With a disaster of this magnitude, there are so many facts and figures thrown around. Keeping up can be exhausting.
Unless you're familiar with the Gulf Coast region, it can be tough to get your head around the particulars of this national tragedy.
Katrina ravaged roughly 650 miles of coastline from the Florida Panhandle to Louisiana.
Compare that to a map of Michigan and its roughly equivalent to Michigan City all the way around to Port Huron.
It's estimated that 80 percent of New Orleans is flooded, which is like taking the city of Lansing and multiplying it by five.
More than 12 inches of rain fell in a 30-hour period; that's about 40 percent of Michigan's annual rainfall.
"If one looks at pressure on its peak on Sunday, [Katrina] would rank fourth strongest in the Atlantic basin in recorded history," said Jeff Andresen, associate professor of agricultural meteorology at Michigan State University.
Andresen said we may not know the true magnitude of Katrina until some time next week.
