NEW ORLEANS Monstrous Hurricane Katrina barrelled toward the Big Easy yesterday with 282kmph wind and a threat of a 28-foot (8.4-metre) storm surge, forcing a mandatory evacuation, a last-ditch Superdome shelter and prayers for those left to face the doomsday scenario this below-sea-level city has long dreaded. Katrina intensified into a Category 5 giant over the warm water of the Gulf of Mexico on a path to come ashore early yesterday in the heart of New Orleans. That would make it the city's first direct hit in 40 years and the most powerful storm ever to slam the city. I'm really scared, ... I've been through hurricanes, but this one scares me. I think everybody needs to get out.
