Louisiana is now in full preparedness/evacuation mode. The emergency managers were on television not long ago stressing the need to prepare and evacuate in an orderly manner. Given less than a day's lead time since the track shifted and still 2 days to landfall, there's not much else you can do. It is simply too expensive to begin planning evacuations for the city when the projected path takes the storm into Panama City, FL with no real signs of a substantial shift west until within the 3 day window. Simply put, this storm is reminding us that we still don't know a lot about these systems and must rush to make preparations when things do change. Watches were placed in accordance with policy; shortly thereafter, evacuations and the like went into effect. It's about the best you can do right now, unfortunately.
