An atmospheric river will continue to bring gusty winds, moderate to heavy rainfall, and potential flooding to southern California and the southern Great Basin through Sunday. Periods of heavy snow will continue as well above 7,000 feet over the Sierra Nevada mountains associated with this atmospheric river. Read More >

Date/Time Issued: February 11, 2022 2100 UTC
Product(s) or Data Impacted: GOES-14/15/16/17 Imager and Sounder Data plus Ancillary Services (GVAR, SAR, LRIT, EMWIN, DCS, GRB, etc.)
Date/Time of Initial Impact: February 22, 2022 1704 UTC
Date/Time of Expected End: March 9, 2022 2152 UTC
Length of Outage: See table in details.
Details/Specifics of Change: The potential for solar radio frequency interference (RFI) with a satellite downlink circuit will occur whenever the Sun passes into the beam of the ground station receiving antenna.
We received the following information from our Mission Operations Division concerning the potential for outages of the GOES data stream including GVAR (GOES Variable) Imager and Sounder, SAR (Search and Rescue), High Rate Information Transmission (HRIT), Sensor Data (SD), Telemetry and Command (T&C), Weather Facsimile (WEFAX), Data Collection Platform Report (DCPR), Multi-use data link (MDL), Raw Data Link (RDL), etc.
The Wallops and Fairbanks Command and Data Acquisition Stations (CDAs) and Environmental Satellite Processing Center (ESPC) receiving antennas may experience periods of Solar RFI as predicted below. Solar RFI can cause loss of telemetry lock and command capability, as well as degradation or loss in the GVAR data.

Subject: Static Radar Image Files Return to EMWIN
Services March 24, 2021
The broadcast of static Radar Image files suspended on December 16, 2020, as announced in
Service Change Notice 20-117, have resumed over the Geostationary Operational Environmental
Satellite (GOES)-East and West High-Rate Information Transmission (HRIT) / Emergency Managers
Weather Information Network (EMWIN) satellite broadcast on virtual channel 21.
These files concurrently returned to the enterprise EMWIN File Transfer Protocol (FTP) image archive file server:
https://tgftp.nws.noaa.gov/SL.us008001/CU.EMWIN/DF.xt/DC.gsatR/OPS/
Further information on the Radar products is documented under

Subject: Updated: Static Radar Image Files Temporarily Suspended
on EMWIN Services, Effective December 16, 2020
Updated to correct the date for the return of the Static Radar Image Files on the EMWIN services from February 26, 2021, to a
date to be determined.
On or about December 16, 2020, NWS temporarily suspended 10 static Radar Image files sent over the Geostationary Operational
Environmental Satellite (GOES)-East and West High Rate Information Transmission (HRIT) / Emergency Managers Weather
Information Network (EMWIN) satellite broadcast on virtual channel 21. These products are published on the enterprise EMWIN
File Transfer Protocol (FTP) archive file server. The products will be suspended pending completion of the NWS migration to the
new Ridge 2 radar product generation services.
The suspended Radar products are listed/documented under Title-03 through 12, in the EMWIN Image and Text Data Capture
Catalog: https://www.weather.gov/media/emwin/EMWIN_Image_and_Text_Data_Capture_Catalog_v1.3b_r180817.pdf
The static Radar Image files should return to the EMWIN services by a date yet to be determined. A separate NWS Public
Information Statement (PNS) will be released when the suspended static Radar files have been reinstated on the EMWIN services.
In the interim and effective on or about December 16, 2020, Users may obtain Ridge 2 static radar image files for individual
radar sites at the following Ridge 2 services URL: https://radar.weather.gov/ridge/lite/
Send questions on the information in this bulletin to:
