Storm Alex was a powerful early-season extratropical cyclone that was particularly notable for its extreme flooding around the Mediterranean. Alex caused widespread wind and flooding damage across Europe, and at least 16 fatalities, with one more person missing. Alex was the first named storm in the 2020–21 European windstorm season. Originally, a minor low-pressure system to the south west of Greenland late on 27 September. This pressure system tracked south eastwards, experiencing the Fujiwhara effect and then undergoing explosive cyclogenesis before making landfall in Brittany on 1 October. It was named by AEMET and Météo-France on 30 September, with Red warnings being issued for wind for parts of Northern France from 16:00 CET on 1 October. The storm led to advection of Mediterranean air northwards where it interacted with the coastal topography producing an extremely heavy rainfall in southeast France, known as a "Mediterranean Episode". This brought record breaking flooding and devastation to many areas in the region. The flooding in the south of France was purportedly the worst for at least 120 years, when records began.
