The chart consists of three heavy-rain maps for Germany regarding the following warning levels 2 – extraordinary weather, 3 – tempest, and 4 – extremely severe weather. The total hours of precipitation are shown for the period 2001 to 2022 when warning thresholds were exceeded. For level 2 this amounts to more than 15 litres per square metre in one hour and more than 20 litres in 6 hours; for level 3 the amount is more than 25 litres per square metre in one hour and more than 35 litres in 6 hours; for level 4 the amount is more than 40 litres per square metre in one hour and more than 60 litres in 6 hours. The grid cells are each coloured in seven categories of different lengths which cover various durations according to the warning level concerned: for level 2, from 0 to more than 600 hours, for level 3 from 0 to more than 80 hours and for level 4 from 0 to more than 8 hours. Lighter shades indicate shorter durations, darker shades signify longer durations. The darker shades dominate in mountain areas and in the foothills of the Alps as well as in the south of Saxony near the Czech border.
