URGENT - IMMEDIATE BROADCAST REQUESTED
FLOOD WATCH
NATIONAL WEATHER SERVICE BUFFALO NY
1051 AM EDT TUE MAR 17 2015

...ICE JAM FLOODING POSSIBLE IN CHAUTAUQUA COUNTY...

SNOWMELT AND RUNOFF FROM THE RAIN LAST NIGHT WILL PRODUCE A SLIGHT
RISE ON AREA CREEKS AND STREAMS. THIS RISE MAY BREAK UP ICE OR
CAUSE EXISTING ICE JAMS TO REPOSITION. HIGHER FLOWS WILL ALSO
CAUSE PONDING BEHIND EXISTING ICE JAMS TO RISE. THESE FACTORS
COULD STILL RESULT IN ADDITIONAL ICE JAM FLOODING.

IT IS DIFFICULT TO DETERMINE EXACTLY WHEN AND WHERE AN ICE JAM
WILL FORM. ICE JAMS MOST COMMONLY FORM WHERE THERE ARE
CONSTRICTIONS IN THE RIVER OR CREEK CHANNEL...SUCH AS SHARP
CURVES...BRIDGES...OR OTHER OBSTRUCTIONS. ICE JAMS ALSO TEND TO
OCCUR IN THE SAME LOCATIONS YEAR AFTER YEAR. PEOPLE LIVING IN
AREAS THAT ARE PRONE TO ICE JAM FLOODING SHOULD REMAIN ALERT AND
BE PREPARED IF FLOODING DOES OCCUR.

  COUNTY...CHAUTAUQUA. 

* UNTIL 9 PM EDT THIS EVENING.

* THERE CONTINUES TO BE A RISK FOR ICE JAM FLOODING IN THE WATCH
  AREA. RUNOFF FROM THE OVERNIGHT RAIN AND ABOVE FREEZING
  TEMPERATURES WILL CAUSE CREEKS AND RIVERS TO RISE MODESTLY THIS

  RESULT IN ADDITIONAL ICE JAMS AND ICE JAM FLOODING. THOSE
  LOCATED IN AREAS TYPICALLY SUSCEPTIBLE TO ICE JAMS SHOULD BE
  PREPARED TO TAKE ACTION IF FLOODING DOES DEVELOP. FALLING
  TEMPERATURES WILL DIMINISH RUNOFF AND DIMINISH THE THREAT FOR
  ADDITIONAL FLOODING LATER THIS MORNING AND THIS AFTERNOON.

* ICE JAMS ON CATTARAUGUS CREEK ARE FORMING NEAR SUNSET BAY WHICH
  PRODUCE FLOODING IN AND NEAR SUNSET BAY. 

PRECAUTIONARY/PREPAREDNESS ACTIONS...
