No storm/tornado reports yet, however, I would say tommorow there will be many, but that will be peoples least worries.

I've never heard of this before. Anyone know what this is about?
Many offices that have had to deal with hurricanes in recent years have been doing this basically because there is no such warning to actually warn for the eyewall. I doubt if issuing tornado warnings for the eyewall has much effect though or does any good considering that many won't have access to the warning or will already be taking shelter because of the hurricane strength winds already ongoing.
Edit: I'll also add that because this storm will be making landfall quite a bit earlier than originally expected, this technique may actually have some use during this event . . . if those affected can receive the warning.

A. Actually, it is very common for tornado warnings to be issued when the eye wall of a significant hurricane moves onshore. This is owed in part to the massive angular momentum and spin in the individual thunderstorms within the eye wall.
B. The reason they are so short lived is because the thunderstorms themselves are unorganized and do not really last too long (unlike spring time storms in the plains). As a result, it is hard to have much lead time for warnings. A long lived tornado during a tropical storm or hurricane is not common at all.
C. Many of the verifications are made by eyewitness accounts and damage reports. If one area has maximized wind damage (and not the other areas nearby), then it most likely would have been a tornado that caused that damage since hurricane winds would have a more widespread damage pattern. Tornado damage will be very localized in most cases. As far as determining tornado damage vs. hurricane damage in an eye wall, good luck....pretty much impossible.

Which area are you speaking of?[/b]
think thats why the tropical depressions can sometimes become prolific tornado producers as there becomes enough breaks in the clouds to create enough instability vs good but not so extremely sheared out cells.
