Atlantic hurricanes that transition into midlatitude storms at high latitudes can affect Europe, in some cases leading to high-impact windstorms. Sainsbury et al.  compared the climatology and intensity distributions of post-tropical cyclones and midlatitude storms impacting Europe (separated into northern and southern Europe) during the Atlantic hurricane seasons from 1979 to 2017 using the ERA-5 reanalysis. They found that, although post-tropical storms are a relatively small component of the total cyclones affecting Europe, they disproportionally impact Europe with high intensity. Furthermore, in a warmer climate, post-tropical cyclones are expected to increase and frequency, which could potentially increase their risk to Europe.
