Tsunami Warning Test on Wednesday


The annual Tsunami Warning Communications Test takes place Wednesday between 11 a.m. and noon, with sirens, a Civil Air Patrol flyover, alerts and notifications via NOAA weather radio as well as local TV and radio.

An annual coordinated effort between between the National Weather Service, local tribal governments, Caltrans District 1, the Civil Air Patrol and the emergency services offices of the state as well as the counties of Humboldt, Del Norte and Mendocino, the test is designed to check the workings of the electronic communications system used when a tsunami warning is issued for the region.

The California Geological Survey recently issued updated Tsunami Hazard maps for the counties of Del Norte, Humboldt and Mendocino, which can be found here.

Read the Del Norte County OES release below:
The County of Del Norte Office of Emergency Services, in collaboration with the National Weather Service and California Governor’s Office of Emergency Services, and along with Humboldt and Mendocino counties, will participate in a test of the tsunami warning communication system on March 24, 2021. Citizens who have a home, business, or school address within the tsunami hazard area and who are registered for Community Alerts can expect to receive a notification at approximately 10:00am. Additional notifications will be delivered between 11:00am – 12:00pm via outdoor sirens, NOAA weather radio, local TV and radio, and civil air patrol flyover. This annual test is an important part of local and regional emergency preparedness. Tests are routinely conducted to ensure that notification systems perform as expected. If any failures are identified emergency officials will then work to address those failures. These tests also serve as a reminder to the public to review their own personal preparedness plans. Citizens are encouraged to take the following personal preparedness steps this week in advance of the test:
