Clouds that resemble eggs are called mammatus clouds.
These distinctive clouds have a series of bulges or pouches that hang from the base of a larger cloud, typically a cumulonimbus raincloud.
Mammatus clouds are often associated with severe weather and can be a sign of thunderstorms or tornadoes.
The word "mammatus" comes from the Latin word for "udder," which describes the shape of the cloud pouches.
While they may look fluffy and harmless, mammatus clouds are a sign of turbulent air and can be a warning of severe weather.
