Annual Tsunami Warning Communications Test This Wednesday

This is a press release from the National Weather Service:

WHEN: Wednesday, March 29, 2023, between 11:00 a.m. & 12:00 Noon WHERE: Del Norte, Humboldt, and Mendocino counties. 

HOW: Interruptions of TV* and Radio Stations, and activation of NOAA Weather Radios and Outdoor Sirens. 

*Not all Cable and Satellite TV Stations may be able to participate
WHY: To test the Tsunami Warning System to ensure it works properly 

during a real tsunami emergency. 

HOW THIS TEST WILL AFFECT YOU: 

If you are watching television between 11:00 a.m. and 12:00 Noon on Wednesday morning, expect to see a crawler at the bottom of the screen indicating that a tsunami warning has been issued, and hear a voice indicating that it is only a test. If you don’t hear the TV audio, please remember that this is only a test. If you are listening to the radio, you will hear alerting tones followed by a voice announcing that the test is occurring. If you have a NOAA weather radio with the Public Alert feature, the radio will automatically turn on and you will hear the same message as broadcast on radios. In some areas, you may also hear the sounding of a tsunami siren, an airplane testing its public address system (possibly as late as 1 pm), or receive other communications tests in some local jurisdictions. The Wireless Emergency Alert (WEA) system will NOT be activated for this test.
