NOAA data is not updating

Hello all,

NOAA is upgrading some of their servers and ran into some issues which is delaying the output of their weather data. There is no ETA for when this will be fixed but I’ll keep you updated.

Affected data sources are:

  • GFS
  • HRRR
  • NAM3
  • NAM12
  • Storm tracks
  • NWW3

Cheers, Duane.


Thanks for the heads up. I was wondering if something similar to last time had happened. Sounds like they’re trying to prevent that from happening again which is much appreciated if true.

Thanks as always for the awesome app!


Not sure what happened but it was supposed to be a 3-6 hour upgrade of their systems and it sounds like it went south. Here is my last update from last night. Sounds pretty stressful in the office.

I’m currently semi-manually downloading the big GFS files (~90GB) to update GFS and also looking at this alternative fast downloading process.


A quick update. NOAA has restored some services but my scripts are still struggling to update the data.

I have found a work around and have it working for GFS. YAY. I just need to update my other scripts for HRRR, NAM and MWW3 (waves). I hope to get this all done today.

Thanks for your patience.

Cheers, Duane.


HRRR is back now. Yay!

Will work on MWW3 wave data now.

Unfortunately the NAM 3km and NAM 12km is still unavailable on the NOAA servers to be processed :frowning: but I’ll keep check for it.


MWW3 wave data is back up.

It looks like NAM 3km and NAM 12km is updating on the NOAA servers. I hope to get these going tonight.


OK, now NAM 3km and NAM 12km is all updating except for snow data - I’ll work on this tomorrow. Hopefully, it keeps updating.

In the process of fixing these I broke CAMS air quality updating but I’ll look into this tomorrow as well.

Cheers, Duane.


@duane Appreciate All Your Hard Work Thank You :+1::beers:


Finally, after a week of disruptions we are back and stronger than last time.

Snow is all fixed and I fixed the long term bug of GFS snow not working :slight_smile:
