yeah...
NHC runs those models constantly, but they generally won't put out any kind of full update until 5 AM, or whenever the data if fully available....
Thanks for posting those helpful links. There's a parallel discussion thread about potential damage to New Orleans on the Weather Underground site at this link:

By the way, anyone evacuating from New Orleans probably should skip Alexandria/Pineville as a potential destination. The hotels fill up instantly here and you'll probably be redirected to a shelter.
Prayers to everyone affected by this storm!
