ORANGE HEATWAVE AND YELLOW STORM WARNING FOR HAUTE-MARNE

Updated on 28/06/2026

Since 06:00, Météo France has placed the Haute-Marne department under an orange heatwave warning and a yellow storm warning

Following several days of an exceptionally intense heatwave, temperatures will remain high and continue to affect the health of the most vulnerable individuals as well as natural environments.

The prefect of Haute-Marne urges everyone to maintain responsible behavior and not to reduce the efforts made over the past several days.

Reminder of essential precautions to continue observing:

* Drink water several times a day,

* Avoid alcohol consumption,

* Try to spend several hours each day in a cool or air-conditioned place,

* Keep your home cool: close shutters, curtains, and windows during the day, and ventilate at night,

* Avoid going out during the hottest hours (11 a.m.–9 p.m.) and prefer shorter outings that require minimal effort,

* Swim only in supervised areas,

* Take special care of the most vulnerable: elderly people, babies, and young children, making sure they stay hydrated. For elderly individuals with chronic illnesses or those isolated in your circle, check in on them and visit if possible,

* Think about animals: provide them with water and never leave them in direct sunlight or in a vehicle

Particular attention must continue to be paid to elderly, isolated, disabled individuals, or those suffering from chronic illnesses. Family members, neighbors, friends, and caregivers are encouraged to maintain regular contact with these individuals and to check on their health status.

Maximum vigilance near water sources

With the intense heat, visits to swimming pools, lakes, and rivers are increasing, in line with recommendations to cool down. Numerous deaths have been recorded nationally. Before swimming, one must gradually enter the water, especially after prolonged sun exposure or physical exertion, to reduce the risk of cold water shock.

Risk of forest fires

Vegetation remains particularly vulnerable to fire outbreaks, and any risky behavior may lead to serious consequences. 9 out of 10 forest fires are human-caused and could be prevented by adopting the right reflexes.

In case of thunderstorms

The yellow weather warning for thunderstorms also calls for caution. It is recommended to:

• monitor the evolution of the weather situation and prevention guidelines

• limit outdoor activities during thunderstorms

• stay away from trees, watercourses, and metal structures during thunderstorms

• Secure objects that could be blown away by the wind and avoid non-essential travel during the most intense events.

The prefect draws the attention of camping operators and organizers of outdoor events to ensure all necessary measures are taken to secure property and protect people.
