This is an image of the near real-time wind field of Major Hurricane Katrina. Courtesy of the crews and staff at the Hurricane Research Division. Who, by the way, have been providing a lot of the data and updates this afternoon and evening. Along with the regular updates from the AFRES Hurricane Hunters.

This is only an example of the wind fields as they were sampled at that time and Does Not reflect prsent or Future wind fields.

However...since there is a Strong Probablility that Major Hurricane Katrina will be at the current wind profile as she makes landfall.
This should serve as a rough guide, Only!
