA.
