PUBLIC INFORMATION STATEMENT 
NATIONAL WEATHER SERVICE GRAY ME
702 AM EST THU NOV 06 2014


THE NATIONAL WEATHER SERVICE OFFICES THAT SERVE NEW ENGLAND HAVE 
DECLARED THE WEEK OF NOVEMBER 3RD THROUGH 7TH, WINTER WEATHER 
AWARENESS WEEK.  IN CONJUNCTION WITH WINTER WEATHER AWARENESS 
WEEK, THE NATIONAL WEATHER SERVICE OFFICE IN GRAY WILL BE ISSUING 
PUBLIC INFORMATION STATEMENTS CONCERNING MANY ASPECTS OF WINTER 
WEATHER AND WINTER WEATHER PREPAREDNESS.  THIS IS THE FOURTH IN 
A SERIES OF FIVE PUBLIC INFORMATION STATEMENTS TO BE ISSUED THIS 
WEEK.


...HIGH WIND, COASTAL FLOODING AND EROSION, AND DENSE FOG 
THREATS...

IN ADDITION TO SNOW, SLEET, FREEZING RAIN AND RAIN, WINTER STORMS 
BRING THE THREAT OF HIGH WINDS AND COASTAL FLOODING TO NORTHERN 
NEW ENGLAND.  DENSE FOG, CAUSED BY WARM AIR MOVING OVER COLD 
SNOW-COVERED GROUND, IS ALSO A FREQUENT HAZARD IN NORTHERN NEW 
ENGLAND DURING THE WINTER AND EARLY SPRING.


...HIGH WINDS...

HIGH WINDS CAN OCCUR BEFORE, DURING, AND AFTER MAJOR WINTER STORMS 
AND CAN MAKE DRIVING DIFFICULT AND DANGEROUS, ESPECIALLY IF YOU 
DRIVE A HIGH-PROFILE VEHICLE.  IF YOUR VEHICLE STARTS TO SWERVE 
DUE TO THE WIND, SLOW DOWN.  HIGH WINDS CAN CAUSE SNOW TO BLOW AND 
DRIFT, REDUCING VISIBILITIES AND CAUSING SLIPPERY CONDITIONS ON 
THE ROADWAYS.  ALSO, HIGH WINDS BRING INCREASED DANGER FROM 
FALLING TREES, WHICH CAN LEAD TO POWER OUTAGES.

TO ALERT THE PUBLIC TO POTENTIALLY DANGEROUS WIND EVENTS, THE 
NATIONAL WEATHER SERVICE ISSUES HIGH WIND WATCHES, HIGH WIND 
WARNINGS, AND WIND ADVISORIES.  THESE ALERTS ARE BASED ON THE 
FOLLOWING CRITERIA.

   HIGH WIND WATCH -   SUSTAINED WINDS OF 40 MPH OR GREATER OR
                       FREQUENT GUSTS TO 58 MPH OR GREATER ARE
                       POSSIBLE WITHIN THE NEXT 24 TO 48 HOURS.

   HIGH WIND WARNING - SUSTAINED WINDS OF 40 MPH OR GREATER OR
                       FREQUENT GUSTS TO 58 MPH OR GREATER ARE
                       LIKELY WITHIN THE NEXT 24.

   WIND ADVISORY -     SUSTAINED WINDS OF 31 TO 39 MPH OR
                       FREQUENT GUSTS TO BETWEEN 46 AND 57 MPH
                       ARE LIKELY WITHIN THE NEXT 24 HOURS.

IN ADDITION, WINTER WEATHER ADVISORIES ARE ISSUED WHEN BLOWING AND 
DRIFTING SNOW REDUCES VISIBILITIES TO 1/4 MILE OR LESS CREATING 
A SIGNIFICANT HAZARD ON THE ROADWAYS.


...COASTAL FLOODING AND BEACH EROSION...

COASTAL FLOODING CAN PRECEDE OR ACCOMPANY MAJOR WINTER STORMS.  
STRONG SOUTH, SOUTHEAST, EAST, AND NORTHEAST WINDS CAN CAUSE WATER 
TO PILE UP ALONG THE MAINE AND NEW HAMPSHIRE COASTLINES CAUSING 
TIDE LEVELS TO RISE ABOVE NORMAL.  IN ADDITION TO ABNORMALLY HIGH 
TIDES, LARGE WAVES ASSOCIATED WITH A STORM CAN CAUSE SUBSTANTIAL 
BEACH EROSION ALONG THE COASTLINE.

TO ALERT THE PUBLIC TO THE POTENTIAL FOR COASTAL FLOODING, THE 
NATIONAL WEATHER SERVICE ISSUES COASTAL FLOOD WATCHES AND COASTAL 
FLOOD WARNINGS.  IN DETERMINING THE POTENTIAL THREAT FROM A 
PARTICULAR STORM, THE NATIONAL WEATHER SERVICE CONSIDERS THE 
TIMING AND HEIGHT OF THE NORMAL TIDES, THE TIMING OF THE STORM, 
AND THE EXPECTED STORM SURGE THAT WILL ACCOMPANY THE STORM.

   COASTAL FLOOD WATCH - COASTAL FLOODING POSSIBLE WITHIN THE
                         NEXT 24 TO 48 HOURS.

