The word "nimbus" itself means "rain cloud" in Latin.

Here's a breakdown of different types of nimbus clouds and the weather they bring:

* Cumulonimbus: These are the most powerful storm clouds, responsible for heavy rain, thunderstorms, hail, tornadoes, and even floods.

* Nimbostratus: These clouds bring steady, widespread rain or snow, often for extended periods. They typically cover the entire sky and have a dark, gray appearance.

So, whenever you see a cloud with "nimbus" in its name, you can expect some form of precipitation!
