Thunderstorm Surprises Manila Residents; Hailstorm Reported in Quezon City


MANILA, PHILIPPINES – In the middle of a hot Tuesday afternoon, a sudden downpour caused by a thunderstorm surprised residents in Metro Manila while other areas experienced hailstorms.

The downpour that lasted for less than two hours immediately triggered flooding in some parts of the metropolis.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) earlier issued a thunderstorm advisory in Metro Manila and warned that heavy rains, strong winds and possible flash floods may occur.

The heavy rains followed days of sizzling temperatures and Pagasa said warmer days were expected with the end of the northeast monsoon and the shift of wind direction from northeasterly to easterly.

“With this development, associated weather conditions include increasing number of warm days and generally good weather in most areas of the Philippines partly due to the dominance of the ridge of High Pressure Area and the easterlies,” Pagasa said.

While the sudden downpour surprised Metro Manila residents, people in nearby areas were even more surprised to see tidbits of snow falling from the sky.

The hailstorm was reported in some parts of Quezon City, with residents taking photos and videos of snow as a big as marbles.

Experts said hail forms in strong thunderstorm clouds, particularly those with intense updrafts, high liquid water content, great vertical extent, large water droplets, and where a good portion of the cloud layer is below freezing.

Like other precipitation in cumulonimbus clouds hail begins as water droplets. As the droplets rise and the temperature goes below freezing, they become supercooled water and will freeze on contact with condensation nuclei. –
