* 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.

further notice.
