Mammatus clouds are pouch-like protrusions hanging from the undersides of clouds, usually thunderstorm anvil clouds but other types of clouds as well. Composed primarily of ice, these cloud pouches can extend hundreds of miles in any direction, remaining visible in your sky for perhaps 10 or 15 minutes at a time.
People associate them with severe weather, and it’s true they can appear around, before or after a storm. Contrary to myth, they don’t continue extending downward to form tornados, but they are interesting in part because they’re formed by sinking air. Most clouds are formed by rising air. Mammatus clouds can appear ominous. But, in a way that’s so common in nature, their dangerous aspect goes hand in hand with a magnificent beauty.

He wrote: “I took an early morning walk up to the Murambi High Level Water Tanks in the hope of catching a glimpse of the very thin old moon rising. Instead there was a surprise appearance of mammatus clouds on the underside of a sunrise-illuminated band of altostratus cloud above.”
Stephanie Tilden Dorr in Wichita, Kansas, caught these clouds in June 2018. She wrote: “Mammatus clouds appearing exactly one hour after a hailstorm passed over. Twenty-five years in Kansas and I’ve only seen mammatus clouds this vivid one other time, years ago. So exciting!”
