Officials to Test Tsunami Warning System in Del Norte, Humboldt and Mendocino Counties During Tsunami Preparedness Week

NOAA and the California Governor’s Office of Emergency Services (Cal OES) plan to conduct a test of the tsunami warning communications system on Wednesday, March 28 between 11 a.m. and noon PDT 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.
This test is a cooperative effort between NOAA, Cal OES, California Broadcasters Association, and local emergency management officials in coastal areas of Northern California. During California’s Tsunami Preparedness Week, March 26-30, NOAA and emergency managers promote tsunami safety and awareness and urge coastal residents and visitors to prepare themselves and their families for a tsunami.
Everyone, everywhere should know how to be prepared for tsunamis and what to do to be safe. This is true for people who live or work near the ocean, and also for anyone who may visit someday.
