Major Problem with advforecast2.php script: NWS Site Redesign???

[1080iAddict]

The icons are gone!  The printable forcast is gone!  NWS changed the site! This used to be for Glyndon, MD and now its gone!


http://forecast.weather.gov/MapClick.php?site=lwx&FcstType=text&MapType=3&site=lwx&CiTemplate=1&map.x=285&map.y=45&TextType=2

What is happening?  Am I going crazy?  It worked yesterday.  The site was down for 2 hours.  Now its all a different design.

Wow .. you are right. Checked mine and also gone. Whole new forecast page at NWS .. w/o Icons!!!! Now what .. we start all over?

I suspect when Ken sees this he'll come up with something.

Man.  I think we are SCREWED.  Ken is the king of weather sites and scripts but I don't see how he'll pull a rabbit out of his arse for this one.  The entire foundation for the script is gone!

Same here.......I'm sure Ken will come up with something.  Ken is a master at this forecast scripting.

Maybe no need for panic folks, that page currently has this message

"The NWS forecast web pages are currently defaulting to a zone based product due to technical difficulties. The point specific forecasts, with icons and the houly weather graph will return as soon as possible. Thanks for your patience.
NWS Baltimore, MD/Washington, D.C."

Thank you Niko. I tried to find something like that statement. The page just does not look right in my browser. Does not fit right.

Well, that's a new one for the transition.. before they did a 302 (temporary redirect) to the zone forecast out of www.crh.noaa.gov .. now they're just being "helpful" and pulling the text only.

Let me see what I can do about detecting that, then force a failover to the REAL zone forecast (hopefully with icons).

Ken

BTW... THANKS for all the kind words!  Let's see if there's a rabbit to find in this hat 

[saratogaWX]

Ok, here's the quick fix to detect this and fail over to your REAL zone forecast.

Change:

Code: [Select]

  if (preg_match('/Temporary|Location:/Uis',$html)) {
to

Code: [Select]

  if (preg_match('/Temporary|Location:|defaulting to/Uis',$html)) { in the TWO places it occurs in the source.

I've updated advforecast2.php (for the faint of heart doing PHP updates )

http://saratoga-weather.org/advforecast2.php?sce=view

Tested the failover with 1080iaddicts settings (http://saratoga-weather.org/advforecast2-testing.php ) and works fine.

Best regards,
Ken

Works like a charm Ken, thanks for your great coding. The Saratoga link does NOT work however!

Question though, is this an automatic check and re-direct and will go back to icon page when NWS fixes or we will have to change code again?

I'm a little confused (as always) with where to change it in my PHP Ajax code

Ken,

That code works, i.e., I get the icons and the forecast.  But I also get this on the bottom of the page:

Code: [Select]

My hope is that the issue is in fact temporary and will revert soon.  But is there an easy fix for the scary gobbelygook?   

Thanks for your help by the way...
