Robert,

I am forwarding this to SSEC for review.

>I have been having problems the last two days with McIDAS and the 12Z
>AVN run.   Looking at my thinned grids in the GEMPAK directory
>I see that the file is normal in size and I can produce images
>through my web page for the area of concern (Antarctica, where
>I am now).  These are used to make graphics for briefings.

>However, I use McIDAS to make most of the images and I cannot
>produce them.  When I do a dmap.k GRID56, I see that the GRID files
>are less than half of what they should be, and the same image
>that I produced with GEMAPK (10m winds) is missing when I 
>do the same with McIDAS.  I saw this 12Z yesterday, but not 00Z
>today.  I pointed my ADDE server to yours and got the same result.

>Any ideas?

>Thanks,
>Robert Mullenax
