It's the worst natural disaster, of the century, in the US. But the tsunami disaster earlier is by far the worst and may just remain the worst natural disaster until the next century.
There were some natural diasters that I have been involved in that could still surpass Katrina in some respects. I found a list at

The two I would like to mention are:
"Great Midwest Flood," May 9, 1993: Seventeen hundred square miles were flooded in North Dakota, South Dakota, Nebraska, Kansas, Minnesota, Iowa, Missouri, Wisconsin and Illinois after record rainfall caused hundreds of breaches in levees along the Mississippi and Missouri rivers. Until Hurricane Katrina, this flood was considered the costliest in U.S. history with estimated damage of $20 billion. Fifty people were killed
Twisters, South/Midwest, April 3, 1974: In a period of 16 hours, 148 twisters touched down in 13 states (Alabama, Georgia, Illinois, Indiana, Kentucky, Michigan, Mississippi, North Carolina, Ohio, South Carolina, Tennessee, Virginia and West Virginia), killing 330 people and injuring 5,484 in a path covering 2,500 miles. More than 27,500 buildings were destroyed. Total property damage was estimated at $600 million..
In both cases, many (including myself) felt federal help was to slow and preperation was inadequate