   COASTAL FLOOD WARNING - COASTAL FLOODING LIKELY WITHIN THE
                           NEXT 24 HOURS.

NOTE THAT BEACH EROSION CAN OCCUR FROM LARGE STORM-GENERATED WAVES 
EVEN THOUGH THE TIDE LEVELS MAY NOT BE ABOVE FLOOD LEVELS.  IN 
THESE CASES, THE LIKELIHOOD AND SEVERITY OF ANY BEACH EROSION IS 
ADDRESSED IN THE PUBLIC FORECAST PRODUCT.


...DENSE FOG... 

DURING LATE WINTER AND EARLY SPRING, WARM AIR MOVING NORTHWARD FROM 
AREAS TO OUR SOUTH, OFTEN ENCOUNTERS THE COLD SNOW-COVERED GROUND 
IN NORTHERN NEW ENGLAND.  THIS COMBINATION OF WARM AIR MOVING OVER 
A COLD SURFACE OFTEN RESULTS IN THE FORMATION OF DENSE FOG.  
PRECIPITATION WILL ALSO ENHANCE THE LIKELIHOOD OF DENSE FOG 
FORMATION.  MOTORISTS SHOULD BE EXTREMELY CAREFUL WHEN DRIVING IN 
THESE CONDITIONS.  VISIBILITIES MAY CHANGE FROM GOOD TO NEAR-ZERO 
VISIBILITY IN A MATTER OF FEET.  IN SOME CASES, THE FOG MAY BE SO 
DENSE THAT IT MAY BE DIFFICULT TO EVEN SEE THE EDGE OF THE ROAD.  
IN ADDITION, DENSE FOG MAY HIDE OTHER HAZARDS SUCH AS DEER OR MOOSE 
IN THE ROADWAY, STOPPED MOTORISTS, OR FLOODING.  BE ESPECIALLY 
CAREFUL AT NIGHT.  

TO ALERT THE PUBLIC TO THESE DANGEROUS CONDITIONS, THE NATIONAL 
WEATHER SERVICE ISSUES DENSE FOG ADVISORIES.  DENSE FOG 
ADVISORIES ARE ISSUED FOR CASES WHEN WIDESPREAD DENSE FOG CREATES 
NEAR-ZERO VISIBILITY OVER A LARGE AREA.

PREPAREDNESS TIP FOR THE DAY:

ONE OF THE GREATEST DANGERS DURING HIGH WIND EVENTS IS FROM FALLING 
TREES AND/OR TREE LIMBS.  TO REDUCE THE DANGER FROM HIGH WINDS, 
CUT DOWN ANY DEAD OR DISEASED TREES AND PRUNE ANY TREE LIMBS THAT 
COULD POTENTIALLY FALL ON SOMEONE OR SOMETHING BEFORE THEY FALL.


QUESTION OF THE DAY:

DO HURRICANES OR WINTER STORMS CAUSE THE HIGHEST STORM SURGES ALONG 
THE MAINE AND NEW HAMPSHIRE COASTLINES?

   ANSWER: BOTH HURRICANES AND WINTER/SPRING STORMS CAN CAUSE 
   SIGNIFICANT STORM SURGES ALONG THE MAINE AND NEW 
   HAMPSHIRE COASTLINES.  HOWEVER, BECAUSE THE COAST GETS 
   HIT BY MANY MORE WINTER STORMS THAN HURRICANES, THE 
   GREATEST SURGES IN THE PAST HAVE COME FROM WINTER OR 
   SPRING STORMS.  IN FACT, OF THE TOP TEN SURGES RECORDED 
   IN PORTLAND, NINE WERE FROM WINTER/SPRING STORMS WHILE 
   ONLY ONE WAS FROM A HURRICANE (HURRICANE CAROL, 1954, 
   TIE FOR 8TH HIGHEST SURGE).  THE GREATEST SURGE REPORTED 
   IN PORTLAND WAS 4.3 FEET ON MARCH 3, 1947.  THIS COMPARES 
   WITH THE 3.3 FT SURGE OBSERVED WITH HURRICANE CAROL.

   ON FEBRUARY 2, 1976, AN INTENSE WINTER STORM CAUSED A 
   STORM SURGE ALONG THE MID AND DOWNEAST COAST OF MAINE 
   FROM BRUNSWICK TO EASTPORT.  AFTER REACHING THE COAST, 
   THE SURGE OF WATER FUNNELED UP THE PENOBSCOT RIVER 
   CAUSING A SURGE OF OVER 10 FT IN THE CITY OF BANGOR.  
   REPORTEDLY, AT AROUND 11 AM, THE WATER LEVEL IN THE CITY 
   ROSE MORE THAN 12 FT IN JUST 15 MINUTES, SUBMERGING 
   APPROXIMATELY 200 VEHICLES.  MANY PEOPLE WERE TRAPPED 
   IN BUILDINGS BY THE FRIGID WATER, AND SOME HAD TO BE 
   RESCUED QUICKLY FROM THE TOPS OF THEIR CARS.

IN PUBLIC INFORMATION STATEMENTS DURING WINTER WEATHER AWARENESS 
WEEK.
