Katrina took longer to build than Rita has so far. If Katrina hadn't stalled and then gone N N/E like it did, it would have hit about where Rita is heading except it wouldn't have been nearly as strong is Rita is getting. Katrina took about a day longer to get to 100mph winds and was a day more west then Rita is now.
-------------------- The safest way to deal with a potential Hurricane hitting you...is to leave and just not be there at all.
