Hurricane katrina predicted?

Could better weather predictions have changed the outcome of Hurricane Katrina???

though people try to do their best in giving their weather predictions.. the weather is still unpredictable..

I don't know
but it sucked
I was in it
and I was on my porch for rita two
so I don't know

but for those who got bad bad bad water
or that died... yes probably

Didnt they know it was going to be a category 5 hurricane? I mean people were told it was a bad hurricane... Most people just tend not to leave, they cross their fingers and hope for the best (well atleast everyone in Miami does, Im assuming it isnt different anywhere else)... I dont think this was a weather predicition fault, the levee broke, not the weather people's fault...
