Ensemble Streamflow 90-day Hydrologic Outlook
 

These graphics represent the general probabilities of exceeding minor, moderate, and major flood levels based on ensemble streamflow prediction analysis.  The long-range probabilistic outlook contains forecast values that are calculated using multiple season scenarios from 30 or more years of climatological data including current conditions of the river, snow cover, and soil moisture.  Locations on the map symbolized by small black dots are not yet modeled in such a way to provide this information.  Go to WFO AHPS pages to view more detailed probabilistic information for each river location.
