Nimbus clouds are associated with rain or snow, depending on the temperature.

Here's a breakdown:

* Nimbus is a Latin word meaning "rain cloud."

* Nimbostratus clouds are dark gray, thick, and produce continuous rain or snow.

* Cumulonimbus clouds are towering, thunderhead clouds that can produce heavy rain, thunderstorms, hail, and even tornadoes.

So, while the word "nimbus" itself implies rain, it's important to specify the type of nimbus cloud to understand the specific weather it brings.
