Seasonal rainfall totals for spring (April to June) and summer (April to October) in northern Portugal from 1980 to 2017. The shaded areas represent rainfall totals from the bias-corrected hindcasts. The solid black lines show observed rainfall totals from CHIRPS [15], and the dashed black lines indicate the highest observed values. Unprecedented rainfall totals are apparent when the modelled rainfall totals lie above the dashed line in each panel.
