When Did Hurricane Katrina Occur?

Hurricane Katrina made landfall on Monday, August 29, 2005, causing a massive amount of damage in New Orleans and other coastal areas of Louisiana. The hurricane itself was devastating, but the New Orleans' levee system failed, flooding the city and causing a disaster.

According to the New Orleans Times-Picayune, August 29, 2005, was a day that has forever changed New Orleans. Hurricane Katrina first appeared as a tropical depression on Wednesday, August 24, 2005. By Sunday, August 28, the storm had been upgraded to a hurricane that developed to Category 5 proportions. New Orleans' mayor ordered a citywide evacuation at 9:30 a.m. on the 28th, an order that some ignored or could not comply with, leaving thousands of residents vulnerable both to the storm and the resulting levee flood damage.
