5 Hurricane Katrina to hit New Orleans? NEW ORLEANS, Louisiana (CNN) -- A solemn New Orleans Mayor Ray Nagin ordered mandatory evacuations Sunday as his city faced its worst fear -- the threat of a direct hit from a major hurricane that could swamp the low-lying city. August 28, 2005

6 By mid-morning Sunday, Katrina was a Category 5 hurricane with maximum sustained winds near 175 mph. It was expected to make landfall Monday morning. Category 5 is the most intense category on the Saffir-Simpson scale of intensity. Officials are particularly concerned about New Orleans because about 70 percent of the city is below sea level. The city essentially sits in a bowl, protected by a series of levies that keep the Mississippi River waters out. Nagin warned that Katrina's expected storm surge -- which could top 28 feet -- would likely topple those levies.

7 The last hurricane to score a direct hit on New Orleans was Hurricane Betsy, a Category 2 with 105 mph winds when it came ashore in Betsy killed more than 70 people, its storm surge overflowing the levees and reaching the eaves of many buildings. The levees are higher now, but Katrina is a stronger storm -- as strong as 1969's Hurricane Camille, which grazed New Orleans when it came ashore in Mississippi and killed more than 250 people. "After Betsy these levies were designed for a Category 3," said Sheriff Jeff Hingle of Placquemines Parish, just southeast of New Orleans. "You're now looking at a Category 5. You're looking at a storm that is as strong as Camille was, but bigger than Betsy was size-wise. These levies will not hold the water back. So we're urging people to leave. You're looking at these levies having 10 feet of water over the top of them easily."

10 NOAA HURRICANE HUNTER PILOT CAPTURES KATRINA AT HER MEANEST Sept. 1, 2005 NOAA hurricane hunter aircraft conducted ten long flights into and around the eye of Hurricane Katrina. Lt. Mike Silah got to see Hurricane Katrina up close and personal, especially when she was an extremely dangerous Category Five storm in the Gulf of Mexico. The day before the powerful and destructive storm made landfall on the USA Gulf Coast, Silah snapped a series of images capturing the eyewall of Katrina. Hurricane Katrina
