In October, the highest concentration of stations (nearly 50%) that exceeded their lowest threshold level is again located in Italy, in the Po river basin, as it happened in the previous month. In central Europe the stations with their threshold level exceeded are located mainly in the east side of the Oder river basin, all stations in Poland, and in the Danube basin (Austria, Slovenia, and Hungary). Other concentrations of stations can be seen across Norway in the north and central regions, and three stations in Iceland.
According to stations registering values above the 90% quantile, these are mostly located in central Europe, mainly in the Danube basin through Austria, Czechia, Bosnia and Herzegovina, and Hungary. Other stations can be seen to a lesser degree in the Rhine basin (on the Main river in Germany) and on the Oder river through Czechia and Poland. To a minor extent, values exceeding the 90% quantile can be found in stations in the French Bourgogne region (Loire and Seine basins) and in the Rhône valley. Other stations also exceeding the 90% quantile occurred in the south of France (Adour, Garone, and Hérault basins) and in the north-east of Spain, in the Ebro basin. These values were also registered in isolated stations in the Iberian Peninsula (Doure, Minho and Velez basins), in Ireland (Shannon basin), England (Thames and Yare basins), northern Norway (Haselva and Malselv basins), one station in Sweden (Naatamo basin), and Ukraine (Dnieper basin).
Lastly, regarding values under quantile 10%, the majority of stations that meet this condition are located in Germany (Rhine, Danube, and Elbe basins), the eastern Danube basin (Romania, Hungary, Serbia, and Ukraine), the south of Sweden, and the Oder basin in Poland. We can also find stations showing values below 10% on the Thames river basin (south of England), the south of Spain, and the Dnieper basin in Ukraine. Other isolated stations also showing values below the 10% quantile are in the Lagen river (Norway), the Maritsa river (Bulgaria), and the Minho river (Spain).
