By Jaime Yarbrough The annual Tsunami Warning Communications Test in Del Norte, Humboldt, and Mendocino counties will be conducted on Wednesday, March 24th between 11 am and noon. The test will interrupt TV and radio broadcasts and turn on tsunami sirens in some areas. Additionally, local jurisdictions may test their reverse calling systems and the Civil Air Patrol will conduct a test of their airplane mounted broadcast system (weather depending). Be ready and remember, it’s only a test!#NWCATsunamiTest2021
