Subject: NWS to Issue National Tsunami Warning Center Routine
Communications Tests for the East and Gulf Coast on June 25,
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, June 25,
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 (PILs) and World
Meteorological Organization (WMO) Identifiers (IDs):
