OXNARD (CBSLA.com) — The city of Oxnard will take part in a test of the tsunami warning communications system, authorities announced Tuesday.

The test – which will also include Monterey and San Diego – will be conducted at 10:15 a.m. Wednesday by the National
Oceanic and Atmospheric Administration and the State of California Governor’s Office of Emergency Services, said Ken Kondo of the Los Angeles County Office of Emergency Management.

NOAA’s National Weather Service offices will also broadcast the test on NOAA Weather Radio All Hazards, local television and radio stations.

Some TV stations, however, are programmed to scroll a standard emergency alert text message which may not contain the word “test” in some cases, Kondo cautioned.

While an audio message will announce that the message is only a test, viewers may not realize it is a test if the volume is turned down or otherwise unheard, Kondo said.

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

It’s all part of Tsunami Preparedness Week, which Gov. Jerry Brown officially announced Monday and continues through Friday.
