The AIFS Single layer shows the highest return period exceedance within the 15-day forecast range based on the AIFS single forecast. River cells above 250km2 are shown by colouring, if they are in one of the flood levels and if the 2-year flood threshold exceeds 0.1 m3/s. Yellow pixels show maximum river discharge in the 15-day period exceeding the 2-year flood threshold (at any point in the 15-day horizon), red pixels show 5-year exceedance, while purple pixels show 20-year exceedance.
