Rave-goers at Teknival in France’s Creuse region experienced plunging temperatures and unexpected snowfall on Saturday night. The weather, typically 12°C or 53.6°F this time of year, dropped to -3°C or 26.6°F (below freezing).
Approximately 10,000 were in attendance and about 30 people were treated by medics on site. Some were treated for hypothermia, after several inches of frigid snow plagued the night. It’s not atypical for the region to experience such shifts in temperature.
Festival organizers did everything they could do to help keep attendees warm. Small fires were started across the grounds and the Red Cross aided in handing out survival blankets. 
Still, two people were rushed to the hospital.
According to local media reports, the 26th installment of Teknival was unauthorized. Every year, the location changes and is revealed last-minute, as part of the underground techno movement.
The French military branch that owns the remote site reportedly submitted a formal complaint following the event.
