...KHTX 88D Radar Outage Beginning July 17th for Upgrade...

The NWS 88D Doppler weather radar located in Hytop, Alabama will
be down for up to two weeks beginning on the morning of Monday, 
July 17th for technicians to install an important technological 

During the outage, radar coverage is available from nearby radar
sites, including the DOD radar at Columbus AFB and NWS radars for
our forecast offices at Nashville, TN and Birmingham, AL. 

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 shelters. 

The tri-agency Radar Operations Center, which supports the 
radars, estimates that it will take about 10 months in 2016/2017 
to upgrade the signal processor on all 159 operational WSR-88Ds.
