Here's why:
* Funnel Cloud: A funnel cloud is a rotating column of cloud that doesn't reach the ground. It's a sign that conditions are ripe for a tornado, but it's not a tornado yet.
* Tornado Warning: This warning means that a tornado has been sighted or indicated by radar. It means immediate action is needed, as a tornado is a dangerous and destructive phenomenon.
Important Note: Even if a funnel cloud doesn't touch down, it's still a serious weather event. Always take shelter immediately if you see a funnel cloud or receive a Tornado Warning.
