A Cumulonimbus Capillatus is a mature and powerful cumulonimbus cloud and can produce multiple severe weather.
- Lightning; this is a strong thunderstorm cloud and it is capable of producing bursts of cloud to ground and cloud to cloud lightning.
- Hail; hailstones may fall from this cloud if it is in a highly unstable environment (which favors a more vigorous storm updraft).
- Heavy rain; the cloud may drop several inches of rain in a short amount of time. This can cause flash flooding.
- Strong wind; gale-force winds from a downburst may occur under this cloud.
