White House Got Early Warning on Katrina: "The NISAC analysis accurately predicted the collapse of floodwalls along New Orleans's Lake Pontchartrain shoreline, an event that the report described as 'the greatest concern.' The breach of two canal floodwalls near the lake was the key failure that left much of central New Orleans underwater and accounted for the bulk of Louisiana's 1,100 Katrina-related deaths.
The documents shed new light on the extent on the administration's foreknowledge about Katrina's potential for unleashing epic destruction on New Orleans and other Gulf Coast cities and towns. President Bush, in a televised interview three days after Katrina hit, suggested that the scale of the flooding in New Orleans was unexpected. 'I don't think anybody anticipated the breach of the levees. They did anticipate a serious storm,' Bush said in a Sept. 1 interview on ABC's 'Good Morning America.'"
