...NWS Raleigh WSR-88D Radar (KRAX) Scheduled for Upgrade
Beginning Tomorrow, Monday, July 24...

The National Weather Service Raleigh WSR-88D Doppler weather
radar, KRAX, located in Clayton, NC, will be down for
approximately four days beginning Monday, July 24, 2017, for
technicians to install an important technological upgrade.

During the outage, radar coverage should be available from
adjacent NWS radar sites, including Blacksburg, VA (KFTX);
Wakefield, VA (KAKQ); Newport/Morehead City, NC (KMHX);
Wilmington, NC (KLTX); Columbia, SC (KCAE); Greenville-
Spartanburg, SC (KGSP) as well as the Federal Aviation
Administration Terminal Doppler Weather Radar in Raleigh,

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 the Service
Life Extension Project (SLEP), planned over 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
operationally 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.
