PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE GRAY ME
700 AM EST THU MAR 31 2016

THE NATIONAL WEATHER SERVICE AND THE NATIONAL OCEANIC AND
ATMOSPHERIC ADMINISTRATION HAVE DECLARED THE WEEK OF MARCH 28TH
THROUGH APRIL 1ST TSUNAMI PREPAREDNESS WEEK IN MAINE AND NEW
HAMPSHIRE, AS WELL AS IN THE REMAINDER OF THE COASTAL UNITED
STATES.

...STAYING SAFE WHEN A TSUNAMI THREATENS...

FORTUNATELY FOR NORTHERN NEW ENGLAND, THE GEORGES BANK SHELTERS
THE COAST FROM A MAJOR TSUNAMI THREAT.  HOWEVER, SMALL BUT
DANGEROUS, DAMAGING, AND POTENTIALLY DEADLY TSUNAMI WAVES ARE
POSSIBLE.  IN THE GULF OF MAINE, THE GREATEST TSUNAMI THREAT
WOULD BE FROM THE RAPID AND CHAOTIC CHANGES IN THE WATER LEVELS,
AND THE STRONG CURRENTS THOSE CHANGES WOULD GENERATE.  SOME
INUNDATION OF LAND AREAS IS POSSIBLE AT THE TIME OF HIGH TIDE;
HOWEVER, THE GREATEST THREAT FROM A TSUNAMI IS DUE TO THE
POWERFUL FORCES GENERATED BY THE RAPIDLY MOVING WATER.

TSUNAMI WATCHES, WARNINGS, AND ADVISORIES...

THE TSUNAMI WARNING CENTER IN PALMER, ALASKA, ISSUES TSUNAMI
WATCHES, WARNINGS, AND ADVISORIES FOR THE EAST COAST.  THE
CENTER MONITORS SEISMIC ACTIVITY THROUGHOUT THE WORLD AND
DETERMINES THE LIKELIHOOD OF TSUNAMIS BASED ON THAT ACTIVITY.

A TSUNAMI WATCH IS ISSUED BASED ON SEISMIC INFORMATION WHEN A
TSUNAMI IS POSSIBLE FOR A PARTICULAR LOCATION.  THE WATCH
PROVIDES ADVANCE NOTIFICATION TO AREAS THAT POSSIBLY COULD BE
IMPACTED BY A DESTRUCTIVE TSUNAMI.  AS MORE INFORMATION BECOMES
AVAILABLE, THE WATCH MAY BE CHANGED TO EITHER A WARNING OR
ADVISORY, OR DROPPED COMPLETELY.  WHEN A WATCH IS ISSUED, IT IS
IMPORTANT TO MONITOR THE ONGOING SITUATION IN CASE A WARNING OR
ADVISORY IS ISSUED.  DURING A WATCH, THE TSUNAMI WARNING CENTER
WILL ISSUE UPDATED INFORMATION AT LEAST EVERY HOUR.

A TSUNAMI WARNING IS ISSUED WHEN THERE IS AN IMMINENT THREAT OF
A TSUNAMI FROM A LARGE UNDERSEA EARTHQUAKE OR UPON CONFIRMATION
THAT A DESTRUCTIVE TSUNAMI WAVE HAS DEVELOPED.  TSUNAMI WARNINGS
ADVISE PEOPLE OF THE APPROPRIATE ACTIONS TO TAKE IN RESPONSE TO
THE TSUNAMI THREAT.  SUCH ACTIONS MIGHT INCLUDE THE EVACUATION
OF LOW-LYING COASTAL AREAS AND THE RECOMMENDATION TO MOVE BOATS
OR SHIPS OUT OF HARBOR TO DEEPER WATERS.

