Starting around 1830Z, there is a wide-ranging NWS outage of NEXRAD level III products. Products are missing from our MyRadar usual upstream sources and from AWS. This may be related to a NOAAPORT uplink test that started around that same time. We are continuing to monitor, but, unfortunately, there isn't much we can do.

Maybe coincidentally, there is also an outage of MRMS-based lightning data. That outage also started around 1830Z.

We'll keep you posted
