If you are in an advisory area – move off the beach and out of harbors and marinas. Widespread inundation of land is not expected for advisory areas. Be alert to instructions from your local emergency officials. Do not go to the coast to observe the tsunami. Do not return to the coast until local emergency officials indicate it is safe to do so.Next update and additional information: This message will be updated in 60 minutes or sooner if the situation warrants. The tsunami message will remain in effect until further notice. Refer to the internet sitentwc.arh.noaa.gov for more information.
  • A tsunami advisory is issued due to the threat of a potential tsunami which may produce strong currents or waves dangerous to those in or near the water. Coastal regions historically prone to damage due to strong currents induced by tsunamis are at the greatest risk. The threat may continue for several hours after the arrival of the initial wave, but significant widespread inundation is not expected for areas under an advisory. Appropriate actions to be taken by local officials may include closing beaches, evacuating harbors and marinas, and the repositioning of ships to deep waters when there is time to safely do so. Advisories are normally updated to continue the advisory, expand/contract affected areas, upgrade to a warning, or cancel the advisory.
