WINTER/SPRING FLOOD POTENTIAL OUTLOOK
NATIONAL WEATHER SERVICE ALBANY NY
445 PM EST THU APR 4 2013

...WINTER SPRING FLOOD POTENTIAL OUTLOOK 7 FOR EASTERN NEW YORK AND
WESTERN NEW ENGLAND...

THIS IS THE SEVENTH 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 4TH TO APRIL
18TH 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 A LINGERING
DEEP SNOWPACK AND NEAR TO BELOW NORMAL ELSEWHERE IN THE OUTLOOK
AREA. THE FLOOD POTENTIAL FROM ICE JAMS IS BELOW NORMAL IN THE UPPER
HUDSON WHERE ICE REMAINS AND OVER FOR THE SEASON ELSEWHERE.

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. ELSEWHERE ACROSS THE OUTLOOK AREA...LINGERING SNOW AT
HIGHER ELEVATIONS KEEPS THE FLOOD POTENTIAL NEAR NORMAL. ESTIMATED
BASIN AVERAGE SNOW WATER EQUIVALENTS ARE LISTED BELOW...KEEP IN MIND
THAT THESE WILL BE ADJUSTED TO REFLECT THE LATEST SNOW MEASUREMENTS
WITH SIGNIFICANT ADJUSTMENTS POSSIBLE BY THE END OF THE WEEK. 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...WITH THE
EXCEPTION OF ICE ON THE HUDSON AND SCHROON RIVERS ABOVE THEIR
CONFLUENCE...IS NO LONGER AN ISSUE FOR THE SEASON.

RESERVOIR AND LAKE LEVELS...
RESERVOIRS ARE NEAR TO BELOW NORMAL FOR THIS TIME OF YEAR.
RESERVOIRS IN THE ADIRONDACKS ARE BELOW NORMAL BUT HAVE PLENTY OF
SNOWPACK TO MAKE UP THE DEFICIT...WHILE NYC DEP RESERVOIRS IN THE
CATSKILLS ARE ABOUT 4 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 MARCH...TEMPERATURES AND PRECIPITATION AVERAGED
BELOW NORMAL.

TEMPERATURE AND PRECIPITATION FORECAST...
THE OFFICIAL NATIONAL WEATHER SERVICE 6-10 AND 8-14 DAY OUTLOOKS FOR
APRIL 9-13 AND 11-17 RESPECTIVELY...CALL FOR ABOVE NORMAL
TEMPERATURES AND PRECIPITATION. THE 3 MONTH SEASONAL OUTLOOK FOR
APRIL...MAY AND JUNE 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.

THE EIGHTH SPRING FLOOD OUTLOOK IS SCHEDULED FOR THURSDAY...APRIL
18TH 2013. EXTENDED HYDROLOGIC INFORMATION WILL BE INCLUDED IN THE
HAZARDOUS WEATHER OUTLOOK WHEN NECESSARY.
