The tsunami risk in Everett is mainly concentrated along the waterfront and Snohomish River delta including Jetty Island, marinas, and other low-lying coastal areas. To see modeled inundation and maximum current speed maps, click the links below or visit WA State DNR's tsunami webpage.
In the summer of 2021, two All Hazard Alert and Broadcasting (AHAB) sirens were installed at the Port of Everett to provide alerts to people near them in the event of a tsunami.
The sirens have an audible range of approximately 1 mile, though this varies depending on environmental factors like topography, wind direction, and physical barriers such as trees and buildings. The pole-mounted voice/tone siren is also topped with a blue light for the hard of hearing.
The sirens are not intended to be heard indoors. That’s why it’s important to be signed up for tsunami alerts and to have a NOAA weather radio receiver.
The siren system is tested on the first Monday of every month at noon; the sirens play the Westminster Chimes followed by an audio message in English and Spanish.
The sirens are also tested once a year with the actual tsunami warning wail sound on the third Thursday in October in conjunction with the Great Washington ShakeOut.
If you hear the siren wailing sound outside of the Great Washington ShakeOut, immediately evacuate to high ground away from the waterfront.
