The causes of this situation are to be traced in the presence of semi-tropical cyclone Hans. It is an area of low pressure Coming from the Atlantic Ocean and arrived on the central Mediterranean with a South-West North-East direction, as clearly visible from the image above. Within this area the air tends to rise towards tall quotasgiving life to abundant clouds and rains – and, consequently, to the bad weather to which we are witnessing. It is a static front, to which is also added another factor given by Hans’s “impact” against the alpine chain.
