Hurricane forecast models (the same ones that were used to predict Katrina’s path) indicate a tendency for more intense (but not overall more frequent) hurricanes when they are run for climate change scenarios (Fig. 1).

Figure 1. Model Simulation of Trend in Hurricanes (from Knutson et al, 2004)

In the particular simulation shown above, the frequency of the strongest (category 5) hurricanes roughly triples in the anthropogenic climate change scenario relative to the control. This suggests that hurricanes may indeed become more destructive (1) as tropical SSTs warm due to anthropogenic impacts.

As far as I can tell, Katrina and Isaac are almost Identical at this point.

corrections Always welcomed.

The NHC Still has very little in the way of Intensity predictions.

and the only thing that's changed in NO, is that it's 7 inches lower in elevation and
the GOM is at least 3 inches higher.
