US officials say New Orleans levees sound

Levees in New Orleans have survived Hurricane Gustav so far, but parts of southern Louisiana remain in grave danger, federal emergency management officials said Monday. The hurricane slammed into the heart of Louisiana's fishing and oil industry with 110 mph winds Monday then faded as it moved inland, delivering only a glancing blow to New Orleans that raised hopes the city would escape the kind of catastrophic flooding brought by Katrina three years ago. Aircraft that were grounded due to high winds were to begin flying over stricken areas later Monday to make the first damage assessments.
