Hello how may I help you? I am trying to find out something about clouds. What would you like to know? Well, I was wondering what the biggest cloud that was ever recorded was? Are you wanting to know the tallest, the widest, or the heaviest? I don't really know. When you look at the sky, which cloud looked the biggest, and what was it's measurement? What it bright or dark category? Maybe the dark category?? Okay, give me one moment There is a cloud that was 5,014 ft long and it was almost black in color, it was very rainy could have destructed houses and builings. Is there anything else? That sounds like one very scary looking cloud. No, that's it for today. Thanks. You are welcome, have a great day!
