Mammatus clouds over transcanada highway near the Kananaskis turn off and the road check by police (due to flooding at Canmore), Alberta, Canada.

Mammatocumulus (meaning “mammary cloud” or “breast cloud”), is a meteorological term applied to a cellular pattern of pouches hanging underneath the base of a cloud. The name mammatus is derived from the Latin mamma (meaning “udder” or “breast”).
