A woman in her late 30s has been airlifted to hospital in critical condition after a serious crash in Whistler, B.C.

Whistler RCMP responded to a call just before 7:30 a.m. Sunday about a two-vehicle accident on Highway 99.

Mounties say a car travelling northbound on the highway, just north of Nordic, lost control and slid into the southbound lane.

A minivan travelling southbound collided with the car on the passenger side.

Sgt. Rob Knapton says the female driver of the car was airlifted to hospital with critical injuries, while the two occupants of the minivan were shaken, but uninjured.

He says it was snowing at the time but investigators are still determining the cause of the crash.

“It snowed overnight and it’s got a couple of inches of snow on the ground and it is a little bit slippery out and we’re looking into if that was a contributing factor or not,” Knapton said.

Knapton reminded drivers to be prepared for snowy conditions and drive with caution.

“It’s important for people to remember that they need to drive according to conditions and make sure they’ve got snow tires or appropriate equipment in their vehicles so that they can handle it,” he said. “When it snows like this especially after a long period without snow, just [remember] to slow down.”

RCMP and traffic services are currently investigating.
