HYDROLOGIC OUTLOOK
NATIONAL WEATHER SERVICE GRAND JUNCTION CO
1133 AM MDT FRI JUN 20 2008
...SPRING FLOOD AND WATER RESOURCES OUTLOOK FOR WESTERN COLORADO AND
EASTERN UTAH...
A RIDGE OF HIGH PRESSURE WILL CONTINUE OVER THE WESTERN UNITED
STATES THIS WEEKEND AND PERSIST FOR MUCH OF NEXT WEEK. WIDE SPREAD
PRECIPITATION IS NOT EXPECTED TO HAVE A SIGNIFICANT IMPACT ON STREAM
AND RIVER FLOWS...ALTHOUGH ISOLATED THUNDERSTORMS COULD PRODUCE
LOCALIZED FLOOD CONCERNS. HOWEVER...THE WARM TEMPERATURES
ASSOCIATED WITH THE RIDGE WILL CONTINUE MELTING OFF THE HIGH
MOUNTAIN SNOW PACK.
IN WESTERN COLORADO...
THE POTENTIAL FOR SPRING 2008 FLOODING DUE TO SNOWMELT CONTINUES TO
BE HIGH FOR PORTIONS OF THE YAMPA...WHITE...GUNNISON...AND UPPER
COLORADO RIVER MAINSTEM BASINS.
BANKFULL STAGE HAS ALREADY BEEN REACHED OR EXCEEDED AT A NUMBER OF
FORECAST POINTS. FLOWS AND STAGES FOR THE CONTINUED WARM PERIOD WILL
LIKELY REMAIN STEADY OR INCREASE SLIGHTLY DURING THE COMING WEEK.
IN EASTERN UTAH...
MOST SNOW WATER EQUIVALENTS HAVE DROPPED WELL BELOW AVERAGE IN THE
RIVER BASINS ACROSS EASTERN UTAH. THEREFORE...SPRING FLOODING DUE TO
SNOWMELT IS NOT ANTICIPATED...ALTHOUGH A FEW LOCATIONS COULD
EXPERIENCE INCREASED RIVER LEVELS WITH ADDED WATER FROM COLORADO.
