The assessment of storm hazard arises in at least three guises. Firstly, the planning engineer, journalist or layperson may want to know the rarity of a given storm event. Secondly, there is the classical requirement of the hydrologist for a design rainfall estimate to input to a rainfall-runoff flood estimation method such as the Flood Studies Report (FSR) unit hydrograph/losses model. Thirdly, and slightly differently, the requirement may be to compile a dossier of a storm's role in an atmospheric pollution episode. In this case, the storm is an agent of the hazard rather than the hazard itself.
