In flood risk management, it would be useful to know the upper limit for the maximum precipitation at a specific site. It may be estimated by storm models, maximisation of actual storms or generalised charts. The maximum flood and maximum storm can be derived from the maximum precipitation. Since we are not very sure about these estimates, it is important to prefix ‘probable’ to the terms to emphasise the significant uncertainties with these values.
