3. CHALLENGES AHEAD OPERATIONAL CHALLENGES -- Limited window of opportunity to close the system

4. Track uncertainties less than 72 hours from first landfall Hurricane Isaac’s uncertain path Storm formation just south of Louisiana coastline Tropical Storm Lee developing

5. CHALLENGES AHEAD OPERATIONAL CHALLENGES -- Limited window of opportunity to close the system -- Complex machinery = complex operating procedures

6. Barge Gate • Damaged the second time the barge was placed in the closed position • Requires long lead time to close the gate • Can only be effectively operated under the right environmental conditions

7. CHALLENGES AHEAD OPERATIONAL CHALLENGES -- Limited window of opportunity to close the system -- Complex machinery = complex operating procedures -- Required evacuation of vessels and all floatable in corridor

8. Gustav Impacts and Vunerabilities • Coast Guard RNA – evacuation of barges and ships • Will not address pleasure craft • Will not address other floatables that could damage fragile I-Walls Source: David Grunfeld / The Times-Picayune Source: Eric Gay, Associated Press Source: Trinityyachts.com

9. CHALLENGES AHEAD OPERATIONAL CHALLENGES -- Limited window of opportunity to close the system -- Complex machinery = complex operating procedures -- Required evacuation of vessels and all floatable in corridor -- Extraordinary coordination required (especially between federal agencies)
