A funnel cloud is a tapered, rotating cloud created by convection and conflicting wind directions. If it reaches the surface, it becomes a tornado, or a waterspout, but only a small minority of funnel clouds become tornadoes.
Funnel clouds can also indicate weak tornadoes that don't have a visible portion reaching the ground. A destructive tornado could look like a funnel cloud if the air is unusually dry, preventing the formation of cloud material all the way to the ground. In this case, spinning debris would be the only indication of destructive winds.
