I just wonder what purpose an "Eyewall warning" would serve. I mean, assuming we're talking about a major hurricane, the folks in the warning area are very likely to be without power, and I can't imagine NWR's and local radio stations' transmissions (that is, if the transmitters have power) will be heard by folks in the area. If nobody in the area is going to get the warning, why issue it begin with? Again, this assumes that the storm is a major hurricane, since most non-major hurricanes don't have "tornado-like" winds. In addition, all areas where the eyewall of a major hurricane is expected to make landfall should certainly be under a mandatory evacuation, so the folks in those areas shouldn't be there to begin with. Not saying that these people don't deserve to be served by the NWS, but they won't likely be able to get the "eyewall warning" anyway.
I understand the purpose of the warning, and I don't have a problem with warning for areas that are likely to experience "tornado-like" winds. However, it seems to be more academic than practical in terms of illiciting a response from those in the warning area.
