The decision making process begins several months ahead of the target season. Seasonal forecasts from the climate information provider are collated. These forecasts are then processed and used within the mortality model to generate excess mortality forecasts. These probabilistic mortality forecasts are then transferred to the users. Although there is a large amount of uncertainty in long-lead seasonal climate forecasts for Europe, these preliminary mortality forecasts can be used to take initial decisions. For example, allocating the necessary resources to prepare for any anticipated heat waves or cold spells while considering other contextual information. Just before the target season, additional, shorter range, sub-seasonal forecasts are used to refine the mortality forecasts and considered with updated contextual information. Finally, localised action plans are implemented ahead and during the heat wave/cold spell events, to protect vulnerable sectors of society.
