...NWS Sacramento Weather Radar Outage For Heavy Maintenance May 16,
2017 to May 19, 2017...

The NWS Sacramento weather radar at Davis, CA (KDAX) will be down
for approximately three days beginning Tuesday, May 16 at
approximately 8 a.m. PDT. The radar is owned and operated by
NOAA`s National Weather Service and is part of a nationwide
Doppler radar network.

The maintenance work must be performed to keep the radar operating
far into the future. The radar is well maintained on a regular basis
by NWS electronics technicians who keep the radar at nearly 100% up
time. This heavy maintenance work 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 which
replaces obsolete technology and provides improvements to
functionality, IT security, and data quality and speed.

Because of the large scope of the work, once the maintenance begins,
the radar will not be able to be restarted until the project has
been completed. The work should be completed by 4 p.m. PDT, Friday
May 19, but it is possible that the work may finish a little earlier.

The schedule for this maintenance was chosen based on when the
impact of having the radar down would be least disruptive. During
the outage, neighboring radars at Beale Air Force Base (KBBX),
Eureka (KBHX), Hanford (KHNX), Monterey (KMUX), and Reno (KRGX) will
continue to provide coverage over parts of the area served by the
Davis, CA radar.
