There was a 5 minute outage this morning of NOAAport shortly after 14Z. Since
then, however, I have not seen any Canadian radar data on the SBN under the
header of “SDCN01 CWAO”.
I am wondering if they had an issue.

Subject: Change to NOAAPort / Satellite Broadcast Network (SBN)
Channel Alignment: Effective December 9, 2024
The NWS has studied the existing NOAAPort/SBN/NWWS channel
alignment, bandwidth usage, prioritization, and delay times.
This study identified that reorganizing the data on the various
channels will improve the timeliness of distributed products.
The first change recently implemented was to move gridded binary
(GRIB), GRIB two (GRIB2), and Binary Universal Form for the
Representation (BUFR) formatted data from the NMC channel to the
NMC2 channel. Refer to Service Change Notice (SCN) 24-54:
https://www.weather.gov/media/notification/pdf_2023_24/scn24-
54_channel_realignment_to_SBN_aaf.pdf for more details about
this change.
The space freed on the NMC channel provided by the first change
allows the next change to occur, adding Canadian Radar data to
the SBN. (Channel: NMC | Priority: 0 | Bandwidth: 20 | Port:
1201 | PID: 101). However, only the following 23 of 31
available radars will be added to minimize SBN impact, and reflect
those
adjacent to the United States:
World Meteorological Organization (WMO) header: SDCN01 CWAO
CASSS - Silver Star Mountain, British Columbia (BC)
CASAG - Aldergrove, BC
CASSM - Strathmore, Alberta (AB)
CASSU - Schuler, AB
CASBE - Bethune, Saskatchewan (SK)
CASFW - Foxwarren, Manitoba (MB)
CASWL - Woodlands, MB
CASDR - Dryden, Ontario (ON)
CASMR - Montreal River Harbour, ON
CASET - Exeter, ON
CASBI - Britt, ON
CASKR - King City, ON
CASFT - Franktown, ON
CASNE - Thunder Bay ON
CASBV - Blainville, Quebec (QC)
CASSF - Ste-Francoise, QC
CASMA - Mt Apica, QC
CASVD - Val d'lrene, QC
CASCM - Chipman, New Brunswick (NB)
CASGO - Gore, Nova Scotia (NS)
Additionally, more WMO Headers containing model data, related to
phase 1, were discovered and need to move. (Channel: NMC |
Priority: 0 | Bandwidth: 20 | Port: 1201 | PID: 101) to
(Channel: NMC2 | Priority: 5 | Bandwidth: 30 | Port: 1203 | PID:
103):
^(MZ....) ^(LZ....): NAM Nested Model data
^(HC....) ^(HO....) ^(HP....) ^(HU....) ^(HV....): SSI GFS model
This data is expected to move on or about 1200 Coordinated
Universal Time (UTC) December 9, 2024.If a Critical Weather
Day has been issued, this change will be postponed to 1200 UTC
on the next non-Critical Weather Day for the following dates:
December 10, 16 and 17, 2024.
No change is expected to the data feed at the receiver. If no
issues are experienced, the configuration will remain in place.
If any issues are identified, the changes will be evaluated, and
a new implementation date will be determined.
We encourage all NOAAPort/SBN/NWWS users to closely monitor this
SCN during the transition period for updated information. If
you have any questions or concerns, please contact the focal
