Evolution of hurricane season over Northern Atlantic will be for Europe very dramatic, mainly around 14.-15. September, when towards Ireland, Scotland and Norway will shift next big windstorm with hurricane-force winds and after 18. September, when towards coast of Europe will aim the real hurricane, probably degraded to a tropical storm.
For now, the windstorm would have to hit UK and Norway around 13.-16. September, with really storm predicted wind gusts up to 167 km/h westerly from Ireland.
Possible ex-hurricane / tropical storm /ex-tropical storm could hit France around 22. September, after long-term shifting above Atlantic.
It appears, that after windstorm and before a tropical storm, cold air will move above France and Germany, therefore, tropical storm can downgrading very quickly. However, with the next possible cooldown over parts of Europe thanks to its southern stormtrack.
