Subject: NWS to Issue National Tsunami Warning Center Routine
 Communications Tests for the East and Gulf Coast on
 April 23, 2024

The NWS National Tsunami Warning Center (NTWC) and coastal NWS
Weather
Forecast Offices (WFOs) will perform routine monthly tsunami
communication
tests to ensure end-to-end readiness of NWS dissemination software
and
hardware on Tuesday, April 23, 2024 for East and Gulf Coast states.

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 Codes (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, 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):
