The National Weather Service Pacific Tsunami Warning Center has issued a tsunami warning for Hawaii and a tsunami advisory for the West Coast of the United States.

A NWS spokesman on CNN says it is estimated the tsunami waves will be 10 to 15 feet high when they hit Hawaii. The tsunmi waves could last up to six hours.

Recent buoy reports of wave heights vary from 5 to 16 feet.

SNIP

EVALUATION

A TSUNAMI HAS BEEN GENERATED THAT COULD CAUSE DAMAGE ALONG COASTLINES OF ALL ISLANDS IN THE STATE OF HAWAII. URGENT ACTION SHOULD BE TAKEN TO PROTECT LIVES AND PROPERTY.

A TSUNAMI IS A SERIES OF LONG OCEAN WAVES. EACH INDIVIDUAL WAVE CREST CAN LAST 5 TO 15 MINUTES OR MORE AND EXTENSIVELY FLOOD COASTAL AREAS. THE DANGER CAN CONTINUE FOR MANY HOURS AFTER THE INITIAL WAVE AS SUBSEQUENT WAVES ARRIVE. TSUNAMI WAVE HEIGHTS CANNOT BE PREDICTED AND THE FIRST WAVE MAY NOT BE THE LARGEST. TSUNAMI WAVES EFFICIENTLY WRAP AROUND ISLANDS. ALL SHORES ARE AT RISK NO MATTER WHICH DIRECTION THEY FACE. THE TROUGH OF A TSUNAMI WAVE MAY TEMPORARILY EXPOSE THE SEAFLOOR BUT THE AREA WILL QUICKLY FLOOD AGAIN. EXTREMELY STRONG AND UNUSUAL NEARSHORE CURRENTS CAN ACCOMPANY A TSUNAMI. DEBRIS PICKED UP AND CARRIED BY A TSUNAMI AMPLIFIES ITS DESTRUCTIVE POWER. SIMULTANEOUS HIGH TIDES OR HIGH SURF CAN SIGNIFICANTLY INCREASE THE TSUNAMI HAZARD.

THE ESTIMATED ARRIVAL TIME IN HAWAII OF THE FIRST TSUNAMI WAVE IS

1119 AM HST SAT 27 FEB 2010

Here is a local report on the West Coast tsunami advisory:

A tsunami advisory has been issued for the California coast, including Del Norte County, following a massive 8.8-magnitude earthquake that struck off the central coast of Chile at 10:34 p.m. PST Friday.

The forecasted arrival time for Crescent City is 1:46 p.m. PST Saturday, however tsunamis can be dangerous for many hours after arrival, and the initial wave is not necessarily the largest, the West Coast and Alaska Tsunami Warning Center says.

THIS BULLETIN APPLIES TO AREAS WITHIN AND BORDERING THE PACIFIC OCEAN AND ADJACENT SEAS...EXCEPT ALASKA...BRITISH COLUMBIA... WASHINGTON...OREGON AND CALIFORNIA.
