As the frequency of localized thunderstorms increases due to the approaching rainy season, hail occurrences are also becoming more common, a Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) expert said on Thursday, May 16.

In a televised interview, PAGASA-Climate Monitoring and Prediction Section (CLIMPS) Officer-in-Charge Ana Liza Solis said localized thunderstorms are a precursor to the rainy season.

Solis explained that hail can occur during a severe thunderstorm when tiny ice fragments condense into raindrops.

"Because of our hot weather, severe thunderstorms can form, leading to the development of large, intense clouds. As these clouds move over our area with their low bases, they can release small pieces of ice, known as hail, onto the ground. Due to the heat, the hail doesn't immediately melt as it falls to the earth,” she explained in Filipino.

PAGASA said severe thunderstorms usually occur in the afternoon or evening and last up to two hours. 

Aside from hail, they are often accompanied by sudden heavy rains, lightning, thunder, and gusts of wind.

PAGASA also warned that severe thunderstorms may cause flash floods or landslides.
