- Mammatus clouds do not indicate any threat of tornadoes or violent weather
- W950908S
- The forward, downwind side of a storm anvil may exhibit mamma ahead of the storm’s arrival. Contrary to popular belief, the Mammatus clouds do not indicate any threat of tornadoes or violent weather in themselves and any such event is coincidental. However, the presence of these odd clouds does suggest that a strong storm is or was nearby.
