1 September 2008 (from AFP) - Torrential rain and winds from Hurricane Gustav lashed the US Gulf coast early today after nearly two million people fled the killer storm. Hundreds of troops were sent into New Orleans after what is being called the biggest evacuation in US history. "The outer edge of the storm is already over the Mississippi Delta and going in toward New Orleans now, according to radar," National Hurricane Center meteorologist Patricia Wallace told AFP. The eye of the storm was not expected to make landfall until later. At 0600 GMT, the heart of Gustav was 275 kilometers southeast of New Orleans, moving towards the city at 26 km an hour.
