The probabilistic forecasting systems ICON-CH1-EPS and ICON-CH2-EPS allow information to be deduced regarding the predictability of the forecast. Below are three regularly updated graphics for precipitation totals and the probabilities of exceeding various threshold values.
Total precipitation in the past 24 hours, as per the time displayed in the top right of the graphic (in red).
Total precipitation in the past 48 hours, as per the time displayed in the top right of the graphic (in red).
The maps generated with ICON-CH2-EPS indicate the probability (as a percentage) that a particular precipitation level (20 mm, 40 mm, 60 mm or 80 mm) will be exceeded at a particular location within 24 hours. The relevant time period is displayed in the top right of the graphic (in red).
