Isaac a Threat to New Orleans?

GFS Model run shows Issac hitting New Orleans as Category 3 storm in 3 days..

Repeat after me: Just one model, just one run. Just one model, just one run. Deep breaths. Just one model, just one run. But with just over 72 hours until the night when a reliable computer model is calling for a 125 mph Category 3 hurricane to directly hit New Orleans from the southeast, then stall out northwest of the city and dump copious rains… it may be time to dust off & review those evacuation plans, lest they be needed tomorrow. Yes, tomorrow. It takes time to evacuate New Orleans, if an evacuation is needed. Decisions need to be made soon.

In other words, if Isaac is going to hit New Orleans, it could be bad as Katrina, and it's getting late to to prepare in anticipation.

Maybe they should send Biden...
