MENDOCINO Co, CA, 3/27/23 — If you receive a tsunami warning between 11 a.m. and noon on Wednesday, March 29, don’t rush to evacuate! The National Weather Service (NWS) is testing its Emergency Alerting System (EAS) to ensure communications work properly in Mendocino, Humboldt, and Del Norte counties in the event of an actual tsunami.
The exercise will include interruptions on TV and radio stations, activation of NOAA weather radios, and tsunami sirens. The Civil Air Patrol will also fly the coastline testing its public address system.
The full details from a news release below, as well as advice on tsunami preparations:
When: The National Weather Service will be conducting a communications exercise on March 29, 2023, between 11:00 AM and 12:00 Noon.
Where: Mendocino, Humboldt, and Del Norte counties.
How: The exercise will be testing the Emergency Alerting System (EAS) which will have interruptions on TV and Radio Stations, and activation of NOAA Weather Radios, and Tsunami Sirens. The Civil Air Patrol will also fly the coastline testing its public address system.
Why: This exercise is designed to test the Tsunami Warning System to ensure that it works properly during a real tsunami event.
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, or receive other communication tests in some local jurisdictions. The Wireless Emergency Alert (WEA) system will NOT be activated for this test.
