The small slide happened near Moat and Circlet Lakes in Strathcona Provincial Park, according to a statement issued by Cpl. Darren Lagen.
"The group used a cellphone to call for help, leading to the activation of the Comox Valley Search and Rescue Team and the Comox Valley RCMP," said Lagen.
A spokesman for Comox Search and Rescue said it appears nobody was buried or trapped in the slide.
The group was about two kilometres away from the Mount Washington Alpine Resort when the slide occurred, an official at the resort said.
RCMP said a command centre had been set up at the Raven Lodge at the resort and rescue technicians were using snow machines to reach the group.
The Vancouver Island Avalanche Centre rated the avalanche danger for areas at the treeline or higher as considerable on Tuesday.
Heavy snow is expected in the area overnight as part of a major storm passing over southern B.C.
