If the forecaster is only 75% sure it will rain (C = 0.75) and if it does, only 80% of the forecast area will see that rain (A = 0.80), then. PoP = C x A. PoP = 0.75 x 0.80. PoP = 0.60 or 60% chance of precipitation. Both of these examples give the same value for the chance of precipitation but have different meanings.

What does 60% chance of rain really mean?
