During the month of February, the number of stations with exceedance has been reduced compared to the previous month. The main groups of stations are in Poland and Germany (20 stations each), in the basins of the rivers Oder, Vistula, and Rhine. These are followed by Ireland with fourteen stations in various river basins.

Additionally, there is a high concentration of stations in the Danube river basin, in Bosnia and Herzegovina, Germany, Serbia, Slovakia, and Ukraine. The Dnieper river basin also has nineteen stations showing exceedances. Some stations can also be found in southern Sweden and Croatia.

Regarding the stations that registered values above the 90% quantile, 61 exceeded this threshold in February. Of these stations, 64% were in Norway, Sweden, and Finland, as the former month.

In terms of basins, the Dnieper River in northern Ukraine is remarkable with six stations. We found a similar situation for the Glomma river (Norway) with five stations, and the Tana (Norway) and Torne (northern Sweden and Finland) rivers with four stations in the Scandinavian peninsula.

Moreover, other stations exceeded the 90% quantile value in Spain (Guadalquivir basin and eastern area), Italy (Marta river basin) and Poland (Vistula river). As for England, two stations exceeded this threshold in February and the same number in Germany (Danube and Oder rivers).

Finally, and according to the number of stations registering average values below the 10% quantile, there is a large increase in the number of stations that meet this criterion, amounting to 103 (more than 5 times the former month).

Spain stands out with 64 of these stations, with 25 stations in the Minho basin and 15 in the Douro, as well as several stations in the south of Spain. The Ebro and Llobregat basins also have five stations each with values below 10%. Spain is followed by Austria, Croatia and Hungary with six stations and Italy with five stations.

Finally, more isolated stations have values below 10% quantile, such as different basins in France, Ukraine, the Thames River (England), the Rhine in Germany or the Danube with stations in Switzerland and Romania.
