Linked to a major cold snap in the United States, Storm Eowyn will hit the British Isles at the end of the week. On Friday, the French coast will be subject to strong winds.
The storm Éowyn, which owes its name to the character from The Lord of the Rings, promises to be as fiery as the slayer of Nazgûl imagined by Tolkien. This phenomenon, which arrives from the United States, will mainly affect the British Isles but will have consequences on France, including a strong gale on Friday January 24.
Gusts of more than 100 km/h are expected on the French coast, particularly on the Channel coast, and will be accompanied by significant amounts of rain across the entire north-western quarter of the country. The swell should also be significant.
Interviewed by actu.fr, meteorologist Yann Amice describes storm Éowyn as “explosive cyclogenesis”. It will, according to him, “deepen very violently” by losing “more than 33 hectopascals in 24 hours”, going from 1,000 hPa to 946 hPa between Thursday and Friday.
The French weather has for several days been marked by cold and dry weather due to a powerful anticyclone on the European continent but Éowyn, which is linked to a significant cold snap in the United States, will change that.
-This American context will in fact “revitalize the jet stream, a very powerful upper-altitude wind axis across the entire Atlantic, causing depressions to run aground over Europe,” explains Yann Amice.
This will result in a rise in temperatures but also in much more disrupted weather, with a lot of rain and wind. After Éowyn, other depressions could therefore arrive in Western Europe, carried by this westerly current.
A system near the Portuguese Azores islands has already been identified and could approach the coast of Brittany, causing strong gusts until the beginning of next week.
