Scripting fronts

The following is what I am using to download the ASUS frontal bulletins. I want the latest bulletin to always plot no matter what the clock time. This download doesn't appear to work and I get an http timeout ( 20 second countdown).

http://www.atmos.albany.edu/weather/dat ... ta\frt.dat

In addition I receive this in the legend after product,wxp,frt plot

Queue.fro front file header data not found sfc frontal depiction

and no fronts plot.

Can anyone give me a clue on what is wrong?

Thanks

Roy

Roy,

I find that by just simply using
download,http://www.hamweather.net/weather/asus0 ... ta\frt.dat
Fronts will do just fine all the time. This site uses a "latest" file, so you always have an up to date file.
I don't think they mind the traffic, especially since it is about a 1k download.

But if you really want to use Albany, you have to check their directory to find out the exact times the front files are posted. Seemed it was 1Z,4Z, 7Z, 10Z, 13Z, etc. so a script ran at 13Z had to use
download,http://www.atmos.albany.edu/weather/dat ... fronts.dat
because 13Z wasn't posted yet. Time tokens for fronts are complicated, and they varied specifically for every hour you want to do a run. That's why I used sites that use "latest" files. (I think NOAA does that, too)

Thanks

Thanks Wally.

Yes on the old DA2000 I had to go in every three hours and change the time.

Thanks for your swift help.
