The Washington Emergency Management Division said residents should expect hours of waves as high as 3 feet. It will also coincide with high tide to create dangerous coastal conditions and flooding.

All coastlines around the world are vulnerable to tsunamis, so it's important to know your community's hazard and evacuation plans in case they're needed.

What is a tsunami and what causes them?
