This Monday, December 22, the weather remains particularly turbulent in the south of the country. Aveyron and Tarn are still affected by an orange alert for snow, ice and floods, while Hérault and Lozère remain on flood alert. The Var, for its part, combines the risks of rain-flooding and river overflows.
Météo France on orange alert this Monday and Tuesday
If orange vigilance has been lifted in certain departments such as Gard or Ardèche, Météo-France calls for caution, particularly in the Cévennes areas and in Provence-Alpes-Côte d’Azur, where new rainy episodes could occur.
In this unstable context, the authorities point out that the danger does not only come from the intensity of the phenomena, but also from their sudden nature. Violent storms, rapid rise in water levels or invisible patches of ice can surprise you, sometimes in just a few minutes.
Storm: seeking the right shelter can save your life
Caught in a storm, the first instinct should be to take shelter, but not just anywhere. According to Dr Gérald Kierzek, an enclosed building remains the best protection, provided you move away from windows. Failing that, a car can provide an effective refuge, provided that it is not parked under a tree and that its roof is metal. In this case, the vehicle acts like a Faraday cage, deflecting lightning toward the ground.
Conversely, some places are particularly dangerous. Flat terrain, fields, bodies of water, isolated trees or even rock walls greatly increase the risk in the event of a lightning strike.
In the great outdoors, without shelter or a car (even if this remains less common in winter!), the doctor recommends a simple but essential posture: squat, feet together, head resting on the knees, ideally sitting on a backpack to limit contact with the ground. In groups, it is crucial to move away from each other to prevent a lightning strike from passing through several people in a row.
Floods: anticipate rather than suffer
When faced with floods and floods, anticipation is essential. Even before the water rises, it is important to check that your insurance covers this type of risk and to organize your accommodation accordingly. Cellars must not be used as storage places for valuable objects, and dangerous or polluting products must be placed high up to avoid any contamination.
When the water levels begin to rise, Dr. Gérald Kierzek insists on simple but crucial actions. Important papers and valuable objects should be kept safe, ground floor openings sealed, and the gas and electricity turned off carefully, only if the installations are completely dry. Then, you must reach a refuge area in the home, if possible high up and close to a window, while remaining informed of developments in the situation.
If the authorities request an evacuation, do not hesitate. These instructions aim to protect residents and allow rapid treatment in reception centers. It’s best to pack the essentials, including warm, waterproof clothing, and leave the rest behind.
Black ice: a discreet but formidable danger
Black ice is undoubtedly one of winter’s most insidious traps. Almost invisible, it causes numerous falls each year. Dr Gérald Kierzek reminds us that we must first look carefully at where we put our feet, being particularly wary of shaded areas, which remain frozen for longer.
Caution must be applied from the threshold of the house, because the first patches of ice often form just in front of the front door. Salting your driveway and moving slowly can prevent many accidents. Leaving early also allows you to walk without rushing and choose safer routes. Finally, concentration is essential. Cell phones and distractions must be put aside to stay attentive to the ground.
And when possible, the best way to avoid a fall is still not to go out.
Staying informed, the best protection
Intense rain, floods, storms or ice: these phenomena remind us of the importance of following weather reports and safety instructions.
Adapting your travel, postponing certain activities and remaining attentive to the authorities are simple reflexes that can make a difference. As Dr Gérald Kierzek summarizes, when faced with weather hazards, vigilance and anticipation remain the best allies for our security.
