...Weather Radar in San Joaquin Valley Gets Upgrade...

Modesto Vasquez

June 27, 2017

The weather radar used by the National Weather Service Forecast
Office in Hanford will be down approximately for the next two
weeks. The radar is expected back in service by Monday, July 10th.
Technicians will continue to install important technological
upgrades during this period. However damage to the radar pedestal
bull gear was discovered during the upgrade and a new gear-
bearing assembly will need to be installed by a depot level
technician team.

While work is being performed on the KHNX WSR-88D during the
outage, other radar coverage is available from adjacent radar
sites, including KDAX Sacramento, KMUX Monterey, KVBX Vandenberg,
KEYX Edwards AFB.

A crew will complete installing a new signal processor, which
replaces obsolete technology, improves processing speed and data
quality, provides added functionality, and supports IT security.

This is the first of four major upgrades, known as service life
extension projects, planned in the next five years to replace and
refurbish major components of the 20 year old WSR-88Ds and to keep
the radars operational into the 2030s. The 150 million dollar
investment is being made by the three organizations that use these
radars, NOAA`s National Weather Service, United States Air Force,
and Federal Aviation Administration. The other service life
extension projects include refurbishing the transmitter, pedestal,
and equipment shelters.

The tri-agency Radar Operations Center, which supports the
radars, estimates it will take about 10 months to upgrade the
signal processor on all 159 operational WSR-88Ds.

A tentative deployment schedule is available at:
