The heavy rainfall storm that affected Catalonia on October 3rd and 4th could have been much more than an episode of strong storms. An analysis published on the official blog of the State Meteorological Agency (Aemet) points out that the powerful mesoscale convective system that developed off the Catalan coast showed signs compatible with an attempted formation of a tropical cyclone, a process that "had not been documented until now in the Mediterranean," as highlighted in the same work. In fact, the storm forecasts already indicated the possibility of the formation of a medicane —a Mediterranean mini-hurricane—, although it ultimately did not happen.
