anvil clouds

Flat-topped storm clouds

Anvil clouds are the distinctive flat-topped formations that spread outward from the tops of powerful thunderstorms, resembling a blacksmith's anvil in profile.

They form when rising air in a cumulonimbus cloud hits the tropopause and spreads horizontally, unable to rise further.

The presence of an anvil cloud signals a mature, intense storm system capable of producing severe weather including heavy rain, hail, and tornadoes.
