FLASH FLOOD STATEMENT
NATIONAL WEATHER SERVICE ALBANY NY
918 PM EST MON OCT 27 2003

IN EASTERN NEW YORK
     GREENE AND ULSTER

THE NATIONAL WEATHER SERVICE HAS CANCELLED THE FLASH FLOOD WARNING 
WHICH WAS IN EFFECT FOR GREENE AND ULSTER COUNTIES.  THE RAIN HAS 
MOVED EAST OF THE AREA.

DESPITE THE HEAVY RAIN WHICH FELL OVER THE WARNING AREA TODAY...NO 
SIGNIFICANT FLOODING WAS REPORTED.

RAINFALL AMOUNTS WERE GENERALLY IN EXCESS OF ONE INCH AND A NUMBER 
OF LOCATIONS REPORTED OVER TWO INCHES. HAINES FALLS IN GREENE COUNTY 
RECEIVED 3.5 INCHES OF RAIN.

MANY STREAMS ARE SWOLLEN AND SOME ARE NEAR BANKFULL.  ADDITIONAL 
RUNOFF IS LIKELY OVERNIGHT AND CAUTION IS STILL ADVISED. 

FLOODING OF POORLY DRAINED LOW LYING AREAS IS MUCH MORE LIKELY TO 
OCCUR AT THIS TIME OF YEAR AS LEAVES THAT HAVE FALLEN OFF THE TREES 
AND LOOSE DEBRIS OFTEN BLOCK STORM DRAINS...AND CAUSE PONDING OF 
WATER ON ROADWAYS.

BE ESPECIALLY CAUTIOUS AT NIGHT WHEN IT IS HARDER TO RECOGNIZE THE 
DANGERS OF FLOODING. DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE 
WATER COVERS THE ROADWAY. THE WATER DEPTH MAY BE TOO GREAT TO ALLOW 
YOUR CAR TO CROSS SAFELY. VEHICLES CAUGHT IN RISING WATER SHOULD BE 
ABANDONED QUICKLY. MOVE TO HIGHER GROUND.

TO REPORT SEVERE WEATHER HAVE THE NEAREST LAW ENFORCEMENT AGENCY 
RELAY YOUR REPORT TO THE NATIONAL WEATHER SERVICE FORECAST OFFICE.
