Howdy,

A reminder that this change just happened.

The NWS National Centers for Environmental Prediction (NCEP) Central
Operations (NCO) creates routine collectives of observational METAR data
in SAUS70 KWBC, SAUS80 KWBC, SAUS90 KWBC and their counterparts for
Special observations SPUS70, SPUS80 and SPUS90. These collectives
require manual intervention to add METAR stations to them. These are
then distributed over the SBN. Another product, SAUS99 KWBC, and the
Special observation counterpart SPUS99 KWBC contain any METAR observation
received every minute. Delivering SAUS99 and SPUS99 over the SBN rather
than the aforementioned collectives will provide more observational data
and more timely data to users of the SBN.

The replacement with SAUS99 and SPUS99 is expected to occur on or about
1200 Coordinated Universal Time (UTC), January 27, 2025. If a Critical
Weather Day has been issued, this change will be postponed until 1200 UTC
on the next non-Critical Weather Day.

So far, I have observed 265 SAUS99 products and 114 SPUS99 products cross the 
IDD since about 15 Z
