Press release from the County of Mendocino:

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 their 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.

Please help us by providing any feedback regarding this test by emailing: [email protected]

When you hear or see the warning test on March 29 between 11:00 a.m. & 12:00 Noon:

  • You do NOT need to take any action
  • Do NOT call 911 or local authorities
  • Do NOT evacuate your home or business

THIS IS ONLY A TEST!!

When we gonna switch it up from atmospheric river to atmospheric tsunami, crack me up. I see over 600 inches of snow in Tahoe this year so far, 200 inches of base this weekend. Definitely still in a drought.

For you yes. After all you are the self-proclaimed “comedian”.
What are we to believe?
Are you 70 years old?
Or are you “Not a boomer”? Inquiring minds want to know.
Crack us all up 🤣

Yup. There will be two streams of people. Smaller stream running for the hills. Larger one people will be coming down to take selfies with the tsunami.

What’s the power source for these sirens? Are they battery-powered or are they plugged in to the power grid? If it’s the latter, will they work if power is knocked out in a large earthquake?

They are ran off a hand crank driven by a water wheel, as the tsunami rips by the water wheel,the siren sounds. Fail safe and no false alarms.

In a large triple junction mega quake, nothing will be working afterward, battery or electric. Sorry to burst your bubble. Your Prius won’t work either because you will not be able to charge it because the power is out. Catch 22 huh. Yep. Exactly why EV cars are a total joke besides causing children in the Congo mining cobalt to die young. So much for the Democrats supposed sympathy for the plight of the worlds poor black children. Pro tip, they don’t give a dam as long as they can keep their cell phone and eat sushi weekly.
