The National Oceanic Atmospheric and Administration (NOAA) and State of California Governor’s Office of Emergency Services (Cal OES) plan to conduct a test of the tsunami warning communications system on Wednesday, March 25 at 10:15 a.m.

NOAA’s National Weather Service (NWS) Offices in Monterey, Oxnard and San Diego will broadcast the “Required Monthly Test.” The test will also be broadcast on the NOAA Weather Radio All Hazards, local television and radio stations.

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.

The test will be canceled if there is excessive seismic activity 24 hours prior to the test.

During Tsunami Preparedness Week (March 22-28), NOAA and emergency managers will be promoting tsunami safety and awareness, and urge coastal residents and visitors to prepare themselves and their families for a tsunami. NOAA’s National Tsunami Warning Center offers complete information, including the current status of tsunami warnings, watches, advisories and frequently asked questions.
