The Meteorological Service of Catalonia (SMC) has certified, with the data collected during this week, that the temporary ‘Gloria’, with winds of more than 100 km / h, rain of up to 500 liters per square meter and waves of 7 meters in The entire coastline is “historic” and in some places “unprecedented,” and it had not rained so much since 1932.

According to the balance that the SMC has done, the Levante storm, which has caused four deaths and one missing person in Catalonia, in addition to multimillion-dollar material damages that in some cases will take months to repair, “has been extraordinary.”

Precipitation accumulations of up to 516 liters of water per square meter in Lliurona (Girona), 1.5 meters of snow on the summits of the Girona Pyrenees, a persistent wind with gusts of more than 100 kilometers per hour – the maximum measured gust has been of 144 km / h in the Montseny-, and, above all, a maritime storm with waves of 7 meters across the coast and even up to 12 in the Ebro Delta, “unprecedented in some points”, make the ‘Gloria ‘one of the strongest storms since there are records.

The maximum rainfall collected has been at Lliurona station, in Alt Empordà, with 516 liters per square meter, followed by Puig Sesolles station, in Montseny, with 430 liters, and Viladrau (Girona) with 426, although others Many stations have collected in the four days of the storm more than 300 liters: Sant Pau de Segúries (402), Santa Pau (400), Arbúcies (356), Beget (343), Olot (339) or Tortellá (333).
