It’s a “weather bomb.” Storm Éowyn, which is heading straight for the United Kingdom, will not spare France in the coming days. Even if the country “will not be affected by violent winds” (gusts approaching 150 km/h are expected across the Channel), according to Météo France, a lot of rain can be expected from this Thursday.
“On Friday, the cold front linked to Éowyn will water the regions of north-west France, predicted Météo France, in a bulletin published this Wednesday. In terms of wind, gusts could reach 80 to 90 km/h along the coasts on Friday, a far cry from the violent gusts which risk hitting British territory. The departments of Pas-de-Calais and Manche have been placed on youth alert for the wind for the day of Thursday.
“This Thursday, a first disturbance is expected on the Channel coasts, but precipitation should remain moderate,” forecasts La Chaîne Météo. On Friday, the cold front of Storm Eowyn will cross the north-western regions, up to the North Sea, with heavy rain. » This could last up to 24 hours, which raises fears of significant accumulations. The precipitation is expected to last well into next week.
-Storm Éowyn is born in a complex climatic situation: “Arctic air present over North America (temperatures are freezing this Wednesday in the eastern, central and southern United States) will begin to spread rapidly over the western Atlantic, explains Météo France. This will have the effect of exacerbating temperature contrasts, particularly in the depression formation zone. » According to La Chaîne Météo, this storm could be more powerful across the Channel than the Ciaran storm, in November 2023.
If we can indeed speak of a “weather bomb” regarding this storm, it is because it should “deepen” very quickly over the Atlantic, from Thursday. We are talking about “explosive cyclogenesis”, explains Météo France, still on its website. “This vigorous depression will be put on the rails of a rapid jet (tube of strong wind), which will direct it towards Ireland then Scotland,” anticipates the meteorological institute.
