The hailstorm that thrashed several parts of Kuala Lumpur and Selangor on Friday was a normal phenomenon.
Science, Technology and Innovation Minister Madius Tangau said in a statement yesterday, that hail would occur when there was a severe thunderstorm and when the cumulonimbi clouds (which is the main source for the formation of a thunderstorm) reached a height of 40,000 feet.
“When the temperature goes below freezing point, the rain drops become ice lumps sized 1.5cm, about the size of a marble,” he said.
Hailstorms would normally happen anytime in Malaysia and in areas that lie directly beneath cumulonimbi clouds, he said.
Heavy thunderstorms and hail caused havoc in the Klang Valley two days ago, bringing traffic to a gridlock, uprooting trees, disrupting LRT and ERL services as well as destroying buildings.
