PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE CARIBOU ME
657 AM EDT THU MAR 31 2016

...TSUNAMI PREPAREDNESS WEEK IN MAINE...

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, AS WELL AS IN
THE REMAINDER OF THE COASTAL UNITED STATES.

TODAY`S TOPIC...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.

PLEASE STAYED TUNED-IN THIS WEEK AS WE PROVIDE ADDITIONAL
EDUCATIONAL MATERIAL ON THE TSUNAMI THREAT IN MAINE.
