Interesting fact: A typical thunderstorm cloud can contain millions of kilograms of water in the form of droplets and ice particles.
The answer: An average thunderstorm cloud weighs about 500,000 kilograms (1.1 million pounds), mostly from water droplets and ice suspended in the air.
Thunderstorms form when moist air rises and cools, condensing water vapor into droplets and ice. The weight of a thunderstorm cloud is the total mass of these suspended water particles. Despite their massive weight, clouds float because the air below is denser. The water eventually falls as rain, hail, or snow.
