WINTER/SPRING FLOOD POTENTIAL OUTLOOK  
NATIONAL WEATHER SERVICE NEW YORK NY  
925 AM EDT THU APR 27 2017  
   
..SPRING FLOOD POTENTIAL OUTLOOK
 
 
THIS IS THE LAST SPRING FLOOD POTENTIAL OUTLOOK IN A SERIES OF  
ROUTINE SPRING FLOOD POTENTIAL STATEMENTS INTENDED TO PROVIDE  
INSIGHT INTO THE LIKELIHOOD OF RIVER FLOODING (NOT FLASH  
FLOODING)OVER THE LOWER HUDSON RIVER VALLEY...NORTHEASTERN NEW  
JERSEY...SOUTHERN CONNECTICUT...NEW YORK CITY AND LONG ISLAND.  
 
THIS OUTLOOK IS BASED ON A CURRENT ASSESSMENT OF HYDRO-  
METEOROLOGICAL FACTORS WHICH CONTRIBUTE TO RIVER FLOODING. THESE  
FACTORS INCLUDE RECENT PRECIPITATION...SOIL MOISTURE...SNOW COVER  
AND SNOW WATER EQUIVALENT...RIVER ICE...STREAM-FLOW...FUTURE WEATHER  
CONDITIONS...AND OTHERS. THIS OUTLOOK DOES NOT ADDRESS THE SEVERITY  
OF ANY FUTURE RIVER FLOODING.  
 
THE LATEST CLIMATE PREDICTION CENTER 6 TO 10 DAY OUTLOOK VALID FROM  
MAY 2ND THROUGH THE 6TH SUGGESTS NORMAL TO ABOVE NORMAL TEMPERATURES  
AND ABOVE NORMAL PRECIPITATION ACROSS THE HYDROLOGIC SERVICE AREA.  
THE 8 TO 14 DAY OUTLOOK VALID FROM MAY 4TH THROUGH THE 10TH SUGGESTS  
BELOW NORMAL TEMPERATURES AND ABOVE NORMAL PRECIPITATION ACROSS THE  
HYDROLOGIC SERVICE AREA.  
 
HEAVY RAINFALL IS THE PRIMARY FACTOR WHICH LEADS TO RIVER FLOODING.  
IT IS IMPORTANT TO NOTE THAT HEAVY RAINFALL CAN RAPIDLY CAUSE RIVER  
FLOODING ANY TIME OF THE YEAR...EVEN WHEN OVERALL RIVER FLOOD  
POTENTIAL IS CONSIDERED LOW OR BELOW NORMAL.  
 
CURRENT FLOODING - NONE.  
 
PRECIPITATION - YEAR TO DATE...PRECIPITATION DEPARTURES HAVE BEEN  
BELOW NORMAL ACROSS THE LOWER HUDSON RIVER VALLEY... NEW YORK CITY 5  
BOROUGHS...SOUTHERN CONNECTICUT AND LONG ISLAND. PRECIPITATION  
DEPARTURES ACROSS NORTHEAST NEW JERSEY HAVE BEEN NORMAL TO ABOVE  
NORMAL.  
 
SNOW DEPTH AND WATER EQUIVALENT - THERE IS CURRENTLY NO SNOW ACROSS  
THE HYDROLOGIC SERVICE AREA.  
 
RIVER FLOWS - ACROSS THE LOCAL HYDROLOGIC SERVICE AREA...FLOWS  
ACROSS AREA RIVERS AND STREAMS ARE NEAR NORMAL TO BELOW NORMAL. REAL-  
TIME WATER DATA CAN BE FOUND BY VISITING THE USGS AT  
WWW.USGS.GOV/WATER.  
 
SOIL MOISTURE - BELOW NORMAL. SOIL MOISTURE AND DROUGHT RELATED DATA  
AND CHARTS CAN BE SEEN AT: WWW.CPC.NCEP.NOAA.GOV AND WWW.DROUGHT.GOV.  
 
RESERVOIR CONDITIONS - RESERVOIR LEVELS ACROSS THE NEW YORK CITY  
WATER SUPPLY SYSTEM WAS 1 PERCENT ABOVE NORMAL. RESERVOIR LEVELS  
ACROSS THE COMBINED 13 NORTHEAST NEW JERSEY RESERVOIRS ARE 6 PERCENT  
ABOVE NORMAL.
