While the July 21st tsunami advisory for Valdez & Prince William Sound was cancelled without incident, it is a good reminder for our community to refresh tsunami preparedness knowledge, including knowing what different tsunami alerts mean and where to go if you must evacuate.

Tsunami Warnings

There are two ways you may be warned a tsunami is coming: an official tsunami warning and a natural tsunami warning. Both are equally important. You may not get both.

Official tsunami warnings may include hearing our local tsunami sirens, receiving a NWS/NOAA alert on your phone, or hearing a broadcast on marine radio.

Natural tsunami warnings include strong or long earthquakes, a loud roar (like a train or an airplane) from the ocean, and unusual ocean behavior. The ocean could look like a fast rising flood or a wall of water. Or, it could recede suddenly like a very low, low tide. If you experience any of these warnings, even just one, a tsunami could be coming.

The most important thing to remember if you observe a tsunami warning - especially if you hear our local tsunami sirens - is to stop what you are doing and move quickly to a safe location. Local evacuation routes are outlined in the map below. Make sure to take pets and crucial items like medications and your emergency kit which you may not be able to access later.
