Beginning March 4, 2021,  the KLVX WSR-88D radar operated by the NOAA National Weather
Service in Louisville, KY, will be down for approximately seven days for the replacement of the
generator, fuel tanks, and accompanying components.

This activity is important to support the radar’s operation during periods of commercial power outages, specifically when hazardous
weather is present.  This upgrade to the KLVX radar is expected to be completed by March 10, 2021.


This generator update is the fifth major project of the NEXRAD Service Life Extension Program, a
series of upgrades and replacements that will keep our nation’s radars viable into the 2030’s.
NOAA National Weather Service, the United States Air Force, and the Federal Aviation
Administration are investing $150 million in the seven year program. The first project was the
installation of the new signal processor and the second project was the transmitter
refurbishment. The two remaining projects are the refurbishment of the pedestal and equipment
shelters. The Service Life Extension Program will complete in 2023.

During the downtime, adjacent radars include:

TSDF – Louisville, Kentucky TWDR
TCVG – Covington, Kentucky TWDR
KIND – Indianapolis, Indiana WSR-88D
KOHX – Nashville, Tennessee WSR-88D
KVWX – Evansville, Indiana WSR-88D
KJKL – Jackson, Kentucky WSR-88D
KHPX – Hopkinsville, Kentucky WSR-88D
