WINTER/SPRING FLOOD POTENTIAL OUTLOOK
NATIONAL WEATHER SERVICE WILMINGTON OH
409 PM EDT FRI MAR 20 2015

...WINTER/SPRING FLOOD POTENTIAL OUTLOOK...

...FLOOD POTENTIAL THROUGH APRIL 2 IS ABOVE NORMAL ACROSS THE
REGION.

THIS OUTLOOK IS THE FOURTH IN A BIWEEKLY SERIES OF OUTLOOKS FOR THE
WINTER AND EARLY SPRING.

ABOVE NORMAL FLOOD POTENTIAL MEANS AT LEAST A CHANCE OF MORE
WIDESPREAD FLOODING WITH SOME POINTS POSSIBLY REACHING MODERATE OR
MAJOR FLOOD LEVELS.

THE FLOOD OUTLOOK IS ISSUED BY LOCAL NWS OFFICES IN WINTER AND
EARLY SPRING TO SUMMARIZE BASIN CONDITIONS AND TO ASSESS THE
POTENTIAL FOR FLOODING. THE OUTLOOKS ARE BASED ON CURRENT AND
FORECAST HYDROMETEOROLOGICAL CONDITIONS.

THE FACTORS CONSIDERED WHEN DETERMINING FLOOD POTENTIAL INCLUDE
CURRENT STREAMFLOW AND RESERVOIR LEVELS COMPARED TO NORMAL FOR
THE PERIOD...WATER EQUIVALENT IN ANY SNOW PACK...SOIL MOISTURE
AND EXPECTED PRECIPITATION.

...SNOW COVER AND SNOW WATER EQUIVALENT...
THERE IS NO LONGER A SNOWPACK OVER THE AREA.

...STREAMFLOW...
STREAMFLOW VALUES WERE ABOVE TO MUCH ABOVE NORMAL FOR MID TO LATE
MARCH ACROSS THE REGION.

...ICE...
RIVER ICE IS NO LONGER A PROBLEM.

...SOIL MOISTURE...
SOILS WERE NEARLY SATURATED ACROSS THE AREA...OPTIMIZING ANY FUTURE
RUNOFF.

...RESERVOIR CAPACITY...
AREA RESERVOIRS ARE EITHER AT OR SLIGHTLY ABOVE WINTER POOL. HOWEVER
MOST LAKES ARE STILL ONLY UTILIZING LESS THAN 20 PERCENT OF THEIR
STORAGE CAPACITY. THE HIGHEST LAKES ARE RELEASING WATER IN ORDER
TO BRING LAKE LEVELS CLOSER TO OPTIMUM FLOOD CONTROL.

...WEATHER TRENDS AND PRECIPITATION...
FOR THE FIRST WEEK OF THE OUTLOOK PERIOD...THE FIRST HALF WILL BE
DRY...WITH LIGHT RAIN SYSTEMS POSSIBLE BY MID WEEK. FOR THE 8 TO
14 DAY OUTLOOK PERIOD...BELOW NORMAL TEMPERATURES ARE FORECAST
WITH NEAR NORMAL PRECIPITATION.
