A freezing drizzle advisory is in effect for Bracebridge, Gravenhurst, Huntsville, Baysville, Port Carling, Port Severn, The Town of Parry Sound, Rosseau, and Killbear Park.
Environment Canada says the freezing drizzle should last into the morning.
Surfaces such as highways, roads, walkways and parking lots may become icy and slippery. Freezing drizzle can produce thin, hard-to-detect layers of ice. Take extra care when walking or driving in affected areas.
