Which clouds don't produce rain?

Clouds that typically do not produce rain include cirrus, stratus, and altocumulus clouds. Cirrus clouds are high-altitude, wispy clouds made of ice crystals, while stratus clouds are low, uniform clouds that can produce drizzle but generally do not result in significant precipitation. Altocumulus clouds can occasionally bring light rain but often do not produce substantial precipitation. Overall, these cloud types are more associated with fair weather or light moisture rather than heavy rainfall.
