A cumulonimbus incus (Latin incus, "anvil") also known as an anvil cloud is a cumulonimbus cloud which has reached the level of stratospheric stability and has formed the characteristic flat, anvil-top shape. A cumulonimbus incus means that the thunderstorm is in its mature stage, succeeding the preceding cumulonimbus calvus stage. Cumulonimbus capillatus is a sub-form of cumulonimbus incus.

A cumulonimbus incus is a mature thunderstorm cloud and it can produce many dangerous elements.

Cumulonimbus clouds can be powerful. If the correct atmospheric conditions are met, they can grow into a supercell storm. This cloud may be a single-cell thunderstorm or one cell in a multicellular thunderstorm. They are capable of producing severe storm conditions for a short amount of time.
