Conclusions• Pushed water away from the coast in much of central and

western Louisiana, then pushed water against the coast• Winds blew along or away from the shore in the early

stages of the storm• Only when the winds were directed toward shore did

significant surge build against the coast• Surge then spilled inland

• In lakes and bays, easterly winds blew water against west-facing shores and structures

• Consistent winds in SE Louisiana pushed water onto the shelf and against levees along the Mississippi River delta
