All signs that I've seen show that it's related to natural variability. There could be some impact of global warming, but its role is probably a secondary or tertiary role.

The only reason you don't see a cone is because it's moving so slowly. The models are still all over the place.

We're not ruling out anything at this point. It's just something to watch.

It has weakened considerably and it looks like it will take a more westward course than we first anticipated.

Residents of Louisiana eastward to Florida should monitor this storm system.

We feel pretty confident that someone will [get hit]. We're forecasting a major hurricane for the United States East Coast.

The season is not over by any stretch of the imagination. If we didn't get anything it would be really rare.

If Katrina had been 30 to 40 miles to the west, it could have been a different story. It did not score as bad a hit [on New Orleans] as it could have. But it's still pretty bad. I doubt anyone will really be disappointed that they left.

The prolonged nature of the storm could increase the threat of coastal erosion.
