CONT

Probabilities or probabilistic forecasts [are] an attempt to convey the uncertainty in a forecast by expressing its likelihood of occurrence as a probability, or percentage. High probabilities do not guarantee an outcome - they merely indicate that that outcome is highly likely. Probabilities are usually based on the frequency of occurrence in the historical record. For instance, if the chance of receiving above-median rainfall in a particular climate scenario is 60%, then 60% of past years when that scenario occurred had above median rainfall, and 40% had below-median rainfall.
