A hailstorm occurred over areas of Metro Manila and the province of Nueva Ecija at about 5:30 p.m. on Thursday, causing a rain of ice pellets of about half-an-inch in diameter.
The phenomenon, which lasted for about 10-15 minutes, was recorded at Batasan Hills, Commonwealth Avenue and Filinvest in Quezon City, and in Peñaranda, Nueva Ecija.
The Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) assured the public not to be worried about hailstones which are formed through a combination of warm, moist and stormy weather conditions.
As thunderstorm updrafts become strong enough to carry water droplets that are already above the freezing level, hailstones are formed. These ice pellets eventually become too heavy for the updrafts to carry, causing it to fall to the ground.
Pagasa records have shown there had been previous incidents of hailstorms in Quezon City, particularly on Visayas Avenue.
