Short summary
The health burden of extreme heat necessitates the development of effective early warning systems. These systems depend critically on the underlying weather forecasts. We compare forecasts of temperature-related mortality based on data-driven weather forecasts with those based on physics-based weather forecasts for summer 2024 in Europe. We find that forecasts based on data-driven weather forecasts could represent a promising avenue for the development of heat-related health impact forecasts.
