These graphs provide guidance to how a accumulation season might progress by displaying current conditions with projections into the future given the historical record at several exceedance probabilities.
Current water year is represented by the heavy red line terminating on the last day the graphic was updated.
Historical percentile range is shown as a gray background area on the graph. Shades of gray indicate different percentile bins for the period of record.
Projection exceedances are graphed as different colored lines originating at the end of the current line.
