Abstract
Advances in probabilistic forecasting, notably based on ensemble prediction systems, are transforming flood risk management. Four trends shaping the assimilation of probabilistic flood forecasting into flood risk management are longer forecasting lead times, advances in decision-making aids, inclusion of probabilistic forecasting in hazard mitigation and collaboration between researchers and managers. Confronting how to use probabilistic flood forecasts to make binary management decisions for reducing flood losses requires developing institutional capacity while acknowledging flood risk estimation is one component of decision making under uncertainty in an evolving policy landscape.
