Which cloud type is often associated with precipitation and stormy weather?

Nimbus clouds are indeed the type associated with precipitation and stormy weather. The term "nimbus" specifically indicates that these clouds are capable of producing rain or other forms of precipitation. They are often dense and dark, reflecting their significant moisture content.

Nimbus clouds can often be seen as a sign of impending storms, as they frequently lead to heavy rainfall, thunderstorms, and sometimes even severe weather conditions. Unlike other cloud types, which may not necessarily indicate precipitation, nimbus clouds are a clear indicator that moisture in the atmosphere is condensing into liquid form, contributing to the likelihood of rain and associated stormy weather.
