Instead of absolute values, the maps of 1-6 months forecasts thus show probabilities for river flow in three categories: above normal, near normal and below normal.
(ABOVE 33TH PROBABILITIES)
(BELOW 66TH PROBABILITIES)
(BETWEEN 33TH AND 66TH PROBABILITIES)
|1: High > 75% compared to near normal (NN)||2: Medium 50-75% compared to NN||3: Low < 50% compared to NN|
|4: High <-75% compared to NN||5: Medium -75% ||6: Low >-50% compared to NN
|7: Between 33th and 46th probabilities||8: Between 46th and 56th probabilities||9: Between 56th and 66th probabilities|
