As of this posting the GFS, GFDL, CMC, and NOGAPS models are still available at the Penn State site:

Both the FSU and PSU sites which display these models are quite similar. Not sure if the PSU site will also become unavailable in the near future. I can't believe that FSU will no longer make the models available to the public. As a Florida resident, I'll be sure to let the powers that be at FSU know my opinion once I locate a contact name/email. And their timing is unbelievable--right before the start of the 2006 season.
