20051021: Missing HRCN graphics in NMAP2 and web images?

Chris,

The text bulletins you attached from your NWX directory that have the
pattern WTNT2[1-5] KNHC are those bulletins which should also be decoded
by dchrcn using the supplied pattern:
DDPLUS  ^WT(NT|PZ|PA)2[1-5] (KNHC|PHFO)

Verify that your decoded YYYYMMDDHH.hrcn files exist and
are being decoded, if not check any recent modifications to
your pqact.conf file, and run the pqact test on your
pqact.conf file. The location for the decoded hrcn files that

made pqact.conf changes take affect that make pqact fail when reading

The files that contain WILMA today include:
2005102102.hrcn, 2005102108.hrcn, 2005102114.hrcn
These are being correctly decoded and plotted.

When plotting in NMAP2 using the data type MISC/HRCN, the default
attributes for the plot will be to include plotting of the wind/sea
radii. The "Edit Source" option allows the user to turn those and
other plotted parameters on/off.

In GPMAP, an example for including the wind/sea quadrant info and
forecast track is:
HRCN     = last|15;30;23;7|||YES|YES|YES|YES

The question you ask about plotting model tracks is accomplished through
the ATCF data which is a different product, such as is shown:

You can see how to set up the ATCF plotting and data here:

Similarly, the  ENCY parameter introduced in 5.8.3a. See:

Hi folks,

We have a feature here that I can't figure out what has happened. All of a sudden, yesterday, the plotting of the hurricane forecast track and wind radii has stopped occurring on our systems. This is true for both NMAP2 and for our scripts that make our web site images. Nothing has changed on our systems and the text files seem to be in place.

Here is what is on disk:
(Is this the correct product?)

I've attached two samples, one that worked and one that doesn't just in case something is wrong on our end.

The 10/19 15z plot is the last one that worked on our system.

Any thoughts on what may be wrong would be greatly appreciated.

Also, if you could provide an example of how you do the various model forecasts I'd really appreciate it. I just can't get the data to show up there either.

Thanks in advance for your time,

Chris H.
