MAKATI CITY – Ice instead of just plain old rain fell down the streets of Makati on Wednesday, September 17.
This rare meteorological event however cannot be considered a hailstorm said weather bureau PAGASA forecaster Jun Galang. The ice pellets were due to cumulonimbus clouds, a type of thunderstorm cloud that formed around Makati and nearby areas.
“It’s only normal when there are thunderstorm clouds. It is possible that from the clouds, the ice pellets are originally big in size, but they get smaller as they get nearer to the ground,” Galang told Rappler.
PAGASA initially reported of possible thunderstorms in Metro Manila, particularly Manila, Pasay, Taguig, Parañaque, Baclaran, and Las Piñas and warned that heavy rains should be expected. Makati clearly got a different end of the bargain.
Netizens took notice of the rare (for the Philippines) meteorological event:
Department of Atmospheric and Oceanic Sciences at UW-Madison explained what hails are:
Hail is precipitation in the form of large balls or lumps of ice. There was a storm that produced hail early last week. Hailstones begin as small ice particles that grow primarily by accretion; to grow large, they require abundant water droplets. As the hailstone moves up and down through a storm, it collides with water droplets, growing larger with each collision. Hailstones can be as large as oranges and grapefruits.
