* UPDATES...
  There have been no significant changes since the last
  statement.

* LOCAL IMPACTS...Dangerous currents and fast tidal swings will
  persist through the morning due to impacts from an ongoing tsunami
  event. These conditions are hazardous to swimmers, boats, and
  coastal structures. Widespread inundation is NOT expected.
  However, damage at the harbors is possible. Surging water in and
  out of harbors and changing water levels can cause boats and docks
  to detach from structures.

* RECOMMENDED ACTIONS...If you are located in this coastal area,
  move off the beach and out of harbors and marinas. Do not go to
  the coast to watch the tsunami. Be alert to instructions from your
  local emergency officials. Tsunamis often arrive as a series of
  waves or surges which could be dangerous for many hours after the
  first wave arrival. The first tsunami wave or surge may not be the
  highest in the series.

* FORECAST TSUNAMI DURATION...The Advisory remains in effect until
  further notice.
