rain
normally cumulus clouds do not produce precipitation. It is cumulonimbus clouds that form rain or snow depending on the season.
Cumulus clouds can produce rain if they grow large and tall enough to develop into cumulonimbus clouds, which are known for generating thunderstorms and precipitation. When cumulus clouds reach this stage, they can release rain.
cumulus
Cumulus clouds typically produce showers or thunderstorms. They form when warm air rises and cools, causing water vapor to condense into water droplets or ice crystals.
Cumulus clouds can develop into rain clouds, but they do not typically produce rain on their own. When cumulus clouds grow larger and combine with other clouds, they can form cumulonimbus clouds that produce precipitation.
Cumulus clouds can produce varying amounts of precipitation, typically in the form of rain showers. The amount of precipitation produced by cumulus clouds depends on factors such as the size and vertical development of the cloud, atmospheric conditions, and location.

cumulus
Cumulus clouds typically produce fair weather, consisting of fluffy white clouds with a flat base. They indicate stable atmospheric conditions and are often associated with light winds and dry weather. When cumulus clouds grow vertically and develop into cumulonimbus clouds, they can produce thunderstorms and heavy rainfall.
Cumulus clouds may bring rain, but not always. Whether or not a cumulus cloud produces rain depends on factors such as the atmospheric conditions, moisture content, and vertical development of the cloud. Cumulus clouds that grow into towering cumulonimbus clouds are more likely to produce rain.
Cumulus clouds are typically associated with fair weather, but they can produce snow if the clouds grow vertically enough to reach cold enough temperatures in the atmosphere where water droplets freeze and fall as snowflakes. This is more common in cumulonimbus clouds, which are larger and more vertically developed versions of cumulus clouds.
They don't. However, a cumulus cloud can develop into a cumulonimbus cloud (a.k.a. thunderstorm) under the right conditions. Even then conditions have to be specific for it to produce a tornado.
