Let me just mention something about my experience with Emergency Management. Collier County (Southwest Florida), when we activate our Emergency Management Operations Center for hurricanes, we usually activate about 36-48 hrs in advance (when Katrina was close to the east Coast of Florida, we activated 24 hrs in advance because it would've been more of a rain event than a rain and wind event for us). But, depending on the degree of potential damage caused by a storm, sometimes our Emerg. Mgmt Operations Center will activate 72-96 hrs prior to landfall.
From what I've seen, they bring in a whole slew of people - everyone from the hospitals, school system (our schools are used for shelters), electrical (FP&L - Florida Power & Light -

It's a major production and our emergency management department is at least prepared for the worse even if we don't get anything bad. Because, quite honestly, you just never know what these hurricanes are going to do these days.
So, based on what you said about "they should've mobilized a week ago", how did you know that they didn't? They were probably on the ready after Katrina crossed South Florida into the Gulf.
