KATRINA TAKES AIM AT NEW ORLEANS

Now in the Gulf of Mexico, the hurricane is expected to hit Louisiana on Monday.

If it does arrive as a Category 4 (some are predicting a Cat 5 landfall), its current track will lay a huge hurt on New Orleans. The storm surge alone could doom the city.

Betsy hit in 1965 as a Category 3. Since then, an orderly evacuation plan has been developed. It requires 72 hours lead time. New Orleans is already a day late.
