Public Information Statement
National Weather Service Juneau AK
600 PM AKDT Tue Sep 12 2017

The weather radar on Biorka Island used by the National Weather
Service Forecast Office was brought down on Sep 12th and will be
down for approximately one week for technicians to install an
important technological upgrade. The work on the WSR-88D has been
scheduled to minimize any potential impacts to office operations and
will be delayed if hazardous weather is forecast.

During the outage, radar coverage will be unavailable.

A crew will install 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
these radars operational into the 2030s. The $150M investment is
being made by the three organizations that use these radars, the
NOAA 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.
