Beginning Friday, March 12, 2020, the KDVN WSR-88D radar operated by the NOAA National Weather Service in the Quad Cities will be down for approximately one week as part of the Service Life Extension Program (SLEP).



During the downtime, adjacent radars include: KDMX (Des Moines, IA), KARX (La Crosse, WI), KMKX (Milwaukee/Sullivan, WI), KLOT (Chicago/Romeoville, IL), KILX (Lincoln, IL), KLSX (St. Louis, MO) and KEAX (Kansas City/Pleasant Hill, MO).  For direct access to any of these surrounding radar sites, go to the following web page:



In this part of the upgrade, the generator, fuel tanks and accompanying components will be replaced. These are important to support the radar's operation during periods of commercial power outages, specifically when hazardous weather is present.

This is one of five major upgrades to the radar as part of SLEP. The first two were the installation of a new signal processor and a transmitter refurbishment, which were completed over the past two years. The last two projects are the refurbishment of the pedestal and equipment shelters. All of this should be completed by 2023.

The KDVN WSR-88D is part of a network of 159 operational Doppler radars.  The Radar Operations Center in Norman, Oklahoma, provides life cycle management and support for all WSR-88Ds.
