Officials to test tsunami warning system in Del Norte, Humboldt and Mendocino counties during Tsunami Preparedness Week

NOAA and the California Emergency Management Agency plan to conduct a test of the tsunami warning communications system on March 27 between 11 a.m. and noon Pacific Daylight Time in coastal areas of northern California.

This emergency test will be broadcast on NOAA Weather Radio All Hazards, local television and radio stations in Del Norte, Humboldt, and Mendocino counties. Residents in some communities may hear warning sirens.

Some television systems are programmed to scroll a standard emergency alert text message and in some cases, the message may not contain the word “TEST.”  An audio message will say that the message is only a test, but if the volume is turned down or otherwise unheard, viewers may not realize the message is a test.

To avoid confusion with an actual alert the test will be canceled if there is excessive seismic activity 24 hours prior to the test.  People monitoring the test in coastal areas who do not receive it are asked to inform their local National Weather Service office. The public can provide feedback online at http://www.nws.noaa.gov/test/. The test is a cooperative effort between NOAA, the California Emergency Management Agency, California Broadcasters Association, and local emergency management officials in coastal California.

During National Tsunami Preparedness Week, March 24 -30, emergency managers urge coastal residents to review information on what to do in the event of a tsunami. NOAA’s West Coast and Alaska Tsunami Warning Center Web site offers complete information, including the current status of tsunami watches, warnings and advisories.
