The Tsunami Advisory is canceled for the coastal areas from Alamitos Bay, California (20 miles SE of L.A.) to the Oregon-California border.
Damaging tsunamis are no longer expected to impact the U.S. west coast states, Alaska, and British Columbia. As local conditions can cause a wide variation in tsunami impact, the all clear determinations must be made by local authorities.
Tsunami amplitudes have dropped below dangerous levels at most locations along the U.S. west coast, Alaska and Canada. Sea level conditions still vary greatly from location to location along the coast. Decisions relating to reoccupation of coastal zones must be made by local authorities.
See the advisory for a rundown on maximum surge heights measured along the coast. The highest on the list appears to be 8.7 feet at Point Arena, on the Mendocino County coast, followed by 8.2 feet at Crescent City (Del Norte County) and San Luis Obispo.