A TSUNAMI ADVISORY IS ISSUED TO INDICATE THAT A TSUNAMI IS NOT
EXPECTED TO PRODUCE SIGNIFICANT WIDESPREAD INUNDATION OF LAND
AREAS, BUT DANGEROUS AND POWERFUL CURRENTS CAN BE EXPECTED TO
DEVELOP ALONG THE COAST.  FOR THOSE IN AN ADVISORY AREA, THE
BEST ADVICE IS TO GET OFF THE BEACHES AND MOVE AWAY FROM THE
WATER EDGE TO HIGHER GROUND.

IN ADDITION TO WATCHES, WARNINGS, AND ADVISORIES, THE TSUNAMI
WARNING CENTER ISSUES INFORMATION STATEMENTS TO KEEP THE PUBLIC
INFORMED OF SEISMIC SITUATIONS WHEN NO WATCH, WARNING, OR
ADVISORY HAS BEEN ISSUED BY THE CENTER.

DURING A TSUNAMI EVENT AFFECTING THE GULF OF MAINE, THE NATIONAL
WEATHER SERVICES OFFICES IN GRAY AND CARIBOU WILL ISSUE SPECIAL
WEATHER STATEMENTS PROVIDING UPDATED INFORMATION ON THE EVENT
AND ITS IMPACT ALONG THE NORTHERN NEW ENGLAND COAST.

STAYING SAFE IN THE GULF OF MAINE...

THE GREATEST THREAT TO THOSE IN THE GULF OF MAINE COMES FROM THE
STRONG CURRENTS THAT A TSUNAMI WOULD GENERATE ALONG THE COAST
AND IN THE MANY CHANNELS AND BAYS.  FOR MOST TSUNAMIS IN THE
GULF OF MAINE, LITTLE, IF ANY, WARNING SHOULD BE EXPECTED.  IF
WATER LEVELS UNEXPECTEDLY START TO RECEDE OR INCREASE, OR IF
STRONG CURRENTS UNEXPECTEDLY START TO DEVELOP, THE BEST ADVICE
IS TO IMMEDIATELY GET OFF BEACHES AND MOVE AWAY FROM THE WATER`S
EDGE TO HIGHER GROUND.  DAMAGE TO BOATS, SHIPS, AND DOCKS MAY
OCCUR, BUT PERSONAL SAFETY IS MORE IMPORTANT THAN DAMAGE.

IF A DISTANT EVENT SUCH AS AN EARTHQUAKE IN THE PUERTO RICAN
TRENCH IS FORECAST TO PRODUCE A TSUNAMI IN THE GULF OF MAINE,
THERE MAY BE TIME TO TAKE ACTION TO LIMIT THE AMOUNT OF DAMAGE
TO PROPERTY.  SHIP AND BOAT OWNERS MAY WANT TO MOVE THEIR
VESSELS OUT OF HARBORS AND CHANNELS TO DEEP WATERS OFF THE COAST
FOR SAFETY.  BE SURE TO HAVE AN ADEQUATE SUPPLY OF FUEL, AS
STRONG CURRENTS AND DAMAGE TO THE HARBOR MAY REQUIRE EXTRA FUEL
CONSUMPTION.  SMALLER BOATS CAN BE HAULED IN FROM THE WATER
UNTIL THE TSUNAMI THREAT HAS PASSED.  HOWEVER, ONCE THE TSUNAMI
WAVES REACH THE GULF OF MAINE, YOU SHOULD KEEP YOUR DISTANCE
FROM THE WATER`S EDGE.  IT IS IMPORTANT TO REMEMBER THAT DURING
A TSUNAMI EVENT IN THE GULF OF MAINE, WATER LEVELS WILL
FLUCTUATE RAPIDLY AND CHAOTICALLY AND SOME LOCALIZED AREAS WILL
SEE RELATIVELY LARGE SURGES COMPARED TO OTHER AREAS.  BE SURE TO
REMAIN AWAY FROM THE WATER`S EDGE UNTIL EMERGENCY OFFICIALS OR
THE NATIONAL WEATHER SERVICE INDICATE THAT THE DANGEROUS
CONDITIONS HAVE SUBSIDED.
