As a short update (also mentioned in this thread), it seems like NOAA has decided to stop distributing this data openly. Unfortunately, this means that we will have to find an alternative source with the same quality, which is proving to be a challenge. We will try to make this happen as soon as possible, but it could take time! You can read the official message from NOAA here.
We realize that these are some of the most useful weather layers in our collection, so we apologize for the inconvenience that this causes in the meantime.
Kind Regards,
Malte
