The National Weather Service in Seattle will participate in the EAS portion of this test, relaying the National Periodic Test (NPT) message across the NOAA Weather Radio network in Western Washington. Please note that NOAA Weather Radios with Specific Area Message Encoding (SAME) receiving capabilities that are set up to alert for NPT messages will alarm for this test as will tone-alert radios.
