National Weather Service Uncovers Error in Posting of Tsunami Advisory
Pacific County has been informed that the National Weather Service website has posted information in error regarding the Tsunami Advisory resulting from a M8.0 earthquake that occurred of the coast of American Samoa. The NWS website http://www.wrh.noaa.gov/pqr/ indicates that the West Coast Alaska Tsunami Warning Center has issued a Tsunami Advisory for the coast of Pacific County. This is an error in geo-coding that cannot be corrected at this time. Based upon the best available forecast information, there WILL NOT be issuing a Tsunami Advisory for the coast of Washington State, British Columbia, or Alaska. A TSUNAMI ADVISORY MEANS THAT A TSUNAMI CAPABLE OF PRODUCING STRONG CURRENTS OR WAVES DANGEROUS TO PERSONS IN OR VERY NEAR THE WATER IS IMMINENT OR EXPECTED. SIGNIFICANT WIDESPREAD INUNDATION IS NOT EXPECTED FOR AREAS UNDER AN ADVISORY. CURRENTS MAY BE HAZARDOUS TO SWIMMERS... BOATS... AND COASTAL STRUCTURES AND MAY CONTINUE FOR SEVERAL HOURS AFTER THE INITIAL WAVE ARRIVAL. Wave heights for CA and OR may be up to 55 cm (appx. 1.8 feet). Projected heights for WA at Neah Bay and Toke Point are forecast to be smaller, around 6 cm (appx. 0.19 ft.) The arrival time for the West Coast is expected to be approximately 6 hours from now around 9 pm PDT and arrival in Hawaii will occur within 2 hours.
