Katrina is a German name meaning "pure".
How on earth the people who name these natural atrocities ever came up with Katrina is beyond me.
Other more fitting names?

Honestly, i think they should think about renaming her. I wouldn't call her pure. I'd call her all of the above, and then some.
The ongoing devastation as a result of this catastrophe is horrific. I encourage everyone to pray for the souls of the dead, the dying, and for those who will live through this.
