PAGASA declares start of rainy season, warns of La Niña risks

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) declared the start of the rainy season on Wednesday, May 29.

Significant rainfall has been observed recently over western sections of Luzon and Visayas due to scattered rain showers, frequent thunderstorms, Typhoon Aghon's passage, and the Southwest Monsoon (Habagat).

PAGASA noted that there is a 60% chance of La Niña occurring between June and August, increasing the likelihood of above-normal rainfall conditions in some areas by July-August-September.

The weather bureau warned the public and agencies to take precautionary measures against flood risks and rain-induced landslides during this period.

For June to November, PAGASA expects 0 to 13 tropical cyclones to enter or develop inside the Philippine Area of Responsibility.

Typhoon Aghon was the first typhoon to affect the Philippines in 7 months and has since left the Philippine Area of Responsibility.
