URGENT - IMMEDIATE BROADCAST REQUESTED
FLOOD WATCH
NATIONAL WEATHER SERVICE BUFFALO NY
338 PM EST FRI NOV 21 2014

...SIGNIFICANT FLOODING POSSIBLE EARLY NEXT WEEK...

TWO SIGNIFICANT LAKE EFFECT SNOW EVENTS THIS WEEK HAVE BROUGHT A
VERY DEEP SNOWPACK ACROSS PORTIONS OF WESTERN NEW YORK. THIS
SNOWPACK NOW STORES A LARGE QUANTITY OF WATER. SNOW SURVEYS TODAY
INDICATE THAT THE SNOWPACK IN THE HARDEST HIT AREAS CONTAINS
BETWEEN 4 AND 6 INCHES OF WATER EQUIVALENT. AFTER THE LAKE EFFECT
SNOW ENDS...A WARMING TREND WILL START EARLY THIS WEEKEND. BY
SATURDAY AFTERNOON AIR TEMPERATURES WILL RISE ABOVE FREEZING
AND THEN REMAIN ABOVE FREEZING THROUGH TUESDAY NIGHT. DAYTIME
HIGHS WILL RISE TO NEAR 50 F DEGREES ON SUNDAY...AND NEAR 60 F
DEGREES ON MONDAY. IN ADDITION TO THE WARMING AIR TEMPERATURES...A
SOUTHERLY BREEZE AND RISING DEW POINTS WILL MAKE FOR A MORE
EFFICIENT MELTING OF THE SNOWPACK.

AT FIRST THE SNOWPACK WILL ABSORB MUCH OF THE WATER FROM THE SNOW
MELT. HOWEVER AS THE SNOWPACK RIPENS...AND WITH THE ADDITION OF A
HALF INCH OR SO OF RAINFALL SUNDAY NIGHT AND MONDAY...THE
POTENTIAL FOR FLOODING WILL RAPIDLY INCREASE.

PEOPLE LIVING IN AREAS PRONE TO FLOODING...AND WHERE SIGNIFICANT
AMOUNTS OF SNOW FELL SHOULD TAKE TIME IN ADVANCE OF THE WARMING
TO PREPARE FOR THE POTENTIAL FOR SIGNIFICANT FLOODING EARLY NEXT
WEEK. IN ADDITION TO CREEKS AND SMALL STREAMS FLOODING THEIR
BANKS...GENERAL FLOODING IS POSSIBLE ACROSS TOWNS WHERE SEVERAL
FEET OF SNOW FELL. DRAINS MAY BE CLOGGED WITH SNOW AND LEAVES...
AND THE MASSIVE AMOUNTS OF SNOW MAY PREVENT WATER FROM DRAINING
EFFICIENTLY.

  MELT. THIS INCLUDES SOME OF THE CREEKS THAT FLOW THROUGH DUNKIRK
  AND SILVER CREEK. TOWNS THAT RECEIVED SIGNIFICANT AMOUNTS OF
