The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has officially declared the onset of the rainy season on Friday after tropical depression “Butchoy” and the southwest monsoon brought significant amounts of rain over the western section of Luzon and Visayas in the last five days.

The state weather bureau said in a press statement that the amount of rain in the past five days has indicated the shift to the wet season..

“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,” PAGASA stated.

However, PAGASA added that rain occurrence might be followed by dry periods or monsoon breaks that could last for several days up to two weeks.

The southwest monsoon affects the country during the late month of June until October.

“PAGASA will continue to closely monitor the situation and updates/advisories shall be issued as appropriate. The public and all concerned agencies are advised to take precautionary measures against the impacts of the rainy season,” it added.

Meanwhile, as of 3 p.m. Saturday, Butchoy is already outside the Philippine Area of Responsibility (PAR). Its location is 735 kilometers west of northern Luzon with maximum sustained winds of 75 kilometers per hour near the center.

Its gustiness is 90 kilometers per hour and moving north northwest at 25 kilometers per hour.
