[Ncep.list.idp.mrms.users] OPEN - TID: 809080283 - IDP - URGENT: Paducah radar data not being used in MRMS (since at least12z)?

To all,

A summary of what IDP Onboarding has provided concerning this urgent ticket.

This is a recap of this morning's phone conversations.  Initially we
thought this was an MRMS ingest issue so we restarted processing on KPAH
radar (vm-lnx-mrms-sr17a). This is before we got the email saying it is a
hardware failure at the site.    Since some of the data is coming in for
the KPAH radar,  MRMS does not know it has to fill in from the other
radars.   In order for them to fill in we need to remove KPAH from MRMS
completely. This requires a config file change and a restart of MRMS
processing on that VM.   The problem with this is that it would cause WFO
Paducah  to lose the local radars products for KPAH which are still coming
in. Based on this I understand you do not want us to make the change and we
will stand down.
