A reminder, the National Weather Service will conduct a tsunami warning communications test between 11 am and noon today in Mendocino, Humboldt, and Del Norte Counties. The EAS system will broadcast alerts on local tv and radio stations and on NOAA weather radios as well as local tsunami warning sirens. The Civil Air Patrol will also fly the coastline testing their public address system. The Wireless Emergency Alert system will NOT be activated for this test.
