SAN DIEGO - NOAA and the California Emergency Management Agency said they plan to conduct a test of the tsunami warning communications system Wednesday at approximately 10:15 a.m. in coastal areas of southern California.
NOAA’s National Weather Service Offices in San Diego will broadcast the "Required Monthly Test." The test will also be broadcast on NOAA Weather Radio, 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 is a cooperative effort between NOAA, the California Emergency Management Agency, California Broadcasters Association, and local emergency management officials in coastal California.
