FLOOD POTENTIAL OUTLOOK FOR UTAH

THE 2014 SPRING RUNOFF FLOOD POTENTIAL DUE TO SNOWMELT IS NOT HIGH
AT THIS TIME FOR THE GREAT BASIN, AS WELL AS THE SEVIER, VIRGIN,
PRICE/SAN RAFAEL, AND THE DUCHESNE RIVER BASINS.

NO SITES ARE CURRENTLY FORECASTED TO REACH FLOOD STAGE AT THIS TIME.

SLIGHTLY ABOVE AVERAGE PEAKS MAY BE ANTICIPATED IN THE BEAR AND
WEBER RIVER BASIN AREAS, WHILE BELOW AVERAGE TO NEAR AVERAGE PEAKS
MAY BE ANTICIPATED THROUGHOUT THE REST OF THE STATE.

CURRENT VOLUME FORECASTS FOR THE APRIL THROUGH JULY RUNOFF PERIOD
ARE BELOW AVERAGE TO NEAR AVERAGE FOR MUCH OF THE STATE.  IN
PARTICULAR, VOLUME FORECASTS IN THE SOUTHERN PORTION OF THE STATE
ARE WELL BELOW AVERAGE.

IT SHOULD BE EMPHASIZED THAT SNOW ACCUMULATION CONDITIONS COULD
CHANGE SIGNIFICANTLY BEFORE RUNOFF BEGINS. ALTHOUGH SPRING
TEMPERATURES AFFECT THE PATTERN OF SNOWMELT RUNOFF AND CONSEQUENTLY
THE MAGNITUDE OF PEAK FLOWS, PEAK FLOWS ALSO ROUGHLY CORRESPOND TO
VOLUMETRIC FLOWS. IT IS ALSO IMPORTANT TO KEEP IN MIND THAT AN
EXTENDED PERIOD OF MUCH ABOVE NORMAL TEMPERATURES OR HEAVY RAINFALL
DURING THE MELT PERIOD CAN CAUSE OR EXACERBATE FLOODING PROBLEMS IN
ANY YEAR.

ADDITIONAL INFORMATION WILL BE DISSEMINATED AS CONDITIONS EVOLVE.
