Weather Radar in Fort Smith, Arkansas (KSRX) Gets Upgrade

Contact: Robert Darby 918-832-7838

March 3, 2017

The weather radar (KSRX) used by the National Weather Service
Forecast Offices in both Little Rock, AR and Tulsa, OK will be down
for approximately four days beginning Friday, March 3, 2017 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

During the outage, radar coverage is available from adjacent radar
sites from KINX (Inola, OK) for eastern Oklahoma/Northwest Arkansas
while the KLZK (Little Rock, AR) overage area for Western Arkansas.

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
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

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:
