Gus has really picked up the pace, he is out running the stronger storms and leaving them behind (to the south), thus they are not wrapping around the core/eye. This quicker motion is keeping him on more northerly path as the high above him has weaken and moved off to the east. It now appears that this high is not filling in fast enough to slow him down until well after landfall. The NHC line looks to be right on target and his current forward speed points to midday Monday landfall as a Cat 3. I believe he is simply moving too fast to gain strength regardless of sea temps. I'm just glad to see the streets of New Orleans are mostly empty, since the city will be on the "dirty" side of the storm this is shaping up to be a real mess
