Residents must register and opt-in to receive emergency notifications to their cell phones and other devices.

This is the primary system which is used to communicate with the public during times of emergency- it is vital residents register to ensure they get important time sensitive information.

The October 18th Alert and Notification test will send a test notification to all registered community members county-wide via their preferred communication method (text message, voice phone call, or email) and to most land lines. This message will clearly state that the notification is only a test and not a real emergency. Community members are urged register for the Alert and Notification System prior to the October 18th test date to participate and ensure they can receive the county’s emergency notifications.

Additionally, on October 18th between 11:00 am and 12:00 pm (noon) the National Weather Service (NWS) office in Eureka will be conducting a Tsunami Warning Communications Test in Mendocino, Humboldt and Del Norte Counties.

If you are listening to the radio, you may hear alerting tones followed by a voice announcing that the test is occurring. If you have a NOAA weather radio with the Public Alert feature, the radio will automatically turn on and you will hear the same message as broadcast on radios. In some areas, you may also hear the sounding of a tsunami siren, or an airplane testing its public address system.  The tsunami sirens in Noyo Harbor, Pudding Creek, and Point Arena Cove are planned to be activated and will sound for approximately one to three minutes.
