Subject: National Tsunami Warning Center Routine Communications

Tests for the West Coast and Alaska Coast to Take Place on July

16, 2026



The NWS National Tsunami Warning Center (NTWC) and coastal NWS

Weather Forecast Offices (WFOs) will perform a routine monthly

tsunami communication test to ensure end-to-end readiness of NWS

dissemination software and hardware on Thursday, July 16, 2026.



The intended recipients of these communication tests include

designated national focal points, state/territorial warning

points, coastal WFOs, U.S. Coast Guard and critical military

dissemination points.



These tests are not intended for the Public, nor should they be

transmitted by third-party services or apps to the public.  They

will not appear on tsunami.gov.



Valid Time Event Code (VTEC) for the test messages will start

with the /T fixed identifier (versus /O for operational

messages).  To provide additional assurance that a test message

is not inadvertently distributed as an actual

Warning/Advisory/Watch product, the Event Tracking Numbers

(ETNs) for the test messages will begin with 9 as the leading

digit of the four character code.



The text products affected by routine monthly tsunami

communication testing are the national tsunami products issued

under the following Advanced Weather Interactive Processing

System (AWIPS) Product Identifiers (PIL) and World

Meteorological Organization (WMO) Identifiers (IDs):
