There is a major disconnect in communications between the NHC and the climate change people. In fact, not only do they not talk much with each other, they take potshots at each other on the various news sources I've seen or listened to.

Consider who is looking right and who is looking wrong....

Sea surface temperatures (SSTs) are higher. The North Atlantic Oscillation (NAO) is positive and there is a strong historical correlation between increased hurricane activity and the NAO in its current state. Combine that with the SST's and I'd say there's little question significant future chances of major hurricanes making landfall in the Gulf over the next few years IMHO.

And don't forget NOAA's prediction that La Nina will be in effect for the next six months at least. (La Nina typically reduces upper level shear in the Atlantic basin and therefore fosters Hurricane development.)

This is what I find most disturbing-- the game is changing and they are using an old model.
