The National Weather Service and the National Hurricane Center...forecast the path of the storm and the potential for devastation with remarkable accuracy. National Hurricane Center Director Max Mayfield also gave daily pre-storm videoconference briefings to federal officials in Washington, warning them of a nightmare scenario of New Orleans' levees not holding...and flooding wiping out large swaths of the Gulf Coast. Mayfield also...personally called the governors of Mississippi and Louisiana and New Orleans Mayor Ray Nagin two days ahead of time to warn them about the monstrous hurricane.
