PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE GRAY ME
840 AM EST TUE NOV 04 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 SECOND IN A SERIES
OF FIVE PUBLIC INFORMATION STATEMENTS TO BE ISSUED THIS WEEK.


...WATCH...WARNING...AND ADVISORY CRITERIA FOR WINTER STORMS...

THE NATIONAL WEATHER SERVICE ISSUES WATCHES, WARNINGS, AND
ADVISORIES TO ALERT THE PUBLIC TO POTENTIALLY DANGEROUS WINTER
WEATHER EVENTS OR SITUATIONS.  WHILE THE EXACT CRITERIA USED TO
TRIGGER THESE WATCHES, WARNINGS, AND ADVISORIES VARIES THROUGHOUT
THE UNITED STATES, THE FOLLOWING CRITERIA ARE USED IN MAINE AND NEW
HAMPSHIRE.  NOTE THAT A WATCH IS ISSUED TO ALERT THE PUBLIC THAT
DANGEROUS WINTER CONDITIONS ARE POSSIBLE WITHIN THE WATCHED AREA,
GENERALLY WITHIN THE NEXT 24 TO 60 HOURS.  A WARNING IS ISSUED TO
ALERT THE PUBLIC THAT DANGEROUS WINTER CONDITIONS ARE LIKELY TO
OCCUR IN THE WARNED AREA, GENERALLY WITHIN THE NEXT 12 TO 36 HOURS,
OR ARE OCCURRING.  AN ADVISORY IS ISSUED TO ALERT THE PUBLIC THAT
WINTER CONDITIONS ARE EXPECTED TO CAUSE A SIGNIFICANT INCONVENIENCE
AND MAY BE HAZARDOUS.  IF CAUTION IS EXERCISED THOUGH, THESE
SITUATIONS SHOULD NOT BE LIFE THREATENING.

THE FOLLOWING WINTER STORM CRITERIA WILL BE USED FOR ALL OF NEW
HAMPSHIRE AND WESTERN AND SOUTHERN MAINE:

     BLIZZARD WARNING

          SNOW AND/OR BLOWING SNOW WILL COMBINE WITH STRONG WINDS
          TO PRODUCE NEAR-ZERO VISIBILITY.  DEEP DRIFTS AND
          DANGEROUS WIND CHILL TEMPERATURES OFTEN ACCOMPANY THESE
          CONDITIONS.  THE EXACT CRITERIA USED FOR THESE WARNINGS
          INCLUDE THE FOLLOWING CONDITIONS WHICH ARE EXPECTED TO
          PERSIST FOR 3 HOURS OR MORE.

          SUSTAINED WINDS OR FREQUENT GUSTS TO 35 MPH OR MORE...AND
          FALLING AND/OR BLOWING SNOW WHICH REDUCES VISIBILITIES TO
          1/4 MILE OR LESS.


     WINTER STORM WARNING

          AN AVERAGE OF 6 INCHES OR MORE OF SNOW/SLEET IS
          EXPECTED.

     WINTER WEATHER ADVISORY

          AN AVERAGE OF AT LEAST 4 (BUT LESS THAN 6) INCHES OF
          SNOW/SLEET IS EXPECTED ACROSS THE AREA.  WINTER WEATHER
          ADVISORIES CAN ALSO BE ISSUED FOR MIXED PRECIPITATION
          EVENTS OR FOR BLOWING SNOW.

     ICE STORM WARNING

          FREEZING RAIN IS EXPECTED TO CAUSE A GLAZE OF ICE
          1/2 INCH OR THICKER.

     FREEZING RAIN ADVISORY

          FREEZING RAIN IS EXPECTED TO CAUSE A GLAZE OF ICE ON
          ROADS AND SIDEWALKS, BUT LESS THAN 1/2 INCH IS EXPECTED.


WHILE THE NATIONAL WEATHER SERVICE DOES NOT ISSUE WARNINGS OR
ADVISORIES FOR STORMS THAT PRODUCE LESS THAN AN AVERAGE OF 4 INCHES
OF SNOWFALL...THESE STORMS CAN BE DECEPTIVELY DANGEROUS TO
MOTORISTS.  IN TERMS OF THE DEATHS THAT ARE LINKED TO THE SNOW
STORMS...THE MAJORITY ARE AS A RESULT OF TRAFFIC ACCIDENTS...AND
MANY OF THOSE ACCIDENTS OCCUR WITH ONLY SMALL ACCUMULATIONS OF SNOW.
SLOW DOWN AS SOON AS SNOW BEGINS TO ACCUMULATE.  IN ICE OR SNOW -
TAKE IT SLOW!


PREPAREDNESS TIP FOR THE DAY:

AS WAS SEEN THIS PAST WEEKEND ACROSS MID-COAST AND EASTERN MAINE,
HEAVY WET SNOW OR A SIGNIFICANT ICE ACCUMULATION...ESPECIALLY WHEN
COMBINED WITH WIND...CAN CAUSE TREES OR TREE LIMBS TO FALL ONTO POWER
LINES.  IF YOU SEE THESE CONDITIONS BEGINNING TO DEVELOP IN YOUR
AREA...PREPARE IMMEDIATELY FOR THE POSSIBILITY OF A POWER OUTAGE.
PARTICULARLY IF YOU DEPEND ON A WELL FOR WATER, STORE AN AMPLE SUPPLY
OF WATER FOR BOTH DRINKING AND SANITARY NEEDS TO LAST FOR SEVERAL
DAYS.


QUESTION OF THE DAY:

DOES A BLIZZARD WARNING MEAN THAT THERE WILL BE MORE SNOW THAN A
WINTER STORM WARNING?

  ANSWER: NOT NECESSARILY.  BLIZZARD WARNINGS ARE ISSUED FOR
  SITUATIONS WHERE THE COMBINATION OF SNOW AND/OR BLOWING
  SNOW...AND WIND WILL CAUSED REDUCED VISIBILITIES (1/4
  MILE OR LESS) FOR 3 HOURS OR LONGER.  THIS COMBINATION
  CREATES EXTREMELY HAZARDOUS CONDITIONS.  WHILE NO
  MINIMUM AMOUNT OF SNOWFALL IS REQUIRED FOR BLIZZARD
  CONDITIONS, HEAVY SNOW, NEAR ZERO VISIBILITY, DEEP
  DRIFTS, AND DANGEROUS WIND CHILLS ARE OFTEN A PART OF THESE
  HAZARDOUS WEATHER EVENTS.
