Storm surge (click here) was the main cause of death during Hurricane Katrina. In fact, it can be the most dangerous part of any hurricane, and it is only partly determined by wind speed (the aspect of a storm on which the hurricane categories are based). It occurs when strong winds from an approaching hurricane push water into the shore.
What makes this rise particularly dangerous is that it starts to build up before the hurricane makes landfall. So the coastal flooding from it can make evacuation procedures and the impact of a hurricane much worse....
