Remember when Bush said this?

"I don't think anybody anticipated the breach of the levees."
September 1, 2005

Well, the Dept of Homeland Security apparently knew 48 hours ahead of time.

In the 48 hours before Hurricane Katrina hit, the White House received detailed warnings about the storm's likely impact, including eerily prescient predictions of breached levees, massive flooding, and major losses of life and property, documents show.
...
The NISAC paper warned that a storm of Katrina's size would "likely lead to severe flooding and/or levee breaching" and specifically noted the potential for levee failures along Lake Pontchartrain. It predicted economic losses in the tens of billions of dollars, including damage to public utilities and industry that would take years to fully repair. Initial response and rescue operations would be hampered by disruption of telecommunications networks and the loss of power to fire, police and emergency workers, it said.

The best part of waking up, is incompetence in your cup.
