There are several private weather companies who have created their own scale and it helps their clients tremendously. I know of one that has a scale that includes wind speed, size, surge and rain. It actually works really well.
I guess my point is: This is not a new idea brought on by the AGW crowd. It's an idea which has been suggested by the pro-mets for years. It's just the NHC is so antiquated they don't want to mess with their golden calf and have the headache of re-training the public.
The AGW crowd may not have originated this idea, but you know they will parley it into “proof” of their unholy religion.
