Woman missing after severe storm in Sixt-Fer-a-Cheval

Sixt-Fer-a-Cheval – 05.08.2026: Following the severe thunderstorms on Tuesday evening, a woman around 50 years old remains missing in Sixt-Fer-a-Cheval in the Haute-Savoie department. Franceinfo reported on Wednesday that her whereabouts were still unknown after the storm. No information about her identity, the circumstances of her disappearance or her last known location was initially released.

The thunderstorms hit the municipality on the evening of August 4. Heavy rainfall can cause streams to swell within a short time in mountainous regions, make paths impassable and destabilize slopes. However, on Wednesday there was no reliable public information as to whether the missing woman may have been caught by a watercourse, a landslide or another consequence of the storm.

Sixt-Fer-a-Cheval is located in the Giffre Valley near the Swiss border and extends across extensive mountain and natural areas. According to the Haute-Savoie prefecture, the municipality is exposed to various natural hazards. Official risk plans are in place for the area, including flooding and flash floods around the Giffre. However, these precautionary documents do not allow any conclusions to be drawn about the current disappearance.

Search operations in alpine terrain are particularly difficult when watercourses, gorges, forest paths or steep slopes are involved. In addition to the large area, possible damage to paths and the risk of further slope movements complicate the work. The incident command must also ensure the safety of search personnel. It was initially not officially confirmed whether firefighters, gendarmes, rescue dogs, drones or helicopters had been deployed. There was also no verified information about other people affected or property damage.

Haute-Savoie regularly warns of risks to road traffic, leisure activities and stays in the mountains during heavy rain and thunderstorms. In summer, the region’s valleys and hiking areas are heavily visited. The Cirque du Fer-a-Cheval is one of the best-known excursion destinations in the Giffre Valley; its information center is open daily in August. Whether the missing woman was in the area as a visitor or resident remained unclear.

The responsible authorities initially provided no further details about the progress of the search. For relatives and local residents, this means continued uncertainty. Neither a death announcement nor an all-clear had been issued by Wednesday. At that point, the only publicly confirmed information was that the woman remained missing after the August 4 thunderstorm.
