...LIVINGSTON...ONTARIO...NORTHERN CAYUGA...OSWEGO
...LEWIS...JEFFERSON...

RECORD RAINFALL OF 2.5 TO 4 INCHES SINCE LATE WEDNESDAY AFTERNOON HAS 
CAUSED EXTENSIVE URBAN AND SMALL STREAM FLOODING ACROSS WESTERN AND 
CENTRAL NEW YORK...WITH NUMEROUS ROADS UNDERWATER AND CLOSED TO
TRAFFIC. WHILE THE STEADY HEAVY RAIN ENDED DURING THE EVENING
HOURS...SHOWERS CONTAINING AN ADDITIONAL HALF INCH OF RAIN ARE 
POSSIBLE DURING THE OVERNIGHT AND EARLY MORNING HOURS. THIS WILL 
AGGREVATE AN ALREADY DANGEROUS SITUATION ALONG MANY LOCAL CREEKS AND 
STREAMS. 

MANY CREEKS AND STREAMS FROM THE GENESEE VALLEY EAST ACROSS THE 
FINGER LAKES WILL REMAIN OUT OF THEIR BANKS OVERNIGHT CAUSING 
NUMEROUS ROAD CLOSURES. SOME HOMES WILL REMAIN THREATENED WITH
BASEMENT FLOODING A PROBLEM.

THE LARGER CREEKS IN THE BUFFALO AREA REMAIN UNDER A FLOOD WARNING 
AND THESE INCLUDE THE ELLICOTT AND TONAWANDA CREEKS.

MEANWHILE...MOST SMALLER CREEKS AND STREAMS OVER THE FAR WESTERN 
COUNTIES HAVE RETURNED TO WITHIN THEIR BANKS...ALTHOUGH LOWLAND 
FLOODING COULD STILL BE A PROBLEM THROUGH DAYBREAK. ADDITIONAL 
RAINFALL BY DAYBREAK SHOULD AGGREVATE THE SMALLER STREAMS ACROSS FAR 
WESTERN NEW YORK...BUT THEY ARE NOT EXPECTED TO OVERFLOW THEIR BANKS 
A SECOND TIME.

REMEMBER A WARNING MEANS THAT FLOODING IS IMMINENT OR IS OCCURRING. 
THOSE PERSONS WITH INTERESTS NEAR SMALL STREAMS AND CREEKS OR IN LOW 
LYING AREAS SHOULD CONTINUE TO TAKE NECESSARY PRECAUTIONS IMMEDIATELY 
TO PROTECT LIFE AND PROPERTY.
 
DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE 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.

AN UPDATED STATEMENT WILL BE ISSUED BY 5AM FRIDAY MORNING.
