The track forecast has not changed significantly, and the area from New Orleans to the Mississippi-Louisiana border is going to get a catastrophic blow. I put the odds of New Orleans getting its levees breached and the city submerged at about 70%. This scenario, which has been discussed extensively in literature I have read, could result in a death toll in the thousands, since many people will be unable or unwilling to get out of the city. I recommend that if you are trapped in New Orleans tomorrow, that you wear a life jacket and a helmet if you have them. High rise buildings may offer good refuge, but Katrina has the potential to knock down a high-rise building. A 25 foot storm surge and 30 - 40 foot high battering waves on top of that may be able to bring down a steel-reinforced high rise building. I don't believe a high rise building taller than six stories has ever been brought down by a hurricane, so this may not happen Monday, either. We are definitely in unknown waters with Katrina.
Hurricane force winds are now striking Louisiana. Katrina is 105 miles south southeast of New Orleans, and landfall is expected early Monday morning. Computer models suggest that more than 80 percent of buildings would be badly damaged or destroyed, he said.
