Final Update: Work by the power company has been completed and the fractured cable has been restored. All connections between NESDIS and NCEP now appear nominal as if 1820Z.
Topic: SAB and NESDIS Product Outages
Date/Time Issued: August 11, 2021 1951Z
Product(s) or Data Impacted: SAB Tropical, Volcano, Fire, and Precipitation products
Date/Time of Initial Impact: August 10, 2021 1800Z
Date/Time of Expected End: August 11, 2021 1820Z
Length of Outage: 24 hours 20 minutes
Details/Specifics of Change: A cut network cable has resulted in a loss of communication between NCEP and SAB. Reportedly, the local power company is onsite and has determined that three power poles need to be replaced before the fiber can be repaired.
The following SAB products are affected:
Tropical - All tropical cyclone position and intensity estimates not making it into OPAH and the ATCF.
Volcano - All Volcanic Ash Advisories and Volcanic Ash Graphics are not making it to the OSPO and SSD web pages at
Washington VAAC Homepage (noaa.gov)
Current Volcanic Ash Advisories - Washington VAAC - Satellite Products and Services Division - Office of Satellite and Product Operations (noaa.gov)
And also through the GP5 Listserve
Fire - Fire and Smoke VGF files not being disseminated to NCEP Centers
Precipitation - All Precipitation text products are not being disseminated to the SPSD Precip Page
In addition – this outage is affecting non-PDA data distribution from NESDIS to multiple NOAA and DoD sites. NCEP access to NESDIS McIDAS servers is down, resulting in a data loss to N-AWIPS, CPC, NHC, and AWC (and possibly others; primarily Himawari and Metosat data). We are experiencing connection failures with DoD sites AFWA, NAVO and FNMOC.
