Re: wilma on the way

If you want to look at the vorticity output. You will have to select the "upper air" section of the particular model that you are using.
It is possible to have a vortice (spin) at the surface and not at higher level...example: tropical depression or wave. It's also possible to have an elevated vortice that may or may not develop a surface reflection.

Similar to a Funnel Cloud and a Tornado. The funnel cloud is elevated and the Tornado is on the ground. By NWS definitions.

When in doubt, take the word of the National Hurricane Center.
