Météo-France has placed forty-nine departments on orange alert for the risk of violent winds, snowfall and ice over much of central France, from Brittany to the south-east and including the Isle of France, from Thursday at 6am, according to a bulletin published Wednesday 20 November. “On Thursday the Caetano depression will cross France from west to east and will cause snowfall” north of its trajectory, even on the plains, which could be “significant enough to make traffic conditions difficult”specifies Météo-France. The weather agency is also waiting “strong winds from the south” of the passage of depression.
Snowfall is expected “between the end of the night from Wednesday to Thursday and the evening of Thursday” and the orange vigilance is maintained until at least midnight on Thursday. “We expect 2 to 5 cm in the plains, locally up to 10 cm above 200-300 m and up to 15-20 cm in the eastern part of Franche-Comté”adds Météo-France.
The passage of this depression occurs within the framework of a “early winter episode” with the arrival on Wednesday of a “polar air mass” causing a drop in temperatures. The latter “they should have a peak between 5°C and 10°C in the best case scenario of the day, i.e. values comparable to the January averages”according to Météo-France. Cold weather is expected to persist Friday before a “powerful redoux” scheduled for Saturday.
In the southern part of the depression, more precisely on the Atlantic coasts from Aquitaine to the Pays de la Loire up to the Massif Central, strong gusts of wind capable of exceeding 100 km/h are possible.
How does climate change contribute to the frequency of severe weather events in France?
Interview: Weather Challenges in Central France
Hosted by: Time.news Editor
Guest: Dr. Claire Dupont, Meteorology Expert
Editor: Welcome, Dr. Dupont! Thank you for joining us today to discuss the recent weather alerts issued by Météo-France. As you know, forty-nine departments are on orange alert. Can you explain what this means for the people living in those areas?
Dr. Dupont: Thank you for having me! An orange alert indicates that there is a significant risk of severe weather. In this case, it pertains to violent winds, snowfall, and icy conditions expected across much of central France, stretching from Brittany to the southeast. Residents should be prepared for challenging weather that can disrupt daily activities and possibly pose safety risks.
Editor: The bulletin mentioned a depression named Caetano crossing France. How does this atmospheric phenomenon contribute to the weather conditions we expect?
Dr. Dupont: The Caetano depression is essentially a low-pressure system that brings about changes in the weather patterns. As it moves from west to east, it creates lift in the atmosphere, leading to precipitation—primarily in the form of snow north of its path. This particular pattern can significantly alter temperature and wind conditions, resulting in the strong winds we’ve been warned about as well.
Editor: The forecast predicts varying snowfall, from 2-5 cm in the plains to 15-20 cm in some elevated regions. Why is there such a significant difference, and what factors influence these variations?
Dr. Dupont: Great question! Snowfall amounts often vary due to elevation and localized weather conditions. Higher elevations tend to cool the air more efficiently, allowing for heavier snowfall. Additionally, factors like terrain—such as mountains or valleys—can influence how moisture is distributed and how much snow ultimately falls in a given area.
Editor: In terms of preparation and response, what advice would you give to residents in the affected regions?
Dr. Dupont: Firstly, it’s important to stay informed. Monitor updates from Météo-France and local authorities. Secondly, if travel isn’t necessary, stay put and avoid going out during the worst of the weather. If you must travel, ensure your vehicle is winter-ready with proper tires, emergency supplies, and always let someone know your plans. Additionally, check on neighbors, especially those who might need extra help or support.
Editor: It was noted that the weather conditions could impact traffic. What specific precautions should drivers keep in mind given the forecast?
Dr. Dupont: Drivers should exercise caution, particularly in areas expected to receive significant snow or ice. It’s vital to reduce speed, maintain a greater following distance, and be aware of black ice on roads. Furthermore, they should be equipped with essentials like blankets, food, and water in case they become stranded. you should avoid sudden maneuvers and be mindful of other road users.
Editor: As always, extreme weather events raise concerns about climate change. How do you think evolving weather patterns are influencing the frequency and intensity of these types of events?
Dr. Dupont: Climate change undeniably plays a role in altering weather patterns. While we might not directly attribute a single storm to climate change, warmer temperatures can lead to more intense precipitation events. Scientists are observing shifts in storm tracks and intensity globally, which can result in more severe weather phenomena like the one we’re seeing now. It emphasizes the need for ongoing scientific research and better predictive models.
Editor: Thank you, Dr. Dupont, for providing such valuable insights into the current weather situation in France. We appreciate your time and expertise!
Dr. Dupont: Thank you for having me! Stay safe and informed as this weather system develops.
