WINTER/SPRING FLOOD POTENTIAL OUTLOOK
NATIONAL WEATHER SERVICE BURLINGTON VT
1204 PM EDT THU APR 30 2015

...SPRING FLOOD POTENTIAL OUTLOOK /10/...

THIS IS THE FINAL FLOOD OUTLOOK FOR THE 2015 WINTER/SPRING
SEASON. FLOOD OUTLOOKS ARE ISSUED BI-WEEKLY THROUGH THE WINTER AND
SPRING BY THE NATIONAL WEATHER SERVICE IN BURLINGTON VERMONT TO
SUMMARIZE THE FLOOD POTENTIAL DUE TO SNOWMELT AND BREAK UP OF
RIVER ICE ACROSS CENTRAL AND NORTHERN VERMONT...AND NORTHERN NEW
YORK.

...OVERVIEW...

THE FLOOD OUTLOOK FOR CENTRAL AND NORTHERN VERMONT AND NORTHERN
NEW YORK IS NORMAL. THE POTENTIAL FOR FLOODING DUE TO ICE JAMS HAS
PASSED. SOME SNOWPACK REMAINS AT ONLY THE HIGHEST ELEVATIONS...AND
SNOWMELT CONTRIBUTIONS TO RUNOFF IS NEGLIGIBLE.

...SNOW DEPTHS AND WATER EQUIVALENT...

THE ONLY REMAINING SNOW IS AT THE HIGHEST ELEVATION MOUNTAIN
TOPS. ALTHOUGH A FOOT OR MORE OF SNOW EXISTS AT THE SUMMITS...THE
AREAL COVERAGE IS SMALL AND WOULD PROVIDE AN INSIGNIFICANT
ADDITION TO RAINFALL RUNOFF.

...RIVER AND SOIL CONDITIONS...

FROST HAS LEFT THE GROUND ACROSS THE REGION. SOILS ARE WET...WITH
RESIDUAL MOISTURE FROM SNOWMELT STILL IN THE GROUND...AND UPTAKE
FROM VEGETATION HAS NOT YET STARTED. RIVER FLOWS WERE BELOW NORMAL
ACROSS THE NORTH COUNTRY.

...WEATHER OUTLOOK...

THE NORTHEAST WILL TREND TOWARDS A MORE UNSETTLED BUT WARMER
PATTERN. THE BELOW NORMAL PRECIPITATION SEEN IN MARCH AND EARLY
APRIL WILL GIVE WAY TO MORE NORMAL PRECIPITATION AMOUNTS.
TEMPERATURES WILL TREND TOWARDS ABOVE NORMAL, AND CONTINUE TO
ALLOW SNOW MELT IN THE HIGHEST ELEVATIONS.

...SUMMARY...

THE SPRING FLOOD SNOWMELT AND ICE JAM FLOOD SEASON HAS COME TO AN
END. ANY REMAINING HIGH ELEVATION SNOW DOES NOT ADD TO ANY
SIGNIFICANT FLOOD RISK. ALL ICE IS OUT OF AREA RIVERS.

THE PROBABILITY FOR LAKE CHAMPLAIN FLOODING IS LOW BASED ON MELT
OF THE EXISTING SNOW COMBINED WITH NORMAL PRECIPITATION. THE LAKE
LEVEL REMAINS BELOW NORMAL AND HAS THE CAPACITY TO ABSORB THE
COMING SNOWMELT.

THIS IS THE FINAL WINTER/SPRING FLOOD OUTLOOK FOR THE 2015
SEASON. OUTLOOKS WILL RESUME IN JANUARY 2016.
