  • Flood Watch issued November 22 at 1:07PM EST until November 26 at 7:00AM EST by NWS
  • Effective: Saturday, November 22, 2014 at 1:07 p.m.
  • Expires: Wednesday, November 26, 2014 at 7 a.m.
  • ...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
    COMPLETED ON FRIDAY INDICATE THAT THE SNOWPACK IN THE HARDEST HIT
    AREAS CONTAINS BETWEEN 4 AND 6 INCHES OF WATER EQUIVALENT.
    A WARMING TREND WILL GET UNDERWAY TODAY WITH AIR TEMPERATURES
    REMAINING 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.
    ...FLOOD WATCH REMAINS IN EFFECT FROM SUNDAY AFTERNOON THROUGH
    WEDNESDAY MORNING...
    THE FLOOD WATCH CONTINUES FOR
    * A PORTION OF WESTERN NEW YORK...INCLUDING THE FOLLOWING
    COUNTIES...CATTARAUGUS AND CHAUTAUQUA.
    * FROM SUNDAY AFTERNOON THROUGH WEDNESDAY MORNING.
    * SNOW MELT FROM THE RECENT SIGNIFICANT LAKE EFFECT SNOW EVENTS
    COMBINED WITH RAINFALL WILL BRING THE POTENTIAL FOR FLOODING.
    * SMALLER STREAMS AND CREEKS WILL BE PRONE TO FLOODING FROM SNOW
    MELT. THIS INCLUDES SOME OF THE CREEKS THAT FLOW THROUGH
    DUNKIRK AND SILVER CREEK. SIGNIFICANT RISES ARE ALSO POSSIBLE
    ON CATTARAUGUS CREEK. TOWNS THAT RECEIVED SIGNIFICANT AMOUNTS
    OF SNOW WILL ALSO HAVE POTENTIAL FOR URBAN FLOODING FROM THE
    SNOW MELT.
