...NWS San Francisco Bay Area/Monterey Weather Radar Offline For
Upgrade May 22-25, 2017...

The NWS San Francisco Bay Area/Monterey weather radar at Mt.
Umunhum, CA (KMUX) will be down for approximately four days
beginning Monday, May 22 at approximately 9 a.m. PDT. The tri-
agency radar is operated by NOAA`s National Weather Service, the
Federal Aviation Administration and the United States Air Force.

The upgrade must be performed to keep the radar operating far
into the future. This upgrade is part of a nationwide project to
extend the service life of all 159 Doppler weather radars (WSR-
88Ds), which were designed in the 1980s and installed in the
1990s. Specifically, a new signal processor will be installed
replacing an obsolete technology and provides improvements to
functionality, IT security, and data quality and speed.

Because of the large scope of the work, once the upgrade begins,
the radar will not be able to be restarted until the project has
been completed. The work should be completed by early Thursday
morning, May 25.

During the outage, neighboring radars at Eureka (KBHX), Hanford
(KHNX), Sacramento (KDAX), and Vandenberg (KVBX) will continue to
provide coverage over parts of the area served by the Mt.
Umunhum, CA radar.
