October 31, 2019

On or about Thursday, October 31, 2019, at 800 AM Central
Daylight Time (CDT), 1300 Coordinated Universal Time (UTC), the
NWS will change public facing dissemination system webpage URL
base address locations; migrating from
https://www.nws.noaa.gov
to
https://www.weather.gov

After this change, all the affected dissemination system webpage
links currently re-directed to the new locations will cease to
function. Thereafter, users will see a 404 error when attempting
to access the old URL base address for each respective
dissemination system.

The affected dissemination system URLs include:
https://www.nws.noaa.gov/nwr
https://www.nws.noaa.gov/nwws
https://www.nws.noaa.gov/emwin
https://www.nws.noaa.gov/iscs

and all subordinate webpage URLs.

POSTPONED: Due Critical Weather Day (CWD) declaration, the GOES-15 (GOES-West) SXI Outage has been rescheduled to October 29, 2018.

Subject: GOES-15 (GOES-West) Satellite Drift to 128-degrees West
Commencing 2015 UTC, October 23, 2018

The GOES-West satellite transition from GOES-15 to GOES-17 is
scheduled to commence at 2015 UTC, October 23, 2018, with the drift
of GOES-15 from 135 to 128-degrees west. The transition is scheduled
to be completed on December 10, 2018, with GOES-17 declared as the
operational GOES-West satellite.

The GOES-15 EMWIN transponder will remain operational throughout the
0.88-degree/day drift to 128-degrees west. Receiving stations with
fixed antenna installations are likely to experience degradation or
loss of signal lock should the satellite move outside the receiving
antenna's effective beam width. Users should consider incrementally
re-orienting their antennas to maintain an effective signal-to-noise
ratio and signal lock during the GOES-15 drift.

The schedule of events for GOES-15 and GOES-17 is provided below.
Additional details are available from the NESDIS web site:
https://www.goes-r.gov/users/transitionToOperations17.html

DATES EVENTS NOTES
----------- ----------------------------- -------------------
OCT23-NOV01 - GOES-15 drift from 135 to - All instruments
  128W and services
    remain operational
OCT24-NOV13 - GOES-17 drift from 89.5 to - HRIT/EMWIN
  137.1W disabled
NOV15 - GOES-17 activated  
DEC10 - GOES-17 declared the  
  Operational GOES-West  
  satellite  

The simultaneous operations of the EMWIN broadcast on
GOES-14(105W) and GOES-15(128W); and the HRIT/EMIWN broadcast on
GOES-16(75.2W) and GOES-17(137.1W) is scheduled to remain in
effect through May 2019.

The close proximity of broadcast frequencies and geosynchronous
orbits of the GOES-15 and GOES-17 satellites may cause EMWIN-15
users to experience interference from GOES-17. Users are
encouraged to make further adjustments in their antenna
orientation to reduce interference issues.

EMWIN virtual channels 20, 21 and 22 on the GOES-16 and 17
HRIT/EMWIN broadcasts will not be operational until 2019.
Users are reminded to use products on the GOES-14 and 15 EMWIN
satellite broadcasts for operations, and to refrain from using
products appearing on channels 20, 21 and 22 in the GOES-16
and 17 HRIT/EMWIN broadcast until declared operational by the NWS.

Subject: GOES-13/14/15/16 Fall 2018 Solar RFI

NESDIS has provided the following information concerning the
potential for outages of the GOES data stream, including EMWIN.

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. 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.

The US National Weather Service (NWS) Headquarters will perform
urgent maintenance on electrical systems supporting the Emergency
Managers Weather Information Network (EMWIN) services commencing
0900 UTC, April 7, 2018.

Expected EMWIN service impacts:

A. FTP server - loss of service.
B. ByteBlaster servers - negligible impact.
C. GOES 14 or 15 EMWIN satellite broadcast - no impact.
D. GOES-16 HRIT-EMWIN satellite broadcast - no impact.

Date/Time of Initial Impact: April 7, 2018 0900 UTC

Date/Time of Expected End: April 9, 2018 1300 UTC

The EMWIN service disruption can be expected to last as long as
52 hours. Full service may be restored sooner. Should users
experience any additional service issues or problems, please
notify the NWS EMWIN Support at:

nws.emwin.support@noaa.gov

A 'Critical Weather Day' will not postpone this maintenance
activity.

Topic: NOAA Wallops Command & Data Acquisition Station (WCDAS) Facility Power Outage

Date/Time Issued: March 26, 2018 2115 UTC
Product(s) or Data Impacted: All WCDAS data and other operational services
Date/Time of Initial Impact: April 3, 2018 1200 UTC
** NOTE: The EMWIN satellite broadcast outage may commence any time after April 2, 2018 2045 UTC **
Date/Time of Expected End: April 5, 2018 2359 UTC
Length of Outage: 48 to 60 Hours

Details/Specifics of Change:

The NOAA Wallops Command and Data Acquisition Station (WCDAS) is planning an entire site power outage on Tuesday, April 3, 2018. The outage is required to perform maintenance and repairs on the station's electrical power system. The power outage can be expected to last as long as three days although the goal is to complete the work within two days.

It is likely there will be an outage of the 1692.7 MHz Emergency Managers Weather Information Network (EMWIN) broadcast for the duration that WCDAS is down for both GOES-14 and 15. If there is an outage, users are asked to utilize GOES-15's LRIT broadcast, the NWS FTP or ByteBlaster services for EMWIN continuity of operations. Additionally, there will not be any NOAA-18 and NOAA-19 HRPT data from WCDAS.

It is not anticipated that dissemination of other data to users will be impacted during this power outage. However, if unforeseen data outages occur, users will be notified as information becomes available.

If a 'Critical Weather Day' is declared, the event will be rescheduled for April 10, 2018.
