A new storm could disrupt New Year’s festivities in France. Weather models predict strong winds, particularly in coastal areas. This low pressure system raises concerns about its impacts on the territories concerned.
The storm, which could be named Éowyn, would have its source in an intense depression located off the Atlantic. This weather system is expected to develop by December 31, before intensifying as it moves towards northern Ireland and the British Isles. France, particularly the coastal regions of the Channel, Brittany and Hauts-de-France, could feel its effects from January 1.
Depressions like this form when a cold air mass meets a warm air mass, generating atmospheric instability conducive to sustained winds and heavy precipitation. This configuration suggests violent gusts and notable accumulations of rain, particularly in the northwest of the country.
Windy weather with gusts up to 130 km/h
Weather forecasts indicate gusts reaching between 100 and 130 km/h depending on the region. Models like that of Icon, often renowned for its pessimistic scenarios, predict gusts of 130 km/h in Pas-de-Calais and up to 120 km/h in Normandy and Brittany. Other models, such as the French Arpège model, are more moderate with maximum gusts around 100 km/h on land.
These violent winds could have significant consequences on infrastructure, particularly in coastal areas where buildings and equipment are often more exposed. Transport could also be disrupted, with possible cancellations of trains and flights. In addition to the winds, this storm could be accompanied by heavy precipitation.
The northwestern regions, already weakened by episodes of intense rain in December, could receive several tens of millimeters of additional rain. These conditions increase the risk of local flooding, particularly in areas already saturated with water. Forecasts at this stage still remain subject to revision. However, local authorities and emergency services are preparing to intervene quickly if the weather situation deteriorates.
A storm soon to be named Éowyn by the weather services?
If the storm meets the criteria set by the weather service, it could be named Éowyn, in line with the list of names assigned to storms by the UK Met Office. This name, of Irish origin, underlines the importance of international coordination in the management of meteorological phenomena. France, although affected second, will have to remain vigilant in the face of the possible impacts of this event.
Residents of at-risk areas are invited to follow the recommendations of the authorities and secure their homes. As the New Year festivities approach, this potential storm is a reminder of the climatic hazards common in winter. Residents of affected regions should exercise extra caution and stay informed of weather updates. This first event of the year 2025 could be the prelude to a turbulent winter season.
