Public Information Statement
National Weather Service Portland OR
1055 am PDT Fri Sep 30 2016

The National Weather Service (NWS) weather radar used by the NWS
Forecast Office in Portland, OR will be down for approximately three
days (72 hours) beginning mid-morning on October 3, 2016 for
technicians to install an important technological upgrade. The work
on the weather radar has been scheduled to minimize any potential
impacts to office operations and will be delayed if hazardous
weather is forecast.

During the outage, partial radar coverage will be available from the
Langley Hill radar, located on the central Washington coast and the
Medford radar, located in southwest Oregon.

A crew of technicians 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 weather radars and to
keep the 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.

A tentative deployment schedule is available:
