WILL LIKELY BE AFFECTED BY UPSTREAM WATER MANAGEMENT.
THIS OUTLOOK IS BASED ON RECENT OBSERVATIONS OF SNOWPACK AND ASSUMES
NORMAL PRECIPITATION FOR THE REMAINDER OF THE SNOW SEASON. IF THE
ACTUAL OBSERVED PRECIPITATION DEVIATES FROM NORMAL...THEN THE ACTUAL
OBSERVED RUNOFF WILL LIKELY BE DIFFERENT THAN THE FORECASTS IN THIS
OUTLOOK. A FINAL OUTLOOK FOR THE 2008 WATER SUPPLY SEASON WILL BE
ISSUED IN EARLY JUNE.
USERS OF THIS PRODUCT ARE ENCOURAGED TO CONTACT THE NATIONAL WEATHER
SERVICE IN PUEBLO FOR CONTINUED UPDATES ON THE WATER SUPPLY
SITUATION. METEOROLOGICAL CONDITIONS COULD DEVELOP THAT WOULD HAVE
A SIGNIFICANT IMPACT ON WATER SUPPLY FORECASTS.
