Alex,

Yes, they are written by different persons...the outlooks are issued by one of the following:

Dr. Lixion Avila
Dr. Jack Beven
James L. Franklin
Miles Lawrence
Dr. Richard Pasch
Stacy Stewart

who are NHC/TPC Hurricane Specialists.

The most recent Discussion was written by Jamie R. Rhome, who is with NOAA.

You can tell who issued what forecast, as their names appear at the end of the statements. I believe that even within the NHC, different forecasters can issue rather divergent forecasts based upon the same data...their "style" if you will.

I'm not certain if the NHC guys issue Discussions as well, or if that is entirely separate. Maybe one of our Mets can clear that up.

Cheers,

LI Phil
