Subject: National Tsunami Warning Center Routine Communications Tests
for
 the West Coast and Alaska Coast to Take Place on March 31,
2024

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, March 21, 2024.

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.

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
