On October 4, 2007, a powerful squall line hit the Balearic Islands with widespread wind gusts of 130km/h. In some observatories in the interior and east of Mallorca, gusts of 183 km/h and 195 km/h respectively were measured, making this system one of the most severe in Europe in the last decade. Several supercells embedded within the system left large hail, but one of them stood out for the number of tornadoes it produced, up to 4 along the island. The first of them was a violent wedge tornado that caused severe damage to industrial warehouses, businesses and private homes in Palma de Mallorca. It was rated EF-3 and its diameter exceeded a kilometer in width at certain times.
