WINTER/SPRING FLOOD POTENTIAL OUTLOOK
NATIONAL WEATHER SERVICE ALBANY NY
342 PM EST THU APR 18 2013

...WINTER SPRING FLOOD POTENTIAL OUTLOOK 8 FOR EASTERN NEW YORK AND
WESTERN NEW ENGLAND...

THIS IS THE EIGHTH OF A SERIES OF HYDROLOGIC OUTLOOKS ISSUED
BY THE NATIONAL WEATHER SERVICE EVERY TWO WEEKS...WHICH REFERS TO
THE POTENTIAL FOR FLOODING ACROSS EASTERN NEW YORK STATE...SOUTHERN
VERMONT...BERKSHIRE COUNTY MASSACHUSETTS...AND LITCHFIELD COUNTY
CONNECTICUT. THE MAJOR RIVER BASINS IN THIS AREA ARE THE
HUDSON...THE MOHAWK...AND THE HOUSATONIC.

THIS OUTLOOK IS VALID FOR THE TWO-WEEK PERIOD APRIL 18TH TO MAY 2ND
2013.

FLOOD POTENTIAL...
THE POTENTIAL FOR FLOODING FOR THE SPRING OF 2013 IS SLIGHTLY ABOVE
NORMAL IN THE ADIRONDACK MOUNTAINS OF NEW YORK DUE TO LINGERING
SNOWPACK AND NEAR TO BELOW NORMAL ELSEWHERE IN THE OUTLOOK AREA. THE
FLOOD POTENTIAL FROM ICE JAMS HAS PASSED FOR THE SEASON.

SNOW PACK CONDITIONS AND POTENTIAL FOR SNOWMELT FLOODING...
SNOW TOTALS IN THE ADIRONDACK MOUNTAINS OF NEW YORK REMAIN ABOVE
NORMAL. AS A RESULT...THE POTENTIAL FOR SNOWMELT FLOODING IS ABOVE
NORMAL FOR THE OUTLOOK PERIOD FOR AREAS AFFECTED BY ADIRONDACK
SNOWMELT. LINGERING SNOW AT HIGHER ELEVATIONS OF THE SOUTHERN
GREENS AND NORTHERN BERKSHIRES KEEPS THE FLOOD POTENTIAL NEAR NORMAL
IN THOSE AREAS AS WELL. ELSEWHERE ACROSS THE OUTLOOK
AREA...ESPECIALLY SOUTH OF THE MOHAWK...SNOWMELT FLOOD POTENTIAL IS
BELOW NORMAL. ESTIMATED BASIN AVERAGE SNOW WATER EQUIVALENTS ARE
LISTED BELOW...KEEP IN MIND THAT THESE WILL BE ADJUSTED TO REFLECT
THE LATEST SNOW MEASUREMENTS. FOR THE LATEST SNOW WATER EQUIVALENTS
CHECK WWW.NOHRSC.NOAA.GOV.

SOIL MOISTURE CONDITIONS...GROUND FROST...AND RUNOFF POTENTIAL...
SOIL MOISTURE IS NEAR NORMAL ACROSS THE AREA AND THE GROUND IS NO
LONGER FROZEN. AS A RESULT...RUNOFF POTENTIAL IS NEAR NORMAL FOR
THIS TIME OF YEAR.

RIVER FLOWS AND ICE CONDITIONS...
FLOWS IN AREA RIVERS ARE NEAR TO BELOW NORMAL. RIVER ICE IS NO
LONGER AN ISSUE FOR THE SEASON.

RESERVOIR AND LAKE LEVELS...
RESERVOIRS ARE NEAR TO BELOW NORMAL FOR THIS TIME OF YEAR. NYC DEP
RESERVOIRS IN THE CATSKILLS ARE ABOUT 3 PERCENT BELOW NORMAL
CAPACITY. CURRENT CATSKILL SNOW AMOUNTS ARE UNLIKELY TO MAKE UP THIS
DEFICIT...SO THESE RESERVOIRS WILL LIKELY NEED TO RELY ON RAINFALL
TO BRING THEM TO NORMAL STORAGE LEVELS.

TEMPERATURE AND PRECIPITATION...
FOR THE MONTH OF APRIL THROUGH THE 18TH...TEMPERATURES AVERAGED NEAR
NORMAL AND PRECIPITATION AVERAGED NEAR TO BELOW NORMAL.

TEMPERATURE AND PRECIPITATION FORECAST...
THE OFFICIAL NATIONAL WEATHER SERVICE 8-14 DAY OUTLOOK FOR APRIL
26TH THROUGH MAY 2ND CALLS FOR BELOW NORMAL TEMPERATURES AND NEAR
NORMAL PRECIPITATION. THE 3 MONTH SEASONAL OUTLOOK FOR MAY...JUNE
AND JULY CALLS FOR ABOVE NORMAL TEMPERATURES AND EQUAL CHANCES OF
ABOVE NORMAL...NEAR NORMAL...AND BELOW NORMAL PRECIPITATION.

IT IS IMPORTANT TO REMEMBER THAT HEAVY RAINFALL CAN PRODUCE FLOODING
ANY TIME OF THE YEAR.

IF SLOW AND STEADY SNOWMELT FROM THE HIGHEST TERRAIN OF THE OUTLOOK
AREA CONTINUES...THIS COULD BE THE FINAL SPRING FLOOD OUTLOOK FOR
THE SEASON. OTHERWISE...THE NINTH SPRING FLOOD OUTLOOK IS SCHEDULED
FOR THURSDAY...MAY 2ND 2013. EXTENDED HYDROLOGIC INFORMATION WILL BE
INCLUDED IN THE HAZARDOUS WEATHER OUTLOOK WHEN NECESSARY.
