The Ontario Federation of Snowmobile Clubs is warning sledders to keep their machines parked despite the snow in the forecast for the weekend.
The OFSC says the conditions would be very poor, as the ground, waterways, and swamps are not frozen.
They warn that there will not be enough snow base to protect the sled and operator from terrain irregularities and obstacles.
OFSC trails are not open to riders and access to private property remains closed. Snowmobilers are also being told to stay off public roads, and avoid trespassing on farmer's fields.
The OFSC promises winter and the 2016 snowmobiling season is on it's way.
The OFSC issued the same warning last year after a significant snowfall November 14.
Last year, OPP responded to 15 crashes on the roads on during the first appearance of winter in mid November.
