Evaluation Advisory

Sea level readings indicate a TSUNAMI was generated
Observations and models indicate that no more TSUNAMI waves are expected
When no major waves are observed for two hours after the estimated time of arrival or damaging waves have not occurred for at least two hours then local authorities can assume the threat is passed
Danger to boats and coastal structures can continue for several hours due to the continuing sea level changes and rapid currents
As local conditions can cause a wide variation in TSUNAMI wave action the all clear determination must be made by local authorities
