NWS is planning a 3-hour test of the KLGX data transmission capabilities of the new Weather Surveillance Radar-1988, Doppler (WSR-88D) in Grays Harbor County, WA.  The test is planned to occur on or about 9 am to noon (PACIFIC) on Sep 8, 2011. Level 2 and Level 3 data/products will be transmitted to external users during this period. The radar will be operating in standard

The KLGX Dual Polarization modification is scheduled to start September 12, 2011.  The estimated date the modification will be completed and Level 2 and Level 3 data/products will be transmitted to external users is Sep 23.  The addition of Dual Polarization products to the KLGX data transmission will be on or about Sep 27, 2011.
